You are thereby part of a story that started long ago, when the McCulloch Corporation started its manufacturing of engines during World War II. In 1949, when McCulloch introduced its first light one-man chainsaw, woodworking would never be the same again.The line of innovative chainsaws would continue over the decades, and business was expanded, first by airplane and kart engines in the 1950s, then by mini chainsaws in the 1960s. Later, in the 1970s and 80s, trimmers and blower vacs were added to the range.Today, as a part of the Husqvarna group, McCulloch continues the tradition of powerful engines, technical innovations, and strong designs that have been our hallmarks for more than half a century. Lowering fuel consumption, emissions and noise levels are of top priority to us, as is improving safety and user-friendliness.We certainly hope that you will be satisfied with your McCulloch product, as it is designed to be your companion for a long time. By following this operators manual’s advice on usage, service, and maintenance, its lifespan can be extended. If you should need professional help with repair or service, please use the Service Locator at www.mcculloch.com.McCulloch has a policy of continuous product development and therefore reserves the right to modify the design and appearance of products without prior notice.This manual can also be downloaded at www.mcculloch.com.

GENERAL SAFETY PRECAUTIONS English – 91154657-49 Rev.5 2013-12-10 ImportantAlways use common sense (2) It is not possible to cover every conceivable situation you can face when using a chain saw. Always exercise care and use your common sense. Avoid all situations which you consider to be beyond your capability. If you still feel uncertain about operating procedures after reading these instructions, you should consult an expert before continuing. Do not hesitate to contact your dealer or us if you have any questions about the use of the chain saw. We will willingly be of service and provide you with advice as well as help you to use your chain saw both efficiently and safely. Attend a training course in chain saw usage if possible. Your dealer, forestry school or your library can provide information about which training materials and courses are available. Work is constantly in progress to improve the design and technology - improvements that increase your safety and efficiency. Visit your dealer regularly to see whether you can benefit from new features that have been introduced. Personal protective equipment • Approved protective helmet• Hearing protection• Protective goggles or a visor• Gloves with saw protection• Trousers with saw protection• Boots with saw protection, steel toe-cap and non-slip sole• Always have a first aid kit nearby.• Fire Extinguisher and ShovelGenerally clothes should be close-fitting without restricting your freedom of movement. Machine '''' s safety equipment In this section the machine’s safety features and their function are explained. For inspection and maintenance see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. See instructions under the heading, What is what?, to find where these parts are located on your machine.The life span of the machine can be reduced and the risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information please contact your nearest servicing dealer.IMPORTANTThis chain saw for forest service is designed for forest work such as felling, limbing and cutting.You should only use the saw with the bar and chain combinations we recommend in the chapter Technical data.Never use the machine if you are fatigued, while under the influence of alcohol or drugs, medication or anything that could affect your vision, alertness, coordination or judgement. Wear personal protective equipment. See instructions under the heading ”Personal protective equipment”.Do not modify this product or use it if it appears to have been modified by others.Never use a machine that is faulty. Carry out the checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualified specialists. See instructions under the heading Maintenance.When not in use, always store the integrated combi-tool in the tool-holder. Do not use the tool-holder for other purposes than to hold the supplied combi-tool, since the tool-holder is exclusively designed for this purpose.Never use any accessories other than those recommended in this manual. See instructions under the headings Cutting equipment and Technical data.CAUTION Always wear protective glasses or a face visor to reduce the risk of injury from thrown objects. A chain saw is capable of throwing objects, such as wood chips, small pieces of wood, etc, at great force. This can result in serious injury, especially to the eyes. WARNING Running an engine in a confined or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning. WARNING Faulty cutting equipment or the wrong combination of bar and saw chain increases the risk of kickback Only use the bar/saw chain combinations we recommend, and follow the filing instructions. See instructions under the heading Technical data. WARNING Most chain saw accidents happen when the chain touches the operator. You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment. IMPORTANT Sparks can come from the muffler, the bar and chain or other sources. Always have fire extinguishing tools available if you should need them. Help prevent forest fires. GENERAL SAFETY PRECAUTIONS 10 – English 1154657-49 Rev.5 2013-12-10 Chain brake and front hand guard Your chain saw is equipped with a chain brake that is designed to stop the chain if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.Take care when using your saw and make sure the kickback zone of the bar never touches any object.• The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism. (3) • The brake is applied when the front hand guard (B) is pushed forwards. (3) • This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum). (4) • The front hand guard is not designed solely to activate the chain brake. Another important feature is that it reduces the risk of your left hand hitting the chain if you lose grip of the front handle.• The chain brake must be engaged when the chain saw is started to prevent the saw chain from rotating.• Use the chain brake as a ”parking brake” when starting and when moving over short distances, to reduce the risk of moving chain accidentally hitting your leg or anyone or anything close by.• To release the chain brake pull the front hand guard backwards, towards the front handle.• Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw firmly and not let go.• The way the chain brake is activated, either manually or automatically by the inertia release mechanism, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes.If you get a violent kickback while the kickback zone of the bar is farthest away from you the chain brake is designed to be activated by the inertia in the kickback direction.If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake is designed to be activated manually by the movement of your left hand.• In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action. (8) Will my hand always activate the chain brake during a kickback? No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force may not be enough to trigger the chain brake. You should also maintain a firm grip of the chain saw handles while working. If you do and experience a kickback, your hand may never leave the front handle and will not activate the chain brake, or the chain brake will only activate after the saw has swung around a considerable distance. In such instances, the chain brake might not have enough time to stop the saw chain before it touches you.There are also certain positions in which your hand cannot reach the front hand guard to activate the chain brake; for example, when the saw chain is held in felling position. Will my inertia activated chain brake always activate during kickback in the event of a kickback? No. First your brake must be in working order. Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do before you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance. Will my chain brake always protect me from injury in the event of a kickback? No. First, the chain brake must be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the saw chain. Third, the chain brake may be activated but if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you. Only you and proper working technique can eliminate kickback and its danger. Throttle lockout The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This arrangement means that the throttle control is automatically locked at the idle setting. (5) WARNING Never use a machine with defective safety components. Safety equipment must be inspected and maintained. See instructions under the heading Checking, maintaining and servicing chain saw safety equipment. If your machine does not pass all the checks, take the saw to a servicing dealer for repair. GENERAL SAFETY PRECAUTIONS English – 111154657-49 Rev.5 2013-12-10 Chain catcher The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions). Right hand guard Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle. Vibration damping system Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.The machine ' s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine ' s handle unit. The body of the chain saw, including the cutting equipment, is insulated from the handles by vibration damping units.Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level. Stop switch Use the stop switch to switch off the engine. (28) Muffler The muffler is designed to reduce noise levels and to direct exhaust fumes away from the user.In areas with a hot, dry climate there is a high risk of fires. These areas are sometimes subject to government rules requiring among other things the muffler must be equipped with an approved type of spark arrestor screen (A). (7) Cutting equipment This section describes how to choose and maintain your cutting equipment in order to:• Reduce the risk of kickback.• Reduce the risk of the saw chain breaking or jumping off the bar.• Obtain optimal cutting performance.• Extend the life of cutting equipment.• Avoid increasing vibration levels. General rules • Only use cutting equipment recommended by us See instructions under the heading Technical data.• Keep the chain’s cutting teeth properly sharpened Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.• Maintain the correct depth gauge setting Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback.• Keep the chain properly tensioned If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.• Keep cutting equipment well lubricated and properly maintained A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket. WARNING Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the fingers, hands or wrists. These symptoms may be increased in cold temperatures. WARNING The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material CAUTION The muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours. WARNING Never use a saw without a muffler, or with a damaged muffler. A damaged muffler may substantially increase the noise level and the fire hazard. Keep fire fighting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen. GENERAL SAFETY PRECAUTIONS 12 – English 1154657-49 Rev.5 2013-12-10 Cutting equipment designed to reduce kickback The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything.By using cutting equipment with ”built-in” kickback reduction and keeping the chain sharp and well-maintained you can reduce the effects of kickback. Guide barThe smaller the tip radius the lower the chance of kickback.Saw chainA chain is made up of a number of links, which are available in standard and low-kickback versions.Some terms that describe the bar and chainTo maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend.Guide bar• Length (inches/cm)• Number of teeth on bar tip sprocket (T). • Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.• Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket.• Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links.• Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design.Saw chain• Chain pitch (inches)• Drive link width (mm/inches)• Number of drive links.Sharpening your chain and adjusting depth gauge settingGeneral information on sharpening cutting teeth• Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings.• A sharp chain eats its way through the wood and produces long, thick chips or shavings.• The cutting part of the chain is called the cutter and consists of a cutting tooth (A) and the depth gauge (B). The cutters cutting depth is determined by the difference in height between the two (depth gauge setting (C)). (9)When you sharpen a cutting tooth there are four important factors to remember.1 Filing angle2 Cutting angle3 File position4 Round file diameterIt is very difficult to sharpen a chain correctly without the right equipment. We recommend that you use our file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.See instructions under the heading Technical data for information about sharpening your chain.Sharpening cutting teethTo sharpen cutting teeth you will need a round file and a file gauge. See instructions under the heading Technical data for information on the size of file and gauge that are recommended for the chain fitted to your chain saw.• Switch the engine off. (28)• Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difficult to sharpen correctly.• Always file cutting teeth from the inside face. Reduce the pressure on the return stroke. File all the teeth on one side first, then turn the chain saw and file the teeth on the other side.File all the teeth to the same length. When the length of the cutting teeth is reduced to 5/32 inch (4 mm) the chain is worn out and should be replaced. (10) WARNING Faulty cutting equipment or the wrong combination of bar and saw chain increases the risk of kickback Only use the bar/saw chain combinations we recommend, and follow the filing instructions. See instructions under the heading Technical data.IMPORTANT No saw chain design eliminates the danger of kickback. WARNING Any contact with a rotating saw chain can cause extremely serious injuries. WARNING Always wear gloves, when working with the chain, in order to protect your hands from injury. WARNING Departure from the sharpening instructions considerably increases the risk of kickback.GENERAL SAFETY PRECAUTIONSEnglish – 131154657-49 Rev.5 2013-12-10General advice on adjusting depth gauge setting• When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease. To maintain optimal cutting performance the depth gauge (B) has to be filed down to achieve the recommended depth gauge setting. See instructions under the heading Technical data to find the correct depth gauge setting for your particular chain.Adjustment of depth gauge setting• The cutting teeth should be newly sharpened before adjusting the depth gauge setting. We recommend that you adjust the depth gauge setting every third time you sharpen the cutting teeth. NOTE This recommendation assumes that the length of the cutting teeth is not reduced excessively.• You will need a flat file and a depth gauge tool. We recommend that you use our depth gauge tool to acheive the correct depth gauge setting and bevel for the depth gauge.• Place the depth gauge tool over the chain. Detailed information regarding the use of the depth gauge tool, will be found on the package for the depth gauge tool. Use the flat file to file off the tip of the depth gauge that protrudes through the depth gauge tool. The depth gauge setting is correct when you no longer feel resistance as you draw the file along the depth gauge tool.Tensioning the chainThe more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.Check the chain tension every time you refuel. NOTE A new chain has a running-in period during which you should check the tension more frequently.Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand. (13)• Switch the engine off. (28)• Undo the bar nuts that hold the clutch cover/chain brake. Use the combi-tool integrated in the rear handguard or one with corresponding dimensions (contact your servicing dealer (retailer) for a replacement tool). Then tighten the barnuts by hand as tight as you can. (6) (11)• Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combi-tool. Tighten the chain until it does not sag from the underside of the bar. (12)• Use the combi-tool to tighten the bar nuts while lifting the tip of the bar at the same time. Check that you can pull the chain round freely by hand and that it does not sag from the underside of the bar. (13)Lubricating cutting equipmentChain oilChain oil must demonstrate good adhesion to the chain and also maintain its flow characteristics regardless of whether it is warm summer or cold winter weather.Never use waste oil Using waste oil can be dangerous to you and damage the machine and environment.Filling with chain oil• All our chain saws have an automatic chain lubrication system. On some models the oil flow is also adjustable.• The saw chain oil tank and the fuel tank are designed so that the fuel runs out before the saw chain oil.However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburetor as recommended (a lean mixture may mean that the fuel lasts longer than the oil) and that you also use the recommended cutting equipment (a bar that is too long will use more chain oil).Checking chain lubrication• Check the chain lubrication each time you refuel. See instructions under the heading Lubricating the bar tip sprocket.Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.If the chain lubrication is not working:• Check that the oil channel in the bar is not obstructed. Clean if necessary. WARNING The risk of kickback is increased if the depth gauge setting is too large WARNING A slack chain may jump off the bar and cause serious or even fatal injury. WARNING Always wear approved protective gloves. Even a non-moving chain can cause serious cuts to yourself or persons you bump into with an exposed chain. WARNING Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries.IMPORTANT When using vegetable based saw chain oil, dismantle and clean the groove in the bar and saw chain before long-term storage. Otherwise there is a risk of the saw chain oil oxidizing, which will result in the saw chain becoming stiff and the bar tip sprocket jamming. GENERAL SAFETY PRECAUTIONS14 – English 1154657-49 Rev.5 2013-12-10• Check that the groove in the edge of the bar is clean. Clean if necessary.• Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary.If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer.Chain drive sprocketThe clutch drum is fitted with a Spur sprocket (the chain sprocket is welded on the drum (D)). (4)Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive. Replace the drive sprocket whenever you replace the chain.Checking wear on cutting equipmentCheck the chain daily for:• Visible cracks in rivets and links.• Whether the chain is stiff.• Whether rivets and links are badly worn.Replace the saw chain if it exhibits any of the points above.We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn.When the length of the cutting teeth has worn down to only 5/32 inch (4 mm) the chain must be replaced. (10)Guide barCheck regularly:• Whether there are burrs on the edges of the bar (A). Remove these with a file if necessary. (14)• Whether the groove in the bar has become badly worn (B). Replace the bar if necessary. (14)• Whether the tip of the bar is uneven or badly worn. If a hollow forms on the underside of the bar tip this is due to running with a slack chain.• To prolong the life of the bar you should turn it over daily. WARNING Most chain saw accidents happen when the chain touches the operator.Wear personal protective equipment. See instructions under the heading ”Personal protective equipment”.Do not tackle any job that you feel you are not adequately trained for. See instructions under the headings Personal protective equipment, How to avoid kickback, Cutting equipment and General working instructions.Avoid situations where there is a risk of kickback. See instructions under the heading Machine''''s safety equipment.Use the recommended protective equipment and check its condition. See instructions under the heading General working instructions.Check that all the chain saw safety features are working. See instructions under the headings General working instructions and General safety precautions.ASSEMBLYEnglish – 151154657-49 Rev.5 2013-12-10Fitting the bar and chainCheck that the chain brake is in disengaged position by moving the front hand guard towards the front handle. (24)Undo the bar nuts that hold the clutch cover/chain brake. Use the combi-tool integrated in the rear handguard or one with corresponding dimensions (contact your servicing dealer (retailer) for a replacement tool). Take off the transportation ring (A). (6) (15)Fit the bar over the bar bolts. Place the bar in its rearmost position. Place the chain over the drive sprocket locate it in the groove on the bar. Begin on the top edge of the bar. Make sure that the edges of the cutting links are facing forward on the top edge of the bar. (16)Fit the clutch cover (chain brake) and locate the chain adjuster pin in the cut-out in the bar. Check that the drive links of the chain fit correctly on the drive sprocket and that the chain is in the groove on the bar. Tighten the bar nut finger-tight. (16)Tension the chain by turning the chain tensioning screw clockwise using the combi-tool. The chain should be tensioned until it does not sag from the underside of the bar. (12)The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combi-tool. (13)When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life. WARNING Switch off the engine before carrying out any checks or maintenance. The stop switch automatically returns to the start position. In order to prevent unintentional starting, the spark plug cap must be removed from the spark plug when assembling, checking and/or performing maintenance. Always wear gloves, when working with the chain, in order to protect your hands from injury.FUEL HANDLING16 – English 1154657-49 Rev.5 2013-12-10FuelNote The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.Gasoline• Use good quality unleaded gasoline.• The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage.• When working with continuous high revs (e.g. limbing) a higher octane is recommended.Running-inAvoid running at a too high speed for extended periods during the first 10 hours.Two-stroke oil• For best results and performance use synthetic two-stroke engine oil, which is specially formulated for air-cooled two-stroke engines.• Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).• Never use oil intended for four-stroke engines.Mixing ratio50:1 (2%) for all engines.Mixing• Always mix the gasoline and oil in a clean container intended for fuel.• Always start by filling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline.• Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank.• Do not mix more than one month’s supply of fuel at a time.• If the machine is not used for some time the fuel tank should be emptied and cleaned.Chain oil• We recommend the use of special oil (chain oil) with good adhesion characteristics.• Never use waste oil. This results in damage to the oil pump, the bar and the chain.• It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature.• In temperatures below 32°F (0°C) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components.• Contact your service agent when choosing chain oil.FuelingClean the area around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel filter must be replaced at least once a year. Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before refuelling. The capacities of the chain oil tank and fuel tank are carefully matched. You should therefore always fill the chain oil tank and fuel tank at the same time.

Wipe off the spillage and allow remaining fuel to evaporate.2 If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.3 If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.Transport and storage• Always store the chain saw and fuel so that there is no risk of leakages or fumes coming into contact with sparks or naked flames from electrical equipment, electric motors, relays/switches, boilers and the like.• Always store fuel in an approved container designed for that purpose.• For longer periods of storage or for transport of the chain saw, the fuel and chain oil tanks should be emptied. Ask where you can dispose of waste fuel and chain oil at your local gas station.• Ensure the machine is cleaned and that a complete service is carried out before long-term storage.• The guide bar cover must always be fitted to the cutting attachment when the machine is being transported or in storage, in order to prevent accident contact with the sharp chain. Even a non-moving chain can cause serious cuts to yourself or persons you bump into with an exposed chain.• Secure the machine during transport.Long-term storageEmpty the fuel/oil tanks in a well ventilated area. Store the fuel in approved cans in a safe place. Fit the guide bar cover. Clean the machine. See instructions under the heading Maintenance schedule. WARNING Fuel and fuel vapor are highly flammable. Take care when handling fuel and chain oil. Be aware of the risks of fire, explosion and those associated with inhalation. WARNING Never use a machine with visible damage to the spark plug guard and ignition cable. A risk of sparking arises, which can cause a fire.STARTING AND STOPPING18 – English 1154657-49 Rev.5 2013-12-10Starting and stoppingCold engineStarting: The chain brake should be activated when starting the chain saw. Activate the chain brake by pushing the front hand guard forwards. (26)Air purge: Press the air purge repeatedly until fuel begins to fill the bulb. The bulb need not be completely filled. (20)Choke: Pull the blue choke/fast idle lever out to the full extent (to the FULL CHOKE position). When the choke/fast idle lever is pulled out to the full extent, the correct throttle setting is set automatically. (18)Start throttle: The correct choke/start throttle setting is obtained by moving the control to the choke position. (19)StartingGrip the front handle with your left hand. Hold the chain saw on the ground by placing your right foot through the rear handle. (22)Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull firmly and rapidly until the engine starts. Never wrap the starter cord around your handCAUTION Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.Push in the choke control to the ”HALF choke” setting as soon as the engine fires which can be heard through a "puff" sound. (18)Keep on pulling the cord powerfully until the engine starts. As the chain brake is still engaged the speed of the engine must be set to idling as soon as possible, this is achieved by quickly pressing the throttle trigger once. This prevents unnecessary wear to the clutch, clutch drum and brake band. (23)Note Reactivate the chain brake by pulling the front hand guard back (marked ”PULL BACK TO RESET”) towards the front handle. The chain saw is now ready for use. (24)There is a simplified start reminder with illustrations to describe each step on the rear edge of the saw.Warm engineUse the same procedure as for starting a cold engine but without setting the choke control in the choke position. Set the throttle to the start position by pulling out the blue choke control to the choke position and then pushing it in again. (21)• Never start a chain saw unless the bar, chain and all covers are fitted correctly. See instructions under the heading Assembly. Without a bar and chain attached to the chain saw the clutch can come loose and cause serious injury. (25)• The chain brake should be activated when starting. Se instructions under the heading Start and stop. Do not drop start. This method is very dangerous because you may lose control of the saw. (26)• Never start the machine indoors. Exhaust fumes can be dangerous if inhaled.• Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment.• Always hold the saw with both hands. The right hand should be on the rear handle, and the left hand on the front handle. All people, whether right or left handed, should use this grip. Use a firm grip with thumbs and fingers encircling the chain saw handles. (27)StoppingStop the engine by pressing down the stop button. (28) WARNING Note the following before starting:The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting. Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the clutch can come loose and cause personal injuries.Place the machine on firm ground. Make sure you have a secure footing and that the chain cannot touch anything.Keep people and animals well away from the working area. WARNING Long term inhalation of the engine’s exhaust fumes, chain oil mist and dust from sawdust can represent a health risk.WORKING TECHNIQUESEnglish – 191154657-49 Rev.5 2013-12-10Before use: (29)1 Check that the chain brake works correctly and is not damaged.2 Check that the rear right hand guard is not damaged.3 Check that the throttle lockout works correctly and is not damaged.4 Check that the stop switch works correctly and is not damaged.5 Check that all handles are free from oil.6 Check that the anti vibration system works and is not damaged.7 Check that the muffler is securely attached and not damaged.8 Check that all parts of the chain saw are tightened correctly and that they are not damaged or missing.9 Check that the chain catcher is in place and not damaged.10 Check the chain tension.General working instructionsBasic safety rules1 Look around you:• To ensure that people, animals or other things cannot affect your control of the machine.• To make sure that none of the above might come within reach of your saw or be injured by falling trees.CAUTION Follow the instructions above, but do not use a chain saw in a situation where you cannot call for help in case of an accident.2 Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc.3 Take great care when removing small branches and avoid cutting bushes (i.e. cutting many small branches at the same time). Small branches can be grabbed by the chain and thrown back at you, causing serious injury.4 Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.5 Take great care when cutting a tree that is under tension. A tree that is under tension may spring back to its normal position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury.6 Before moving your chain saw switch off the engine and lock the chain using the chain brake. Carry the chain saw with the bar and chain pointing backwards. Fit a guard to the bar before transporting the chain saw or carrying it for any distance.7 When you put the chain saw on the ground, lock the saw chain using the chain brake and ensure you have a constant view of the machine. Switch the engine off before leaving your chain saw for any length of time.General rules1 If you understand what kickback is and how it happens then you can reduce or eliminate the element of surprise. By being prepared you reduce the risk. Kickback is usually quite mild, but it can sometimes be very sudden and violent.2 Always hold the chain saw firmly with your right hand on the rear handle and your left hand on the front handle. Wrap your fingers and thumbs around the handles. You should use this grip whether you are right-handed or left-handed. This grip minimizes the effect of kickback and lets you keep the chain saw under control. Do not let go of the handles (27)3 Most kickback accidents happen during limbing. Make sure you are standing firmly and that there is nothing in the way that might make you trip or lose your balance.Lack of concentration can lead to kickback if the kickback zone of the bar accidentally touches a branch, nearby tree or some other object.Have control over the workpiece. If the pieces you intend to cut are small and light, they can jam in the saw chain and be thrown towards you. This is not necessarily dangerous in itself, but you may be surprised and lose control of the saw. Never saw IMPORTANTThis section describes basic safety rules for using a chain saw. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsafe, stop and seek expert advice. Contact your chain saw dealer, service agent or an experienced chain saw user. Do not attempt any task that you are not sure you can handleBefore using a chain saw you must understand the effects of kickback and how to avoid them. See instructions under the heading How to avoid kickback.Before using a chain saw you must understand the difference between cutting with the top and bottom edges of the bar. See instructions under the headings How to avoid kickback and Machine’s safety equipment.Wear personal protective equipment. See instructions under the heading ”Personal protective equipment”. WARNING Sometimes chips get stuck in the clutch cover causing the chain to jam. Always stop the engine before cleaning.WORKING TECHNIQUES20 – English 1154657-49 Rev.5 2013-12-10stacked logs or branches without first separating them. Only saw one log or one piece at a time. Remove the cut pieces to keep your working area safe.4 Never use the chain saw above shoulder height and avoid cutting with the tip of the bar. Never use the chain saw one-handed (30)5 In order to keep control of your saw, always maintain a firm foothold. Never work on a ladder, in a tree or on any other insecure support. (31)6 Always use a fast cutting speed, i.e. full throttle.7 Take great care when you cut with the top edge of the bar, i.e. when cutting from the underside of the object. This is known as cutting with a pushing chain. The chain tries to push the chain saw back towards the user. If the saw chain is jamming, the saw may be pushed back at you.8 Unless the user resists this pushing force there is a risk that the chain saw will move so far backwards that only the kickback zone of the bar is in contact with the tree, which can lead to a kickback. (32)Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting with a pulling chain. In this case the chain saw pulls itself towards the tree and the front edge of the chain saw body rests naturally on the trunk when cutting. Cutting with a pulling chain gives the operator better control over the chain saw and the position of the kickback zone.9 Follow the instructions on sharpening and maintaining your bar and chain. When you replace the bar and chain use only combinations that are recommended by us. See instructions under the headings Cutting equipment and Technical data.Basic cutting techniqueGeneral• Always use full throttle when cutting• Reduce the speed to idle after every cut (running the engine for too long at full throttle without any load, i.e. without any resistance from the chain during cutting, can lead to serious engine damage).• Cutting from above = Cutting with a pulling chain.• Cutting from below = Cutting with pushing chain.Cutting with a pushing chain increases the risk of kickback. See instructions under the heading How to avoid kickback.TermsCutting = General term for cutting through wood.Limbing = Cutting branches off a felled tree.Splitting = When the object you are cutting breaks off before the cut is complete.There are five important factors you should consider before making a cut:1 Make sure the cutting equipment will not jam in the cut.2 Make sure the object you are cutting will not split.3 Make sure the chain will not strike the ground or any other object during or after cutting.4 Is there a risk of kickback?5 Do the conditions and surrounding terrain affect how safely you can stand and move about?Two factors decide whether the chain will jam or the object that you are cutting will split: the first is how the object is supported before and after cutting, and the second is whether it is in tension.In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom. You need to support the object so that it will not trap the chain or split during cutting.The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw.LimbingWhen limbing thick branches you should use the same approach as for cutting.Cut difficult branches piece by piece.CuttingIf you have a pile of logs, each log you attempt to cut should be removed from the pile, placed on a saw horse or runners and cut individually.Remove the cut pieces from the cutting area. By leaving them in the cutting area, you increase the risk for inadvertently getting a kickback, as well as increasing the risk of losing your balance while working. WARNING Never use a chain saw by holding it with one hand. A chain saw is not safely controlled with one hand. Always have a secure, firm grip around the handles with both hands.IMPORTANT If the chain jams in the cut: stop the engine Don’t try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw. WARNING Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury.WORKING TECHNIQUESEnglish – 211154657-49 Rev.5 2013-12-10The log is lying on the ground. There is little risk of the chain jamming or the object splitting. However there is a risk that the chain will touch the ground when you finish the cut.Cut all the way through the log from above. Avoid letting the chain touch the ground as you finish the cut. Maintain full throttle but be prepared for what might happen. (33)If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log.Turn the log and finish the cut from the opposite side.The log is supported at one end. There is a high risk that it will split.Start by cutting from below (about 1/3 of the way through).Finish by cutting from above so that the two cuts meet.The log is supported at both ends. There is a high risk that the chain will jam.Start by cutting from above (about 1/3 of the way through).Finish by cutting from below so that the two cuts meet.Tree felling techniqueSafe distanceThe safe distance between a tree that is to be felled and anyone else working nearby is at least 2 1/2 tree lengths. Make sure that no-one else is in this ”risk zone” before or during felling. (39)Felling directionThe aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely.Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally.Several factors affect this:• Lean of the tree• Bend• Wind direction• Arrangement of branches• Weight of snow• Obstacles within the reach of the tree: for example, other trees, power lines, roads and buildings.• Look for signs of damage and rot in the stem, this makes it more probably that the tree will break and start to fall before you expect it to. You may find you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you first intended.Another very important factor, which does not affect the felling direction but does affect your safety, is to make sure the tree has no damaged or dead branches that might break off and hit you during felling.The main point to avoid is letting the tree fall onto another tree. It is very dangerous to remove a trapped tree and there is high accident risk. See instructions under the heading Freeing a tree that has fallen badly.Clearing the trunk and preparing your retreatDelimb the stem up to shoulder height. It is safer to work from the top down and to have the tree between you and the saw. Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall. Your path of retreat should be roughly 135 degrees away from the intended felling direction. (40)FellingFelling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you finish with the felling cut. By placing these cuts correctly you can control the felling direction very accurately.Directional cutsTo make the directional cuts you begin with the top cut. Stand to the right of the tree and cut on the pull stroke.Next make the bottom cut so that it finishes exactly at the end of the top cut. (41)The directional cuts should run 1/4 of the diameter through the trunk and the angle between the top cut and bottom cut should be 45°.The line where the two cuts meet is called the directional cut line. This line should be perfectly horizontal and at right angles (90°) to the chosen felling direction. (42)Felling cutThe felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut on the pull stroke.Make the felling cut about 1.5-2 inches (3-5 cm) above the bottom directional cut.Finish the felling cut parallel with the directional cut line so that the distance between them is at least 1/10 of the trunk diameter. The uncut section of the trunk is called the felling hinge.The felling hinge controls the direction that the tree falls in. (44)IMPORTANT It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task beyond your experience level IMPORTANT During critical felling operations, hearing protectors should be lifted immediately when sawing is completed so that sounds and warning signals can be heard. WARNING Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your sawWORKING TECHNIQUES22 – English 1154657-49 Rev.5 2013-12-10All control over the felling direction is lost if the felling hinge is too narrow or non-existent, or if the directional cuts and felling cut are badly placed.When the felling cut and directional cut are complete the tree should start to fall by itself or with the aid of a felling wedge or breaking bar.We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the felling cut and directional cuts with single cutting strokes. See instructions under the heading Technical data section to find out which lengths of bar are recommended for your saw.There are methods for felling trees with a diameter larger than the bar length. However these methods involve a much greater risk that the kickback zone of the bar will come into contact with the tree.Freeing a tree that has fallen badly Freeing a ”trapped tree”It is very dangerous to remove a trapped tree and there is high accident risk.Never try to fell the tree that is trapped.Never work in the risk zone of the hanging trapped tree.The safest method is to use a winch.• Tractor-mounted• PortableCutting trees and branches that are in tensionPreparations: Work out which side is in tension and where the point of maximum tension is (i.e. where it would break if it was bent even more).Decide which is the safest way to release the tension and whether you are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch.General advice:Position yourself so that you will be clear of the tree or branch when the tension is released.Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufficient depth as necessary to reduce the tension and make the tree or branch break at the point of maximum tension.Never cut straight through a tree or branch that is in tension If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep.Continue to cut deeper until tree/limb bends and tension is released.Cut tree/limb from outside the bend, after tension has been released.How to avoid kickbackWhat is kickback?The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object. (32)Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object.Kickback only occurs if the kickback zone of the bar touches an object. (45)LimbingMake sure that you can stand and move about safely. Work on the left side of the trunk. Work as close as possible to the chain saw for maximum control. If possible, let the weight of the chain saw rest on the trunk.Keep the trunk between you and the chain saw as you move along the trunk.Cutting the trunk into logsSee instructions under the heading Basic cutting technique. WARNING Kickback can happen very suddenly and violently; kicking the chain saw, bar and chain back at the user. If this happens when the chain is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique. WARNING A majority of kickback accidents occur during limbing. Do not use the kickback zone of the guide bar. Be extremely cautious and avoid contacting the log, other limbs or objects with the nose of the guide bar. Be extremely cautious of limbs under tension. They can spring back toward you and cause loss of control resulting in injury.MAINTENANCEEnglish – 231154657-49 Rev.5 2013-12-10GeneralThe user must only carry out the maintenance and service work described in this manual. More extensive work must be carried out by an authorized service workshop.Carburetor adjustmentYour McCulloch product has been designed and manufactured to specifications that reduce harmful emissions.Function• The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine.• The T-screw regulates the throttle setting at idle speed. If the T-screw is turned clockwise this gives a higher idle speed; turning it anti-clockwise gives a lower idle speed.Basic settings and running inThe basic carburetor settings are adjusted during testing at the factory. Fine adjustment should be carried out by a skilled technician.Rec. idle speed: See the Technical data section.Fine adjustment of the idling speed TAdjust the idle speed with the T-screw. If it is necessary to re-adjust, turn the T-screw clockwise while the engine is running, until the chain starts to rotate. Then turn counter-clockwise until the chain stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the chain starts to rotate.Checking, maintaining and servicing chain saw safety equipmentChain brake and front hand guardChecking brake band wearBrush off any wood dust, resin and dirt from the chain brake and clutch drum. Dirt and wear can impair operation of the brake. (34)Regularly check that the brake band is at least 0.024 inch (0,6 mm) thick at its thinnest point.Checking the front hand guardMake sure the front hand guard is not damaged and that there are no visible defects such as cracks.Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover. (35)Checking the inertia brake releaseWith the engine turned off, hold the chain saw over a stump or other firm object. Let go of the front handle so that the bar drops towards the stump as the chain saw rotates around the rear handle.When the bar hits the stump the brake should be activated. (37)Checking the brake triggerPlace the chain saw on firm ground and start it. Make sure the chain does not touch the ground or any other object. See the instructions under the heading Start and stop.Grasp the chain saw firmly, wrapping your fingers and thumbs around the handles.Apply full throttle and activate the chain brake by tilting your left wrist forward onto the front hand guard. Do not let go of the front handle. The chain should stop immediately.Throttle lockout• Make sure the throttle control is locked at the idle setting when the throttle lockout is released.• Press the throttle lockout and make sure it returns to its original position when you release it.• Check that the throttle trigger and throttle lockout move freely and that the return springs work properly. WARNING Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the chain stops at idle. Do not use the chain saw until it has been properly adjusted or repaired.Note All servicing and repair work on the machine requires special training. This is especially true of the machine's safety equipment. If your machine fails any of the checks described below we recommend you to contact our servicing dealer. Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).Switch off the engine and take off the ignition cable before repairs or maintenanceMAINTENANCE24 – English 1154657-49 Rev.5 2013-12-10• Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburetor idle adjustment.Chain catcherCheck that the chain catcher is not damaged and is firmly attached to the body of the chain saw.Right hand guardCheck that the right hand guard is not damaged and that there are no visible defects, such as cracks.Vibration damping systemRegularly check the vibration damping units for cracks or deformation.Make sure the vibration damping units are securely attached to the engine unit and handle unit.Stop switchStart the engine and make sure the engine stops when you move the stop switch to the stop setting. (28)MufflerNever use a machine that has a faulty muffler. Regularly check that the muffler is securely attached to the machine.Note: The spark arrestor screen (A) on this machine is serviceable. The screen must be replaced if it is damaged. If the screen is blocked the machine will overheat and this will cause damage to the cylinder and piston. Never use a machine with a muffler that is in poor condition. Never use a muffler if the spark arrestor screen is missing or defective. (7)After 75 hours of use, we recommend that your muffler be replaced by your servicing dealer (retailer).Air filterThe air filter must be regularly cleaned to remove dust and dirt in order to avoid:• Carburettor malfunctions• Starting problems• Loss of engine power• Unnecessary wear to engine parts• Excessive fuel consumption.• Remove the air filter (3) after taking off the cylinder cover, screw (1) and filter cover (2). When refitting make sure that the air filter seals tightly against the filter holder. Clean the filter by brushing or shaking it. (36)The filter can be cleaned more thoroughly by washing it in water and detergent.An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced.Spark plugThe spark plug condition is influenced by:• Incorrect carburetor adjustment.• An incorrect fuel mixture (too much or incorrect type of oil).• A dirty air filter.These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties. (38)If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0,5 mm). The spark plug should be replaced after about a month in operation or earlier if necessary.Note Always use the recommended spark plug type Use of the wrong spark plug can damage the piston/cylinder. Check that the spark plug is fitted with a suppressor.”CCS” centrifugal cleaningCentrifugal cleaning means the following: All air to the carburetor passes through the starter. Dirt and dust is pushed out by the cooling fan.IMPORTANT In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the fins on the flywheel, the space around the flywheel, inlet pipe and carburetor compartment.English – 25MAINTENANCE1154657-49 Rev.5 2013-12-10Maintenance scheduleThe following is a list of the maintenance that must be performed on the machine.

Sudden surprise contributes to accidents.Keep a good firm grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don’t let go.Make sure that the area in which you are cutting is free from obstacles. Do not let the nose of the guide bar contact a log, branch, or any other obstacle which could be hit while you are operating the saw.Cut at high engine speeds.Do not overreach or cut above shoulder height.Follow manufacturer’s sharpening and maintenance instructions for the saw chain.Only use replacement bars and chains specified by the manufacturer or the equivalent.Other safety precautionsDo not operate a chain saw when you are fatigued.Use safety footwear; snug-fitting clothing, protective gloves, and eye, hearing and head protection devices.Use caution when handling fuel. Move the chain saw at least 10 feet (3 m) from the fueling point before starting the engine.Do not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.Do not start cutting until you have a clear work area, secure footing and a planned retreat path from the falling tree.Keep all parts of your body away from the saw chain when the engine is running.Before you start the engine, make sure that the saw chain is not contacting anything.Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.Shut off the engine before setting the chain saw down.Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.When cutting a limb that is under tension be alert for springback so that you will not be struck when the tension in the wood fibers is released.Keep handles dry, clean and free of oil or fuel mixture.Operate the chain saw only in well-ventilated areas.Do not operate a chain saw in a tree unless you have been specifically trained to do so.Do not operate a chain saw above shoulder height.All chain saw service, other than the items listed in the operator’s/owner’s safety and maintenance instructions, should be performed by competent chain saw service personnel. (For example, if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and subsequently cause the flywheel to burst.)When transporting your chain saw, use the appropriate guide bar guard.Note: This Annex is intended primarily for the consumer or occasional user. WARNING Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.Tip contact in some cases may cause a lightning fast reverse reaction, kicking the guide bar up and back towards the operator.Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.Either of these reactions may cause you to lose control of the saw which could result in serious personal injury.Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. WARNING Do not operate a chain saw with one hand Serious injury to the operator, helpers, bystanders or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use.INTRODUCTIONFrench – 311154657-49 Rev.5 2013-12-10Cher client,Nous vous remercions d’avoir choisi un produit McCulloch Vous faites désormais partie d’une histoire débutée il y a longtemps, lorsque l’entreprise McCulloch commença à fabriquer des moteurs pendant la Seconde Guerre mondiale. En 1949, McCulloch lançait sa première tronçonneuse légère à utilisateur unique et révolutionnait le travail du bois à tout jamais.La gamme de tronçonneuses innovantes allait se développer au fil des décennies et les activités se diversifier, d’abord avec des moteurs d’avion et de kart dans les années 1950, puis avec des mini-tronçonneuses dans les années 1960. Plus tard, dans les années 1970 et 1980, les coupe-herbes et aspiro-souffleurs venaient compléter la gamme.Aujourd’hui, McCulloch a rejoint le groupe Husqvarna et poursuit la tradition de moteurs puissants, d’innovations techniques et de conceptions résistantes, nos marques de fabrique depuis plus d’un siècle. La réduction de la consommation en carburant, des émissions et des niveaux sonores est notre priorité, tout comme l’amélioration de la sécurité et de la convivialité du produit.Nous espérons que ce produit McCulloch vous donnera toute satisfaction et qu’il vous accompagnera pendant de longues années.
