The minimum mowing height with respect to each bottom blade thickness is shown below. ? The minimum mowing height is the height on the average condition green. Lawn maybe shaved when the undulation of the green is substantial. Set the mowing heighthigher in that case.2) Adjust the front gloomer according to the condition of the green before use.? If the groomer blades are set deeper than the ground surface, the shaft may bend.? The front groomer, when it is put too low, will apply an excessive load to the engineand transmission section, causing malfunction or failure.3) When using the grooming brush, adjust the height so that it will be equal to the mowing height.? The brush will be worn easily when the height is too low.4)[IMPORTANT] Adjustment of front roller heightBring the mowing height gauge into contact with the front roller and drum (as shownbelow), and adjust the height of the bottom blade.a. Loosen the tall nut of the roller bracket, and move the front roller up or down withroller adjuster.b. Position the front roller with the mowing height gauge.c. Make adjustment at both edges.d.

Blade engagementCheck that the engine is at rest before making adjustment. Grind and adjust the blade reel cylinder and bottom blade entirely so that anewspaper will be cut sharply.[IMPORTANT] LappingConduct lapping after mowing operation (before adjusting the engagement).1) Check the entire portion of the blade reel cylinder to check which portion is dull. (If a newspaper cannot be cut in any portion, put in two sheets of paper to carefully checkwhich portion is dull.)2) Connect the lapping machine (RM20B) or lapping bolt (option) to the lapping shaft of the mower.3) Rotate the blade reel cylinder in the direction opposite to the mowing direction, and apply abrasive with a brush only to the portion where a newspaper was sharply cut.The portion where a newspaper was not cut is worn away. Do not apply abrasive tosuch portions.?The right side (when viewed from the front of the blade reel cylinder) of the blade reel cylinder will be worn away 3-4 times earlier than the left side. When applyingabrasive to the blade reel cylinder, be sure to move the brush from left to right. (Seeright sketch)When the abrasive is a mixture of powder (#200~#400) and oil, mixthem at the rate of 1:3 to 4. The gel compound (option) can be used as it is.4) Keep rotating the blade reel cylinder, and stop rotation when the contact sound disappears. Put in a newspaper again to check the blade reel cylinder entirely for thesharpness of each portion.5) Repeat operations (3) and (4). When the blade reel cylinder and bottom blade are in contact with each other uniformly, apply abrasive to the blade reel cylinder entirely forfinal lapping.6) After lapping, remove the abrasive with steam, etc.Both blade reel cylinder and bottom blade are edged. Handle themcarefully.Be careful of the fingers, which turn the blade reel cylinder, whencutting a newspaper to check sharpness. Uniformly lap the right andleft sides of the bottom blade in contact with the blade reel cylinder, andthe life of the blade will be maximized.6-1[IMPORTANT]Engagement1) Lightly engage the blade reel cylinder and bottom blade uniformly on both sides.2) Uniformly adjust the bottom blade on the right and left sides. Turn the blade adjusting nut clockwise for slight engagement, and turn itcounterclockwise for firm engagement.3) Lightly engage both sides to the extent that a newspaper will be cut sharply.When the blade reel cylinder is worn and the spring pressure decreases, adjust thespring pressure by the spring adjusting screw and 14 nut. (Make adjustment so thatthe spring will be 50 mm long.)[IMPORTANT] Cam adjustmentTurn the cam bush on both sides of the bottom blade, and the blade will be raised andlowered within a maximum range of 0.3 mm. The above method is used when the edgesof the blade reel cylinder and bottom blade are not in parallel.1) When there is a gap between the blade reel cylinder and the left frame side of the bottom blade loosen the lock nut, and turn the left cam bush clockwise as much as thegap. Turn it clockwise by 30°to raise the bottom blade by 0.1 mm. After adjustment,firmly fasten the lock nut.2) When there is a gap on the right frame side, loosen the lock nut, and turn the right cam bush counterclockwise as much as the gap.6-26-3CAUTIONMove the brushfrom left to rightSpring length50mm Blade adjusting nut14Cylindrical grinding and installation of blade reel cylinderCylindrically grind the blade reel cylinder when it is worn away and has become conical.(Ask the dealer you purchased the machine from for cylindrical grinding.)

(Replace them even if they have not been used for many hours.)4)Clean the machine, and apply grease or oil to respective sliding sections.15Machine number plate attaching positionThe type and serial number are marked on the machine number plate.It is attached to the upper portion on the left side of the front frame stay.6-86-96-10Qty of engine oilPlugCapacity of gasoline tankTire air pressureEngine speed0.6dm3(0.6L)NGK BR4HS2.5dm3(2.5L)120kpa(1.2kg/cm2)1400~3400rpmMachine number plateAttaching/detaching the bottom blade baseRemove the bottom blade base arm, and then remove the bottom blade base.Attach the bottom blade base, and then attach the bottom blade base arm.6-7Bottom blade base armBottom blade base armLoosen.Tighten.Bottom blade baseLoosen.Tighten.Loosen.Tighten.9) When the machine is to be stored for a long time exceeding 5 months, remove gasoline from the engine.10) Engine maintenance scheduleTo keep the engine in satisfactory status at all times, be sure toconduct maintenance and inspection according to the followingtable:9.Maintenance Schedule8. Precautions for engine operationFor the engine, refer to the engine operation manual.1) Use gasoline for automobiles as the fuel of the engine.2) Completely change engine oil when the machine has been used for eight hours after the initial operation, because the machine is usedunder tough conditions with vibration and dust, and change oil every50 hours after that. The quantity of engine oil is 0.6 dm3 (0.6L). UseSAE30.3) Always cover the suction port of the air cleaner with a cleaner cover bag during operation. Be sure to clean the air cleaner elementbefore using the machine.4) Fire is strictly prohibited during fuel supply. Be careful of a lit cigarette. Replenish the fuel tank outdoors after the stopped enginehas been cooled. Wipe off the spilt fuel completely.5) Do not start the engine in a building without a proper ventilator.6) The muffler and the area around the exhaust port of the muffler will become hot. Do not bring gasoline, matches, dry grass, or otherinflammables near hot portions.7) Inspection before operationCheck the joint of fuel pipe, etc. for looseness or damage. Checkbolts and nuts in respective sections for looseness.8) Wear appropriate clothes. An apron, towel on the belt, long string,etc. will cause you to be caught in rotating parts.DANGERCAUTIONCAUTIONCAUTIONCAUTIONEngineMaintenanceCleaning of each part/inspection of tighteningInspection and addition of fuelInspection and cleaning of air cleanerInspection and addition of engine oilEngine oil changeMain unitMaintenanceInspection and cleaning of recoil starter dust proofing netCleaning of each part/inspection of tighteningInspection and adjustment of blade engagementInspection and adjustment of mowing heightGreasing and oilingRemoval of mown grass and dustBefore use?????????Every 8hrEvery 8hrEvery 10hrEvery 10hr?Every 50hr?Every 50hr?16only after theinitial operation17Location of Labels for LM56GA and LM66TA123456789101112Code No. Part Name Qty/UnitCode No. Part NameClutch MarkEngine oil Warning MarkNoise Warning MarkLWA 98 MarkClutch Mark (Large)"Handle with care" label"Cutting Warning" labelGroomer Mode SelectorGrease Up 10h MarkBRAKE MarkWarning MarkK4203001040K4205001300K4205001330K4209000880K4203001110K4205001590K4205001600K4203001120K4209000370K4203000970R073-20051-811111111121143 5Right-side of the main unitRear of the main unit1218?Use only unleaded gasoline.?Read the owner's manual.?keep a safe distance from themachine.?Do not open or remove safetyshields while engine isrunning.?Stop the engine and wait formoving parts to stop.?It is strongly advised that theoperators of this machine wear eardefenders for their protection.?Stay clear of the hot surface.?Exhaust gas is poisonous.Do not operate in an unventilatedarea.?Stop the engine before refueling.?Fire, open flame and smokingprohibited.Understanding the machine safety labels??????? ? ?? ?
