Tightening torquesStandard tightening torquesBolts and Nuts
Important
A number of bolts are used in each part of this machine.Be sure to re-tighten the bolts and nuts, because they may be loosened at the earlier stage of theuse.
As to the bolts and nuts without any special instruction, tighten them in appropriate tightening torquewith proper tool.Too much tightening may cause the looseness or damage of the screw.The strength of tightening is determined by types of screws, strength, the friction of thread face orbase face and others.The table below is for the galvanized or parkerized bolts.In case that the strength of internal thread is weak, it is not applied.Do not use rusty or sand attached "screw."Otherwise, it may cause insufficient tightening even if you apply the specified tightening torque.The friction of the screw face becomes higher and the tightening torque is canceled out by thefriction, therefore sufficient tightening cannot be applied.If "screw" is wet by water or oil, do not tighten it with normal tightening torque.If the screw is wet, the torque coefficient will get smaller and it may result in too much tightening.Too much tightening may cause looseness by the screw stretched or result in damage.Do not use a bolt experienced too much burden.Using the impact wrench requires the skill.Do exercise as much as possible for steady tightening.

With the cutter adjustment nut, adjust theengagement between the reel cutter (cuttingcylinder) and the bed knife (bottom blade) sothat newspaper (one sheet) will be cleanlycut by the edge of both blades when theblades in their entirety come slightly intocontact with each other.Insert a strip of newspaper into the spacebetween the reel cutter (cutting cylinder) andthe bed knife (bottom blade) at an angle of90 degrees. Then, rotate the reel cutter(cutting cylinder) counter-clockwise (whenyou face the mower unit from the left) tocheck the sharpness of the blades.Check the sharpness of the entire range (atthree or four points between the left and rightends) of the reel cutter (cutting cylinder).
If there is a gap between the blade edges:Loosen (rotate counter-clockwise) thecutter adjustment nut to apply morecontact pressure between the reel cutter(cutting cylinder) and the bed knife(bottom blade).If the reel cutter (cutting cylinder) is tootight to turn:Tighten (rotate clockwise) the cutteradjustment nut to reduce the contactpressure between the reel cutter (cuttingcylinder) and the bed knife (bottom blade).If the blades still cannot cut well:Perform back lapping of the reel cutter(cutting cylinder).

Adjustment of GroomerNote:Depending on the specifications, this functionmay not be available.
Important
If the front groomer is being used, adjust itaccording to the conditions of the greens.
Important
Set the grooming height more than 0.0 mmfrom the ground.Allowing the front groomer to go into theground may damage the groomer shaft.
Important
If the front groomer goes in too deep, theengine and drive components may becomeoverloaded, which may cause malfunction anddamage.
Important
When using the grooming brush, adjust it tothe same height as the cutting height.If the grooming brush is too low, it may quicklybecome damaged.
Set the slide caliper to the required cuttingheight, adjust the position of the bottom ofthe head of the small screw for groomer inthe cutting height gauge, and then securelylock it with a fly nut.

IGCA (Independent Grass Catcher Arm)Note:Depending on the specifications, this functionmay not be available.(IGCA can be installed onto the LM18GC/LM56GC.)IGCA is located above the mower.The IGCA is a mechanism that prevents themowing attitude of the mower from changing,even when there is an increase in the volumeof clippings entering the grass catcher.It eliminates as much as possible the transferof rough handle movements causing changesin the mower's attitude.Since the mower is stabilized while the lawn ismowed, even if the handle is treated roughly,the cutting height does not change from thestart of mowing the green to the end.Stable lawn mowing work can be performedregardless of the operator's skill level andmachine proficiency level, enabling all greensto be mowed at a uniform cutting height.

Issue 1:The cutting height fluctuates due to the up-and-down movements of the mower causedby the weight of the grass catcher.
Solution:The mower and grass catcher operateindependently.Therefore, the mowing attitude of themower is not affected, even when thegrass catcher becomes heavier from theadded weight of grass, thatch, sand, etc.The operator can mow at a uniform cuttingheight from the start of mowing the greento the end.

Issue 2:The cutting height is uneven due to the up-and-down movements of the mower causedby the operator's handle movements.
Solution:The grass catcher and handle are linked,eliminating as much as possible thetransfer of rough handle movementscausing changes in the mower's attitude.By adjusting the link rods, the handle canremain centered in the handle adjuster,and uniform mower contact pressure canbe achieved.

Back Lapping of Reel Cutter (CuttingCylinder)
Back lapping is work similar to sharpening acooking knife. If the edges of the reel cutter(cutting cylinder) and the bed knife (bottomblade) become blunt and make cutting difficult,both the reel cutter (cutting cylinder) and thebed knife (bottom blade) should besimultaneously sharpened by reversing the reelcutter (cutting cylinder) with an abrasive pasteapplied.However, back lapping is a temporary measureand would not restore the sharpnesscompletely.If the edges of the reel cutter (cutting cylinder)and the bed knife (bottom blade) become bluntand make cutting difficult, follow the stepsbelow to perform back lapping.
Caution
Both the reel cutter (cutting cylinder) and thebed knife (bottom blade) are edged tools.Handle them carefully, since they could cutyour hands and feet.
Caution
During back lapping, the reel cutter (cuttingcylinder) rotates.Keep hands and feet away from moving parts.
Caution
Do not perform back lapping with any otherpersons.
Have the following items ready: Strips ofnewspaper, Abrasive [Back lapping powdermixed with oil; or gel compound (Baronessgenuine abrasive)], Brush.

Note:The mixing ratio for the abrasive, in volume,is one part back lapping powder (#200 -#400) to three or four parts oil.Have a lapping machine or the lappinghandle ready.
Caution
When handling the reel cutter (cuttingcylinder) or bed knife (bottom blade), weargloves to protect your hands.However, pay attention not to let the reelcutter (cutting cylinder) catch your gloves, etc.Otherwise, you may injure your hand orfingers.

Sharpening of Reel Cutter (CuttingCylinder)
Caution
Both the reel cutter (cutting cylinder) and thebed knife (bottom blade) are edged tools.Handle them carefully, since they could cutyour hands and feet.
Caution
Wear gloves when touching edged tools toavoid cutting your hands.
The sharpening of the reel cutter (cuttingcylinder) consists in maintaining its roundnessand creating a relief (second edge face).This work should be performed if thesharpness cannot be restored, even after backlapping, or if the relief (second edge face) hasworn away.Sharpen the reel cutter (cutting cylinder) whenthe sharpness cannot be restored, even afterback lapping, or when the relief (second edgeface) has worn away, there is full contact orback lapping takes too much time.In addition, if the reel cutter (cutting cylinder)becomes worn and its shape conical, performcylindrical grinding to return it to a cylindricalshape.
