10.2 CUTTING BLADE

CAUTION: Be sure to disconnect and ground the spark plug wire before working on the cutting blade to
prevent accidental engine starting. Protect hands by using heavy gloves or a rag to grasp the cutting
blades .Tip mower as specified in separate engine manual. Remove the hex bolt and washer which hold the
blade and blade adapter to the engine crankshaft. Remove the blade and adapter from the crankshaft.
WARNING: Periodically inspect the blade adapter for cracks, especially if you strike a foreign object.
Replace when necessary.
For best results your blade should be sharp. The blade may be resharpened by removing it and either
grinding or filing the cutting edge keeping as close to the original bevel as possible. It is extremely important
that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade. Improper blade
balance will result in excessive vibration causing eventual damage to the engine and mower. Be sure to
carefully balance blade after sharpening. The blade can be tested for balance by balancing it on a round shaft
screwdriver. Remove metal from the heavy side until it balances evenly.
Before reassembling the blade and the blade adapter to the unit, lubricate the engine crankshaft and the inner
surface of the blade adapter with light oil. Insert the key into the blade adapter and Install the blade adapter
on the engine crankshaft, push the washer into the blade adapter and install the blade, Refer to figure 17.
Place the blade with the part number facing away from the adapter. Align the washer over the blade and
insert the hex bolt. Tighten the hex bolt to the torque listed below:

Center Bolt 40Nm-50Nm, to insure safe operation of your unit. ALL nuts and bolts must be checked periodically
for correct tightness.
After prolonged use, especially in sandy soil conditions, the blade will become worn and lose some of the
original shape. Cutting efficiency will be reduced and the blade should be replaced. Replace with an approved
factory replacement blade only. Possible damage resulting from blade unbalance condition is not the
