9.4 CUTTING BLADE

WARNING: Be sure to disconnect 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.
According to the instructions in the separate engine manual, tilt the mower (unless otherwise stated,
lift it up so that the spark plug is at the top). 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.
Fig. 12
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 re-sharpened 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 remounting blade and blade adapter on the mower lubricate the crankshaft and the inner
surface of the blade adapter with light oil. Install the blade adapter on the crankshaft. Refer to figure
12. Place the blade with the part number facing away from the adapter. Align the washer over the
blade and insert the hex bolt. Bolt tightening torque of 40-50 Nm.
Possible damage resulting from blade unbalance condition is not the responsibility of the
manufacturer.
After prolonged use, especially in sandy soil conditions, the blade will become worn and lose some of
the original shape. Cutting efficiently will be reduced and the blade should be replaced.
When you change the blade, use the original type marked on the blade (26300100401). For order the
blade, pls. contact your local dealer.
WARNING: Do not touch rotating blade.
