9.1.1 To clean air filter

4 Air dry filter element.
5 Place a few drops of SAE30 oil on the foam filter and squeeze tightly to remove any

9.2 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.
