10.1.1 To clean air filter
 Unclip the air filter cover and remove the sponge filter element. (To avoid objects falling
into the air intake, replace the air filter cover)
 You can use compressed air to dry and clean the air filter.
 Reinstall filter.
NOTE: Replace filter if frayed, torn, damaged or unable to be cleaned.
10.2 Cutting blade (Fig. 15)
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 the mower on its right side (remove the side discharge first!) or to the rear, but not more
than 30 degrees (always keeping the carburettor pointing upwards!).
Do not tilt mower more then 30° towards the rear. If you want to tilt it more,
first drain fuel tank completely (see 9.3).
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 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 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. Install the blade adapter on
the crankshaft with the "star" away from the engine. Place the blade with the label GRASS
SIDE away from the blade holder. Put the ring on the blade and attach the hex bolt. Secure
the hex bolt with the mounting torque as stated below.
10.3 Blade mounting torque
Center bolt 40 Nm, max. 45 Nm.
Warning: Do not touch rotating blade.
