10 CLEANING
CAUTION: Do not hose engine. Water can damage engine or contaminate
the fuel system.
Wipe deck with dry cloth.
Hose under deck by tilting the mower so that the spark plug is up.
10.1
Engine air cleaner
CAUTION: Do not allow dirt or dust to clog the air filter foam element.
The engine air cleaner element must be serviced (cleaned) after 25 hours normal mowing.
The foam element must be serviced regularly if the mower is used in dry dusty conditions.
10.1.1
To clean air filter (Fig. 10)
Press down the two tabs on top of the filter cover. Remove cover.
Wash filter element in soap water. DO NOT USE GASOLINE!
Air dry filter element.
Place a few drops of SAE30 oil on the foam filter and squeeze tightly to remove any
excess oil.
Reinstall filter.
NOTE: Replace filter if frayed, torn, damaged or unable to be cleaned.
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. 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. Install the blade adapter on
the crankshaft with the "star" away from the engine. Refer to figure 11. 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 (9.3)
