AIR CLEANER: Your air cleaner may
have only the paper cartridge, or it may
have the cartridge and a foam pre-clean-
er. If it has the pre-cleaner, service the
cartridge every 100 hours and the pre-
cleaner every 25 hours or once a year, whichever
comes first. If the air cleaner doesn't have the pre-
cleaner, service the cartridge every 25 hours or once a
year, whichever comes first. Under dusty conditions,
service more often.
CAUTION
Do not use petroleum solvents such as kerosene to
clean the cartridge. They may cause deterioration of
the cartridge. DO NOT OIL THE CARTRIDGE OR USE
PRESSURIZED AIR TO CLEAN OR DRY THE CAR-
TRIDGE.
Remove the wing nut and cover. Carefully remove the
foam pre-cleaner, if equipped, from the cartridge.
To service the pre-cleaner:
1. Wash in liquid detergent and water.
2. Squeeze dry in a clean cloth.
3. Saturate in clean engine oil.
4. Squeeze in a clean, absorbent cloth to remove all
excess oil.
To service the cartridge:
1. Tap gently on a clean surface.
2. Replace if very dirty or wash in a non-sudsing
detergent and warm water solution.
3. Rinse thoroughly from the mesh side with flowing
water until the water is clear.
4. Allow to stand and air dry before reinstalling.
Carefully place the pre-cleaner back over the cartridge
and reinstall the air cleaner cover and wingnut.
CLEAN ENGINE: Remove dirt and debris with a cloth
or a brush. Do not clean with a forceful spray of water.
Water might contaminate the fuel system.
CAUTION
Periodically clean the muffler area to remove com-
bustible debris.
