NOTE: Damaged, worn or loose air cleaner com-
ponents could allow unfiltered air into the engine
causing premature wear and failure. Replace all
damaged or worn components.
OPTIONAL OIL BATH AIR CLEANER
If the engine has an oil bath type air cleaner,
clean and service it after every 25 hours of opera-
tion or more frequently if conditions warrant. Refer
to Figure 5-3.
1 . Remove the cover, lift the element out of the
bowl and drain the oil from the bowl.
2. Thoroughly wash bowl and cover in clean sol-
vent. Swish the element in the solvent and al-
low it to dry.
NOTE: Do not use compressed air to dry the ele-
ment. The filtering material could be damaged.
3. Lightly re-oil the element with engine oil.
4. Inspect base and cover gaskets. Replace if
damaged.
OIL LEVEL
5. Install base gasket and place filter on air horn.
6. Add engine oil to filter and fill to the OIL LEVEL
mark.
7. Install filter element, cover gasket and cover.
Secure with wing nut finger tight only.
COOLING AIR INTAKE SYSTEM
Effective cooling of an air cooled engine depends
on an unobstructed flow of air over the cooling
fins. Air is drawn into the cooling shroud by fins
located on the flywheel. The blower housing, cool-
ing shroud, air screen covering the flywheel and
cooling fins on the cylinder and cylinder head must
be kept clean and unobstructed at all times.
Never operate the engine with the blower housing
or cooling shroud-removed. These devices direct
air flow over the cooling fins.
NOTE: Some engines use a plastic grass screen
and some use metal. The two are not interchange-
able unless other modifications are made to the
engine.
