AIR CLEANER
A dirty air cleaner will restrict air flow to the carburetor,
reducing engine performance. If you operate the engine
in very dusty areas, clean the air filter more often than
specified in the MAINTENANCE SCHEDULE
Operating the engine without an air filter, or with a
damaged air filter, will allow dirt to enter the engine,
causing rapid engine wear. This type of damage is not
covered by the
Distributor’s Limited Warranty
Inspection
Remove the air cleaner cover and inspect the filter
elements. Clean or replace dirty filter elements. Always
replace damaged filter elements. If equipped with an oil-
bath air cleaner, also check the oil level
Cleaning
Dual-Filter Element Types
1-
Remove the air cleaner cover nut from the air
cleaner cover, and remove the cover
2-
Remove the wing nut from the air filter, and
remove the filter
3-
Remove the foam filter from the paper filter
4-

CYCLONE DUAL-FILTER ELEMENT
5- Clean the air filter elements if they are to be
reused. Paper air filter element: Tap the filter
element several times on a hard surface to remove
dirt, or blow compressed air [not exceeding 207 kPa
(2.1 kgf/cm
2
, 30 psi)] through the filter element from
the inside. Never try to brush off dirt; brushing will
force dirt into the fibers
Foam air filter element: Clean in warm soapy water,
rinse, and allow to dry thoroughly. Or clean in non-
flammable solvent and allow to dry. Dip the filter
element in clean engine oil, then squeeze out all
excess oil. The engine will smoke when started if
too much oil is left in the foam
6- CYCLONE TYPE ONLY: Tap the air cleaner cover
several times on a hard surface to remove dirt, or blow
compressed air [not exceeding 207 kPa (2.1 kgf/cm
2
,
30 psi)] through the air cleaner cover from the outside
7- Wipe dirt from the inside of the air cleaner case
and cover using a moist rag. Be careful to
prevent dirt from entering the air duct that leads
to the carburetor
8- Place the foam air filter element over the paper
element, and reinstall the assembled air filter.
Be sure the gasket is in place beneath the air
filter. Tighten the wing nut securely
