A dirty air cleaner will restrict air flow to the carburetor, reduc-
ing engine performance. If you operate the engine in very
dusty areas, clean the air filter more o?en than specified in the
maintenance schedule.
Opera ng the engine without an air filter, or with a damaged
air filter, will allow dirt to enter the engine, causing rapid en-
gine wear.
1. Remove the air cleaner cover
2. Inspect the filter elements and clean or replace dirty filter
elements. Always replace damaged filter elements. See

A dirty air cleaner will restrict air flow to the carburetor, reduc-
ing engine performance. If you operate the engine in very
dusty areas, clean the air filter more o?en than specified in the
maintenance schedule.
Opera ng the engine without an air filter, or with a damaged
air filter, will allow dirt to enter the engine, causing rapid en-
gine wear.
1. 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 le? in the foam.
2. Paper air filter element: Tap the filter element several
mes on a hard surface to remove dirt, or blow com-
pressed air (not exceeding 30 psi) through the filter ele-
ment from the inside. Never try to brush off dirt; brushing
will force dirt into the fibers.
3. 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.
4. 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 air filter wing
nut securely.
5. Install the air cleaner cover and ghten the wing nut se-
curely.
