AIR FILTER SERVICE
A dirty air filter will restrict air flow to the carburetor. To prevent
carburetor malfunction, service the air cleaner regularly. Service more
frequently when operating the engine in extremely dusty areas.
1 NOTICE )
Never run the engine without the air filter. Rapid engine wear will
result.
1. Remove the cover wing nut, then remove the air cleaner cover.
2. Remove the filter wing nut, then remove and separate the air filter
elements. Carefully check both elements for holes or tears, and
replace the filter if damaged.
3. Foam element: Clean in warm soapy water, rinse and allow to dry
thoroughly. Or clean in nonflammable solvent and allow to dry. Dip
the element in clean engine oil and squeeze out all excess oil. The
engine will smoke during initial running if too much oil is left in the
foam.
Using gasoline or flammable solvent to clean the filter element can
lead to a fire or explosion. Use only soapy water or nonflammable
solvent.
4. Paper element: Tap the element several times on a hard surface to
remove excess dirt, or blow compressed air [not exceeding 30 psi
(207 kPa, 2.1 kg/cm’)] through the filter from the inside. Never try to
brush the dirt off; brushing will force dirt into the fibers.
5. Wipe dirt from the inside of the air cleaner housing and cover, using
a moist rag. Be careful to avoid dropping dirt into the air cleaner
duct that leads to the carburetor.
6. Reinstall the air filter and cover.
