2. Air cleaner service
A dirty air cleaner 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.
-N
ever use gasoline or low flash point solvents for cleaning the air
cleaner element. A fire or explosion could result.
CAUTION: Never run the engine without the air cleaner. Rapid engine wear
will result.
1. Remove the wing nut and the
air
cleaner cover. Remove the elements
and separate them. Carefully check
both elements for holes or tears and
replace if damaged.
2. Foam element: Clean in warm
soapy water, rinse and allow to dry
thoroughly. Or clean in high flash-
point solvent and allow to dry. Dip
the element in clean engine oil and
squeeze out all the excess. The
engine will smoke during initial
start-up if too much oil is left in the
foam.
3. Paper element: Tap the element
lightly several times on a hard
surface to remove excess dirt, or
blow compressed air through the
filter from the inside out. Never try
to brush the dirt off; brushing will
force dirt into the fibers.
