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.
Never use gasoline or low flash point solvents for cleaning the air
cleaner element. A fire or explosion could result.
Never run the engine without the air cleaner. Rapid engine wear
will result.
Dual element type
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: Wash the element in
a solution of household detergent
and warm water, then rinse thor-
oughly, or wash in nonflammable or
high flash point solvent. Allow the el-
ement to dry thoroughly.
Soak the element in clean engine oil
and squeeze out the excess oil. 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 sur-
face 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. Replace the pa-
per element if it is excessively dirty.
