4. Remove the air filter element, and separate
it from the frame.
5. Wash the air filter element gently but thor-
oughly in solvent.
w
Always use parts cleaning solvent to clean
the air filter element. Never use low flash
point solvents or gasoline to clean the air fil-
ter element because the engine could catch
fire or explode.
6. Squeeze the excess solvent out of the air fil-
ter element and let it dry.
cC
Do not twist the air filter element when
squeezing it.

ping.

NOTE:
The air filter element should be cleaned every
20–40 hours. It should be cleaned and lubricat-
ed more often if the machine is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions. Check
the air filter case rubber joint to the carburetor
and manifold fittings for an airtight seal. Tighten
all fittings securely to avoid the possibility of
unfiltered air entering the engine.
cC
Never operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally, opera-
tion without the air filter element will affect
carburetor jetting with subsequent poor per-
formance and possible engine overheating.
