2. Remove the air filter case cover by
unhooking the fasteners.
3. Remove the air filter element by unhooking
the fastener.
4. 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.
5. Squeeze the excess solvent out of the air
filter element and let it dry.
cC
Do not twist the air filter element when
squeezing it.
6. Inspect the air filter element. If damaged,
replace it.
7. Apply foam air filter oil to the air filter ele-
ment.

NOTE:
The air filter element should be wet but not drip-
ping.
8. Install the air filter element.
9. Install the air filter case cover by hooking
the fasteners onto the air filter case.
10. Install the front cover by installing the bolts.
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 of the air filter case for obstructions. Check
the air cleaner rubber joint to the carburetor and
manifold fittings for an airtight seal. Tighten all
fittings securely to avoid the possibility of unfil-
tered air entering the engine.

cC
Never operate the engine with the air filter
element removed. This will allow unfiltered
air to enter the engine, causing rapid engine
wear and possible engine damage.
Additionally, operation without the filter ele-
ment will affect carburetor jetting with sub-
sequent poor performance and possible
engine overheating.
