WARNING
POTENTIAL HAZARD
Using low flash point solvents or gaso-
line to clean the foam cover.
WHAT CAN HAPPEN
Low flash point solvents or gasoline can
catch fire or explode.
HOW TO AVOID THE HAZARD
Use parts cleaning solvent to clean the
foam cover.
7. Squeeze the excess water or solvent out
of the foam cover and let it dry.
CAUTION:
_
● Do not twist the foam cover when
squeezing it.
● Do not apply oil to the foam cover.
_
8. Inspect the foam cover. If damaged, re-
place it.
9. Install the foam cover onto the air filter el-
ement.
10. Install the air filter assembly and parts re-
moved for access.
NOTE:
_
The air filter element should be cleaned every
20 ~ 40 hours. It should be cleaned more of-
ten if the machine is operated in extremely
dusty areas. Each time filter element mainte-
nance is performed, check the air inlet to the
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.
_
CAUTION:
_
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, op-
eration without the filter element will affect
carburetor jetting with subsequent poor
performance and possible engine over-
heating.
