Air Filter Maintenance
A dirty air filter may restrict air from entering the engine.
To prevent engine failure, the air filter should be
maintained regularly. If the engine is operated in a dusty
place, it needs to be maintained more frequently.
Never use fuel or a solvent with a low ignition point
to clean the air filter element, doing so may cause
explosion. Please clean the element with warm
soapy water or non-flammable solvents.
CAUTION
Never run the engine without the air filter and cover
installed or damage to the engine could result. Damage
to the engine by not having the air filter and cover
installed is not covered under warranty.
1) Remove the air filter cover and air filter element
assembly.
2) Carefully separate the foam filter element from the
Paper filter element assembly.
a. Paper filter element: Remove the dust by
tapping the filter element several times on a
hard surface or use compressed air from inside
out.
b. Foam filter element: Wash it with warm, soapy
water, then dry it. Soak it in the clean engine oil
and squeeze out the excess oil. If too much oil
remains in the foam filter element, there will be
smoke coming out from the engine in the initial
startup stage.
3) Clean off dust on the air filter cover and inner
surface with a wet rag. Be careful not to allow
dust to enter the engine.
4) Install the filter element assembly and the air
filter cover.
