SERVICE OF AIR CLEANER
A dirty air cleaner may block enough air's flowing into the
carburetor. To keep the carburetor in good working conditions,
please service the air cleaner periodically. If operating the engine
in extremely dusty area, the job should be done more often.
WARNING:
Never clean the air cleaner core in gasoline or low flash-point
detergents, or explosion may happen.
CAUTION:
Never run the engine without an air cleaner, or air with dirt and dust may enter the engine so speed
the engine's wear.
Dual element type
Unscrew the wing nut, dismantle the air cleaner housing.
Check if the two cores are damaged, if so, replace with new
one.
a) Foam filter element: clean with home detergents and
warm water (or non-flammable or high flash-point cleansing
solvents) and dry up, then soak in clean engine oil until
saturated. Squeeze out excess oil, otherwise, the engine
will discharge smoke in starting stage.
b) Paper filter element: knock the core against a solid plane
to get rid of accumulated dust or blow out dust from inside to
outside with high-pressure air flow (not more than 30psi).
Never clean with a brush, as brushing may force the dust
into the core fiber. If the core is extremely filthy, replace with
a new one.
