2. Air Cleaner Maintenance

A dirty air cleaner may block proper airflow into the carburetor. Service the air cleaner

regularly to keep the engine running in peak condition. If operating the engine in an extremely

dusty area, the air cleaner should be serviced more often.

WARNING

Never clean the air cleaner in gasoline or low

flash-point detergents, explosion may occur.

CAUTION

Never run the engine without an air cleaner, or air with dirt

and dust may enter the engine and cause engine wear.

Unscrew the wing nut and dismantle the air cleaner housing. Check

the two cores for damage. If any, replace with new one.

a) Foam filter element: clean with mild detergent and warm water

(or non-flammable of high flash-point cleaning solvents) and

dry, then soak in clean engine oil until saturated. Squeeze out

excess oil before installing.

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 airflow (not more than 30 psi). Never clean

with a brush, as brushing may force the dust into the core fiber.

If the core is extremely filthy, replace it with a new one.
