Wash your hands with soap and water after handling used oil.
NOTE: Please dispose of used motor oil in a manner that is compatible with the environ-
ment. We suggest you take it in a sealed container to your local service for reclamation. Do

Air Cleaner Service
A dirty air cleaner will restrict air flow to the carburettor. To prevent carburettor malfunction, service the
air cleaner regularly. Service more frequently when operating the engine in extremely dusty areas.
WARNING: Never use gasoline or low flash point solvents for cleaning the air cleaner element. Afire or
explosion could result in.
CAUTION: Never run the engine without the air cleaner. Rapid engine wear will be the result.
- Remove the wing nut and the air cleaner cover. Remove the elements and separate them. Carefully
check both elements for holes or tears and replace if damaged.
- Foam element: clean in warm soapy water, risen and allow to dry thoroughly or clean in high flash-point
solvent and allow to dry. Dip the element in clean engine oil and squeeze out all the excess. The engine
will smoke during initial start –up if too much oil is left in the foam.
- Paper element: Tap the element lightly several times on a hard surface to remove excess dirt or blow
compressed air through the filter from the inside out. Never try to brush the dirt off. Brush will force dirt
into the fibbers.

- Visually inspect the spark plug. Discard it if the insulator is cracked or chipped.
- Measure the plug gap with a feeler gauge. The gap should be 0.7-0.8mm and correct as necessary by
bending the side electrode.

bly damage the engine. Never use a spark plug with an improper heat range.
