Never clean the air cleaner filter with gasoline or low flash-point detergents, or explosion may happen.

2. MAINTENANCE METHOD

1) Replacement of engine oil (see “Oil Level Check” in Chapter IV to check oil level)

The oil will drain more rapidly and completely when the engine is warm.

(1) Remove the oil filler cap and drain plug to drain engine oil thoroughly.

(2) Reinstall the drain plug and screw in securely.

(3) Fill with the specified engine oil up to the upper level mark.

(3) Reinstall the oil filler cap.

2) Maintenance of air filter

A dirty air filter can restrict air flowing into the carburetor. To keep the carburetor in good working condition, please service

the air filter periodically (clean air filter element after 20h of use). If the engine is being operated in an extremely dusty area,

clean the filter more often.

(1) Remove the wing nut from the filter cover and remove the cover.

(2) Remove the wing nut from air filter and pull the air filter with pre-cleaner from

the threaded stud.

(3) Pull the pre-cleaner off the paper filter assembly and shake the dirt from the

foam pre cleaner and from the paper filter.

Note: If the foam Pre-cleaner or paper filter is too dirty to clean (clogged) or

damaged you must replace the filter with a new filter.

(4) Clean the air filter cover and inner surface with wet cloth, be careful not to allow

the dust to enter into the carburetor.

(5) Reinstall the air filter with pre-cleaner and secure with the wing nut.

(6) Reinstall the filter cover and secure with the wing nut.

Do not dump oil containers or discarded engine oil into rubbish boxes or onto the ground. For the sake of environmental

protection, we suggest you take in discarded engine oil with a closed container and bring to local recycling station.
