Air Cleaner Service

NOTICE: Operating the engine without an air cleaner, or with a damaged air cleaner, will
allow dirt to enter the engine, causing rapid engine wear.
Press down on the cover tabs and remove the cover.

Remove the filter from the air cleaner housing.

Inspect the filter, and replace it if damaged.

Clean the filter by tapping it several times on a

hard surface to remove dirt, or blow compressed
air through the air filter from the inside. Never
try to brush off dirt; brushing will force dirt into
the fibers.
Wipe dirt from the inside of the air cleaner housing and cover, using a moist rag. Be careful

to prevent dirt from entering the air duct that leads to the carburetor.
Reinstall the filter and cover.

Spark Plug Service
For good performance, the spark plug must be properly gapped and free of deposits.
Disconnect the spark plug cap and remove any dirt

from around the spark plug area.
Remove the spark plug with a spark plug wrench.

Inspect the spark plug. Replace it if the electrodes are worn, or if the insulator is cracked or

chipped.
