the cap nuts, and remove the cover. Check the filter
to be sure it is clean and in good condition.

cleaning
1. Tap the filter several times on a hard surface to
remove dirt, or blow compressed air (not exceeding
0 psi [0kPa, .1kg/cm²]) through the filter from the
clean side that faces the engine. Never try to brush off
dirt. Brushing will force dirt into the fibers.

to remove dirt. Clean. If the outer filter is very dirty,
replace it.
. Wipe dirt from the air cleaner body and cover using a
moist rag. Be careful to prevent dirt from entering the
air duct that leads to the carburetor.
