MAINTENANCE
6. Oil the foam element by dipping it in clean engine oil and
squeezing out all excess oil. If too much oil is left in the foam, the
engine may smoke when started.
7. Clean the paper element by tapping it on a hard surface to knock
off dirt or by blowing compressed air not exceeding 30 psi (207
kPa) through the element from the inside. Never try to brush off
the dirt, as that just forces it into the paper filter fibers.
8. Use a damp rag to wipe any dirt from the inside of the air cleaner
housing and cover. Be careful not to allow dirt into the duct
leading to the carburetor. Be sure the rubber seal in the base is in
place and in good condition.
9.
Place the foam element over the paper element, and install the
filter in the air cleaner housing.
10. Reinstall the air cleaner housing cover and wing nut.
