elements. Clean them more frequently
in dusty operating conditions.

cleaner elements. Replace them
more frequently in dusty operating

7. Inspect the foam and paper elements, and replace
them if they are damaged or excessively dirty.
8. If the paper element is excessively dirty, replace it.
Note: Never try to brush dirt off the paper element;
brushing forces the dirt into the fibers.
9. Clean the foam element in warm, soapy water or in a
nonflammable solvent.
Note: Do not use gasoline to clean the foam
element because it could create a risk of fire or
explosion.
10. Rinse and dry the foam element thoroughly.
11. Dip the foam element in clean engine oil, then
squeeze out the excess oil.
Note: Excess oil in the foam element restricts the
air flow through the element and may reach the
paper filter and clog it.
12. Wipe dirt from the base and the cover with a moist
rag.
Note: Be careful to prevent dirt and debris from
entering the air duct leading to the carburetor.
13. Install the air cleaner elements and ensure that they
are properly positioned.
14. Securely install the cover with the 2 nuts.
