Note: Be careful to prevent dirt and debris from
falling into the base.

6. Remove the foam element from the paper element
(Figure 43).
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 fuel 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.
