3. Clean the cover thoroughly.
4. Remove the wing nut from the air filter, and remove
the filter (
Figure 29 ).
5. Remove the foam filter from the paper filter
(
Figure 29 ).
6. Inspect both air-filter elements, and replace them if
they are damaged.
Note:
Always replace the paper air-filter element at
the scheduled interval.
7. Clean the foam element as follows:
A. Wash the foam element in a solution of liquid
soap and warm water.
Note:
Squeeze the element to remove the dirt,
but do not twist it, because the foam may tear.
B. Dry it by wrapping it in a clean rag.
Note:
Squeeze the rag and foam element to dry
the element, but do not twist it, because the foam
may tear.
C. Saturate the element with clean engine oil.
Note:
Squeeze the element to remove excess oil
and to distribute the oil thoroughly. The foam
element should be damp with oil.
8. Clean the paper element by tapping the filter element
several times on a hard surface to remove the dirt.
Note:
Never brush dirt off the element or use
compressed air to remove dirt; brushing forces dirt
into the fibers and compressed air will damage the
paper filter.
9. Install the foam element, the paper element, and the
air-cleaner cover.
Important:
Do not operate the engine without
the air-cleaner elements, because extreme engine
wear and damage will likely result.
