Service Interval:
Inspect the air cleaner elements after each use.
Clean the cover, base, foam and paper elements after every 25
operating hours.
Replace the elements after ever 250 operating hours (sooner if they
are damaged or excessively dirty)
NOTE
: Do not operate the engine without the air cleaner assembly; extreme engine
damage will occur.

2. Disconnect the wire from the spark plug (Fig. 5 & 7)

6. Remove the foam element from the paper element.
7. Inspect the foam and paper elements, and replace them if they are damaged or

8. Tap the paper element on a hard surface several times or use compressed air not
exceeding 30 psi (207 kPa) through the filter from the wire screen side to remove
any excess dirt. 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.

nonflammable
solvent.
10. Rinse and dry the foam element thoroughly.
11. Dip the foam element in clean engine oil, then squeeze out the excess oil.

Excess oil in the foam element restricts the air flow through the element and
