AIR CLEANER
Check the air cleaner daily or before starting the
engine. Check for loose or damaged components and
check the condition of the filter element. Remove any
buildup of dirt and debris in the air cleaner housing.
NOTE
Operating the engine with loose or damaged air
cleaner components will allow unfiltered air into
the carburetor; causing extensive wear and
eventual failure of the engine.

Servicing the Precleaner
Wash and re-oil the foam precleaner at one month
intervals or after every 10 hours of operation (more
often under extremely dusty or dirty conditions),
whichever occurs first.
1. Unfasten the air cleaner cover retaining knob and
remove the air cleaner cover (Refer to Figure 23).
2. Remove the foam precleaner by sliding it up off the
paper element (Refer to Figure 23).
3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until all
traces of the detergent are eliminated. Squeeze
out (do not wring) excess water in a dry cloth.
Allow the precleaner to air dry.
4. Saturate the foam precleaner with new engine oil.
Squeeze out all excess oil.
5. Reinstall the foam precleaner over the paper
element.
6. Reinstall the air cleaner cover and secure with the
retaining knob.
Servicing the Paper Element
Every 100 hours of operation (more often under
extremely dusty or dirty conditions), replace the paper
element.
1. Unfasten the air cleaner cover retaining knob and
remove the air cleaner cover (Refer to Figure 23).
2. Remove the foam precleaner by sliding it up off the
paper element (Refer to Figure 23).
CAUTION
The air cleaner element cover plate (Refer to
Figure 23) must be properly installed to seal
against the gasket surface of the paper
element.
3. Remove the wing nut and element cover plate,
then lift out the paper air filter element.
4. Do not wash the paper element or use pressurized
air, as this will damage the element. Replace a
dirty, bent or damaged element. Handle new
elements carefully; do not use if the sealing
surfaces are bent or damaged.
5. When servicing the air cleaner, check the air
cleaner base. Make sure it is secured and not bent
or damaged. Also check the element cover for
damage or improper fit. Replace all damaged air
cleaner components.
6. Inspect the rubber grommet seal (Refer to Figure
23) for deterioration, cracks, and for a snug fit on
the carriage bolt. Replace if damaged or worn.
7. After making certain the carriage bolt is secured in
position by the retaining ring, slide the grommet
seal fully onto carriage bolt. Refer to Figure 23.
