Engine Air Filter Service
The engine is equipped with a replaceable, high
density paper air cleaner element and an oiled, foam
precleaner, located in the outer air cleaner cover.
Check the air cleaner before each use. Check for a
buildup of dirt and debris around the air cleaner
system. Keep this area clean. Also check for loose or
damaged components. Replace all bent or damaged
air cleaner components.
WARNING: Operating the engine with
loose or damaged air cleaner compo-
nents could allow unfiltered air into the
engine causing premature wear and
failure.
Service the Air Filter Precleaner
Wash and reoil the precleaner every two months or
every 25 hours of operation, (more often under
extremely dusty or dirtyconditions).
• Loosen the air cleaner cover knobs and remove
the cover. Remove the precleaner from the cover.
Refer to Figure 25.
• Wash the precleaner in warm water with deter-
gent. Rinse the precleaner thoroughly until all
traces of detergent are eliminated. Squeeze out
excess water (do not wring). Allow the pre-
cleaner to air dry.
• Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
• Reinstall the precleaner into the upper section of
the air cleaner cover. Make sure hole in
precleaner is aligned with the upper mounting
knob.
• Reinstall the air cleaner cover and secure with
the two knobs.
Service the Air Filter Paper Element
Check the paper element every two months or every
25 hours of operation, (more often under extremely
dusty or dirty conditions). Clean or replace the ele-
ment as necessary. Replace the air cleaner element
annually, or every 100 hours.
• Remove the air cleaner cover. Service the pre-
cleaner if required.
• Remove the air cleaner element with the integral

• Gently tap the pleated side of the paper element
to dislodge dirt. Do not wash the paper element
or use pressurized air, as this will damage the

ment with a new element. Handle new elements
carefully; do not use if the rubber seal is
damaged.
• Clean all air cleaner components of any accumu-
lated dirt or foreign material. Prevent any dirt from
entering the throat of carburetor.
• Install the air cleaner element with the pleated
side "out" and seat the rubber seal onto the
edges of the air cleaner base. See Figure 26.
