Service Precleaner and Air Cleaner Element
This engine is equipped with a replaceable, high
density paper air cleaner element. Some engines are
also equipped with an oiled, foam precleaner, located
in the outer air cleaner cover. See Figure 9.
Check the air cleaner daily or before starting the
engine. 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.
NOTE: Operating the engine with loose or damaged
air cleaner components could allow
unfiltered air into the engine causing
premature wear and failure.
Figure 9. Air Cleaner Assembly - Details.
Service Precleaner
If so equipped, wash and reoil the precleaner
every two months or every 25 hours of operation,
(more often under extremely dusty or dirty
conditions).
1. Loosen the air cleaner cover knobs and remove
the cover. See Figure 9.
2. Remove the precleaner.
3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until
all traces of detergent are eliminated. Squeeze out
excess water (do not wring). Allow the precleaner
to air dry.
4. Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
5. Reinstall the precleaner into the upper section of
the air cleaner cover. Make sure hole in precleaner
is aligned with the upper mounting knob.
6. Reinstall the air cleaner cover and secure with
the two knobs.
7. When precleaner replacement is necessary order
genuine Kohler Part No. 20 083 03-S.

3. 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
element. Replace a dirty, bent, or damaged
element with a genuine Kohler element. Handle
new elements carefully; do not use if the rubber
seal is damaged.
4. Clean all air cleaner components of any
accumulated dirt or foreign material. Prevent
any dirt from entering the throat of carburetor.
5. 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 11.

upper section of the air cleaner cover. Make sure
the hole in precleaner is aligned with the upper
mounting knob. See Figure 9.
