MAINTENANCE
Kohler Engine Air Filter
If the engine seems to lack power or runs
rough the reason may be that the air filter is
clogged.
It is therefore important to service the air filter
at regular intervals (see “Maintenance
Schedule” on page 35 for correct service
interval).
1. Fold open the engine cover.
2. Unscrew the wing nut (A) on top of the
air filter and remove the cover.
3. Carefully remove the precleaner. Wash
and re-oil the precleaner. Wash the
precleaner in warm water with detergent.
Rinse precleaner with clear warm water.
Squeeze water out (do not wring to avoid
tearing). Allow to dry before lightly oiling
with fresh engine oil and installing it over
the paper filter.
4. Replace the paper filter if it is clogged
with dirt. Unscrew the wing nut (B) and
remove the paper filter.
5. The paper filter may be carefully tapped
on a hard surface to remove dust. Do not
try to wash or blow it with compressed
air.
6. Insert the paper filter and check that it is
correct sealed to its seat. Tighten the
paper filter wing nut and install the
precleaner over the paper filter.
7. Fit the air filter cover and tighten its wing
nut.
