1. Release the two (2) air cleaner cover latches
and remove the foam precleaner by sliding it off
the paper element.
2. Wash the precleaner in warm water with deter
gent (replace the precleaner if worn or dam
aged). Rinse and allow to air dry (

wring dry).
3.
Lightly oil precleaner with new engine oil.
Squeeze foam to distribute oil and remove ex
cess oil.
4. Reinstall precleaner over paper element and re

photo). Make sure both latches are se
cure on the two (2) base receptacles.
IMPORTANT:
When latching the cover onto the
air cleaner base, make sure the cover is drawn
down tight on the base by
first engaging the
latch hooks into the receptacles
on the air
cleaner base, and then latching down tight.

Check/clean the air filter
after every 100 hours of
service
and replace the filter
every 400 hours.
Service the air filter as follows:
1. Remove air cleaner cover and precleaner as
noted above. Wash or blow off the interior of
the cover.

NOTE:
Use care when cleaning the filter ele
ment. The filter element and/or seal surface
may be damaged by tapping too hard or hitting
on an uneven surface or sharp edge. Washing
the paper element in water or cleaning solution
is
not recommended
. Do not try to clean the
filter element with compressed air. Do not oil the
paper element. Remember, replacing a filter is
less expensive than replacing a dusted engine.
4. Inspect the paper element by using a bright light
inside the filter to check for damage. Check the
element very carefully for
pin holes or other
damage
that will allow dirt to leak through the
paper media. Replace the filter if dirty or if
damage is noted.
5. Check the condition and resilience of the radial
sealing surface (inside of the open end) of the
filter. Replace the filter if any cracks, tears, or
other damage to the sealing surface are noted.
6. Carefully clean the air cleaner base and both the
outside and inside surfaces of the outlet tube
that the air filter slides onto.
IMPORTANT:
Any dust left on the inside of the
outlet tube will go into the engine and cause
premature wear.
7. Slide the precleaner over the paper filter and
reinstall on the air cleaner base. Make sure the
filter is seated tight and straight on the base
plate for proper sealing.
8. Reinstall the air cleaner cover [see cover instal
lation instructions, step (4), under precleaner
servicing instructions above].
