Precleaner
Clean or replace the air cleaner precleaner after ev-
ery 25 hours of service; more often in extremely
dusty or dirty conditions. Service the precleaner as
follows:
1. Release the two (2) air cleaner cover latches
and remove the foam precleaner by sliding it o
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 (DO NOT
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-
install the cover with the proper orientation (re-
fer to Proper Orientation of Air Cleaner
Cover 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 rst engaging the
latch hooks into the receptacles on the air
cleaner base, and then latching down tight.
Paper Air Filter
Check/clean the air lter after every 100 hours of
service and replace the lter every 400 hours.
Service the air lter as follows:
1. Remove air cleaner cover and precleaner as
noted above. Wash or blow o the interior of
the cover.
2. Carefully slide paper lter o of the outlet tube
on the base, making sure that dust does not fall
down into the opening.
3. Clean the lter by gently tapping on a at,
hard surface.

NOTE: Use care when cleaning the lter ele-
ment. The lter 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
lter element with compressed air. Do not oil the
paper element. Remember, replacing a lter is
less expensive than replacing a dusted engine.
4. Inspect the paper element by using a bright light
inside the lter 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 lter 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
lter. Replace the lter 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 lter 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 lter and
reinstall on the air cleaner base. Make sure the
lter 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].
