Maintenance Instructions CLEANING
53
Inspect the paper element after every 100 hours of
service and replace the element and safety lter
yearly (or when dirty or damaged). More frequent
replacement may be required when operating in ex-
tremely dusty con ditions. Ser vice the air cleaner as
follows:
1. Release the top and bottom cover latches and
remove the air cleaner cover. Wash the cover
and dust ejection valve. Check that these com-
ponents are in good condition. The dust ejec-
tion valve is subject to wear and deterioration
and should be replaced yearly or when dam-
aged. The lips of the valve should close and t
togeth er; any cracks, deformation, or wear in
the valve is cause for replacement.
2. Remove the lter element by pulling it out of the
canister. There will be some initial resistance
as the lter seal breaks loose and slides off of
the outlet tube. Gently move the end of the
lter up and down and side to side or twist to
loosen the seal. Use gentle action to minimize
the amount of dust dislodged as the lter is re-
moved.
3. Use a bright light inside the element to inspect
for damage. Check the element very carefully
for pin holes or other damage that will allow
dirt to leak through the paper media. Replace
lter element if dirty or damaged.
NOTE: Washing the element in water or clean-
ing solution is not recommended. Do not try to
clean the element with compressed air.
4. Without removing, visually inspect the condition
of the safety lter for damage or holes. The
safety lter should only be removed for yearly
replacement (or when dirty or damaged).
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. Use a clean, damp cloth and wipe the interior of
the air cleaner canister clean. Use special care
to clean both the inside and outside surfaces
of the outlet tube.
IMPORTANT: Any dust left on the inside of the
outlet tube will go into the engine and cause
wear.
7. Check the outside surface of the outlet tube for
smoothness and cleanness (this is the sealing
surface).
8. Insert and seat the safety lter and primary lter
element carefully into the canister, applying
pressure at the outer rim of the lter; not at the
exible center. Make sure the lter element is
completely in place before installing the cover.
IMPORTANT: DO NOT use the cover latches
to force the lter into the canister -- the cover
should t on with no extra force.
NOTE: DO NOT use petroleum based lubri-
cants on the sealing surfaces of the lter; use
tal cum powder or dry silicone lubricants if re-
quired for lter installation.

9. Install the cover with the word “TOP” properly
oriented to the top of the canister. Give the
cover a slight twist as it reaches the canister to
make sure the tab inside the cover goes into a
slot, otherwise the cover will not t properly.
Make sure both the top and bottom cover
latches are securing the cover in place.
