Inspect the primary lter element after every 100
hours of service and replace the element and safe-
ty lter every 400 hours (or when dirty or damaged).
More frequent replacement may be required when
operating in extremely dusty conditions as indicated
by the air lter restriction gauge. Service the air
cleaner as follows:
1. Unlatch and remove Enginaire™ air cleaner
cover. Wash the cover. Check that the cover is
in good condition.
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 o 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. Discard the lter element if excessive air ow
restriction has been indicated by the air lter
restriction gauge and proceed to Step 6. Clean
the lter element by gently tapping on a at,
hard surface. If excessive restriction still exists
after cleaning the element, it should be re-
placed.
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
element with compressed air. Do not oil the
paper element. Remember, replacing a lter is
less expensive than replacing a dusted engine.
4. Use a bright light inside the lter element to in-
spect 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.
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. Without removing, visually inspect the condition
of the safety lter for damage or holes. The
safety lter should only be removed for replace-
ment every 400 hours (or when dirty or dam-
aged).
IMPORTANT: Prior to removing the safety lter,
make sure the inside surface of the air cleaner
canister is clean. This will minimize the risk of
dirt entering the outlet tube which can cause pre-
mature engine wear.
