Air Filter Restriction Gauge Location
Inspect the paper element after every 100 hours of
service and replace the element and safety filter ev-
ery 400 hours (or when dirty or damaged). More
frequent replacement may be required when operat-
ing in extremely dusty conditions as indicated by the
air filter restriction gauge. Service the air cleaner as
follows:
1.
Unlatch and remove Enginaire™ air cleaner
cover. Wash the cover and dust ejection valve.
Check that these components are in good
condition. The dust ejection valve is subject to
wear and deterioration and should be inspected
carefully and replaced every 2 years or when
damaged. The lips of the valve should close and
fit together; any cracks, deformation, or wear in
the valve is cause for replacement.
2.
Remove the filter element by pulling it out of the
canister. There will be some initial resistance as
the filter seal breaks loose and slides off of the
outlet tube. Gently move the end of the filter 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 filter is removed.
3.
Discard the filter element if excessive air flow
restriction has been indicated by the air filter re-
striction gauge and proceed to Step 6. Clean the
filter element by gently tapping on a flat, hard
surface. If excessive restriction still exists after
cleaning the element, it should be replaced.

Air Filter
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 ele-
ment in water or cleaning solution is not recom-
mended. Do not try to clean the element with
compressed air. Remember replacing a filter is
less expensive than replacing a dusted engine.
4.
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 element
if necessary.
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.
Without removing, visually inspect the condition
of the safety filter for damage or holes. The safe-
ty filter should only be removed for replacement
every 400 hours (or when dirty or damaged).
IMPORTANT: Prior to removing the safety filter,
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 prema-
ture engine wear.
7.
After removing the safety filter, use a clean, damp
cloth and wipe the interior of the air cleaner can-
ister 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.
8.
Check the outside surface of the outlet tube for
smoothness and cleanness (this is the sealing
surface).
9.
Insert and seat the safety filter and primary filter
el ement carefully into the canister, applying
pres sure at the outer rim of the filter; not at the
flexible center. Make sure the filter element is
completely in place before installing the cover.
NOTE: DO NOT use petroleum based lubri cants
on the sealing surfaces of the filter; use tal cum
powder or dry silicone lubricants if required for
filter installation.
