Air Restriction Gauge Location
Inspect the paper element after every 100 hours of
service and replace the element and safety filter
yearly (or when dirty or damaged). More frequent
replacement may be required when operating in
extremely dusty conditions as indicated by the air
restriction gauge. Service the air cleaner as follows:
1.
Lift Mono Latch Twist Lock™ and twist the
OptiAir™ cover to the left into the "open"
position to remove the 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 replaced yearly 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.
Replace the filter element.
NOTE: Washing the element in water or clean-
ing solution is not recommended. Do not try to
clean the element with compressed air.
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.
Without removing, visually inspect the condition
of the safety filter for damage or holes. The
safety filter should only be removed for yearly
replacement (or when dirty or damaged).
6.
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.
7.
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.
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 OptiAir™ 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.
