Maintenance Instructions CLEANING
50
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 conditions as indicated by the air re-
striction gauge. Service the air cleaner as follows:
1. Lift Mono Latch Twist Lock™ and twist the
OptiAir™ cover to the left into the “open” posi-
tion 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 deteriora-
tion and should be replaced yearly or when
damaged. The lips of the valve should close
and t together; 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. Replace the lter 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 lter for damage or holes. The
safety lter 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
lter. Replace the lter 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 lter and OptiAir™
el ement carefully into the canister, applying
pres sure 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.
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.
