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 ex-
tremely dusty conditions as indicated by the air restric-
tion 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.
