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 con ditions as indicated by the air re-
striction gauge. Ser vice the air cleaner as follows:
1. Release the top and bottom cover latches and
remove the air cleaner cover. Wash the cover
and dust ejection valve. Check that these com-
ponents are in good condition. The dust ejec-
tion valve is subject to wear and deterioration
and should be replaced
yearly
or when dam-
aged. The lips of the valve should close and fit
togeth er; 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 re
-
moved.
3. Replace 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 primary
ele-
ment carefully into the canister, applying pres-
sure at the outer rim of the filter; not at the flex
-
ible center. Make sure the filter element is
completely in place before installing the cover.
IMPORTANT:
DO NOT use
the
cover latches
to force the filter into the canister -- the cover
should fit on with
no extra force.
NOTE: DO NOT
use petroleum based lubri-
cants
on the sealing surfaces of the filter; use
tal cum powder or dry silicone lubricants if re-
quired for filter installation.
