Maintenance Instructions
CLEANING
68
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 element in water or cleaning solution is
not
recommended.
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
filter element if dirty or damaged.
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
safety filter should only be removed for
replacement
yearly
(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 pre-
mature engine wear.
7. After removing the safety filter, use a clean,
damp cloth and wipe the interior of the air clean-
er 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.

10. Install the cover with the word “TOP” properly
oriented to the top of the canister. Give the
cover a slight twist as it reaches the canister to
make sure the tab inside the cover goes into a
slot, otherwise the cover will not fit properly.
Make sure both the top and bottom cover
latches are securing the cover in place.

etc., and the hose clamps for tightness.
12. Reset the air filter restriction gauge (press but-
ton on the end of the indicator).
