NOTE: Use care when cleaning the lter
element. The lter element and/or seal sur-
face may be damaged by tapping too hard or
hitting on an uneven surface or sharp edge.
Washing the paper element in water or clean-
ing solution is not recommended. Do not try
to clean the element with compressed air. Do
not oil the paper element. Remember, replac-
ing a lter is less expensive than replacing a
dusted engine.
4. Use a bright light inside the lter 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 lter element if dirty or damaged.
5. 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 not-
ed.
6. Without removing, visually inspect the condi-
tion of the safety lter for damage or holes.
The safety lter should only be removed for
yearly replacement (or when dirty or dam-
aged).
IMPORTANT: Prior to removing the safety
lter, 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 premature engine wear.
7. After removing the safety lter, 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 primary
lter element carefully into the canister, apply-
ing pressure at the outer rim of the lter; not at
the exible center. Make sure the lter ele-
ment is completely in place before installing
the cover.
IMPORTANT: DO NOT use the cover latch-
es to force the lter into the canister–the cover
should t on with no extra force.
NOTE: DO NOT use petroleum based lubri-
cants on the sealing surfaces of the lter; use
tal cum powder or dry silicone lubricants if
required for lter 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 t properly.
Make sure both the top and bottom cover
latches are securing the cover in place.

ness.

button on the end of the indicator).
