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. Check the condition and resilience of the radial
sealing surface (inside of the open end) of the fil-
ter. Replace the filter if any cracks, tears, or
other damage to the sealing surface are noted.
6. 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.
7. Check the outside surface of the outlet tube for
smoothness and cleanness (this is the sealing
surface).
8. Insert and seat the filter element carefully into
the canister, applying pressure 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.
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 required
for filter installation.
Air Filter Element Replacement
9. 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.
Proper Orientation of Air Cleaner Cover
10. Check the air intake hose for cuts, nicks, etc.,
