Maintenance Instructions
CLEANING
1. Release the top and bottom cover latches and
remove the air cleaner cover. Wash the cover
and Vacuator valve. Check that these components
are in good condition. The Vacuator
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.
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 lubricants
on the sealing surfaces of the filter; use talcum
powder or dry silicone lubricants if required
for filter installation.
Canister
3. Clean the filter element using low pressure
compressed air [less than 100 PSI (689 kPa)].
Blow out the filter from the interior of the element
while turning the element.

Filter Element
NOTE: Washing the element in water or cleaning
solution is not recommended. Replace the
element if it does not clean up 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. 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. 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.

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.
10. Check the air intake hose for cuts, nicks, etc.,
and the hose clamps for tightness.
11. Reset the air restriction indicator (press button
on top).
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).
