Clean and inspect the paper element after every 100 hours of service and replace the element yearly or after six (6) cleanings (or when dirty or damaged). More frequent cleaning may be required when operating in extremely dusty conditions as indicated by a loss of engine power. Service the air cleaner as follows:

1. Release the top and bottom cover latches and

remove the air cleaner cover. Wash the cover

and Vacuator™ valve. Check that these com-

ponents 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

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.

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.

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.

NOTE: Washing the element in water or clean-

ing solution is not recommended. Replace the

element if it does not clean up with compressed
