Air Filter Element Replacement

Maintenance Instructions

CLEANING

Inspect the paper element after every 100 hours of service and replace the element and safety filter yearly (or when dirty or damaged). More frequent replacement may be required when operating in ex- tremely dusty conditions. Service the air cleaner as follows:

1.Release the top and bottom cover latches and remove the air cleaner cover. Wash the cover and dust ejection valve. Check that these com ponents are in good condition. The dust ejec- tion valve is subject to wear and deterioration and should be replaced yearly or when dam- aged. 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 re- moved.

3.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.

NOTE: Washing the element in water or clean ing solution is not recommended. Do not try to clean the element with compressed air.

4.Without removing, visually inspect the condition of the safety filter for damage or holes. The safety filter should only be removed for yearly replacement (or when 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.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 safety filter and primary 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 talcum powder or dry silicone lubricants if re- quired for filter installation.

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.
