Air Restriction Gauge Location
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 extremely dusty conditions as indicated by the air restriction gauge. Service the air cleaner as follows:
1.Lift Mono Latch Twist Lock™ and twist the OptiAir™ cover to the left into the "open" position to remove the air cleaner cover. Wash the cover and dust ejection valve. Check that these components are in good condition. The dust ejection 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.
3.Replace the filter element.
NOTE: Washing the element in water or clean- ing solution is not recommended. Do not try to clean the element 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.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).
6.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.
7.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 filter and OptiAir™ el- ement carefully into the canister, applying pres- sure 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.
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.
