Engine Air Cleaner Primary Element - Clean / Replace
NOTICE: Never run engine without an air cleaner element installed. Never run engine with a damaged
air cleaner element. DO NOT use air cleaner elements with damaged pleats, gaskets or seals. Dirt
entering the engine causes premature wear and damage to engine components. Air cleaner elements help
to prevent airborne debris from entering the air inlet.
NOTICE: Never service the air cleaner element with the engine running since this will allow dirt to enter
the engine.
If the air cleaner element becomes plugged, the air can split the material of the air cleaner element.
Unfiltered air will drastically accelerate internal engine wear.
• Check precleaner and the dust bowl daily for accumulation of dirt and debris. Remove any dust
and debris, as needed.
• Operating in dirty conditions may require more frequent service of the air cleaner element.
• The air cleaner element should be replaced at least one time per year. This replacement should
be performed regardless of the number of cleanings.
Replace the dirty air cleaner elements with clean air cleaner elements. Before installation, the air
cleaner elements should be throughly checked for tears and/or holes in the filter material. Inspect the
gasket or the seal of the air cleaner element for damage.
NOTICE: The primary air cleaner element can be used up to six times if the element is properly cleaned
and properly inspected. Replace the primary element at least once a year, regardless of number of
cleanings.
An indicator
(1) mounted on the air cleaner cover will
turn red when the outer air filter element requires
cleaning.
