INLET AS 3900682 - Caterpillar

Never run the engine without an air cleaner element installed. Never run the 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.
Never service the air cleaner element with the engine running since this will allow dirt to enter the engine.
