Air Cleaner Element and Inner Element Service This engine is equipped with a heavy-duty high density paper air cleaner element surrounding a canister style inner element. Cleaning is not recommended, each element should be replaced when dirty. The air cleaner system should be inspected daily or before starting the engine, for a buildup of dirt and debris, or for any damaged or loose components. Do not operate the engine without the complete air cleaner system installed and properly secured. After the main element is removed, check the condition of the inner element. It should be replaced whenever it appears dirty, typically every other time the main element is replaced. Clean the area around the base of the inner element before removing it, so dirt does not get into the engine. See Figure 17. Air Intake System and Air Cleaner Components Air Cleaner Housing/End Cap Assembly Make sure air cleaner housing including the dust ejector valve and the end cap is in good condition and not cracked.
