   Remove the foam precleaner (D) from the paper filter element (E). If the foam precleaner is dirty:
   • Wash precleaner in a solution of warm water and liquid detergent. Do not put engine oil on precleaner. Engine oil may wick into the paper filter element and result in poor engine performance.
     
   • Rinse precleaner thoroughly. Squeeze out excess water in a dry cloth until precleaner is completely dry.
   • Replace the precleaner if damaged or missing.

     Dirt and debris can enter the engine through a damaged filter element:

     • Do not wash paper element.

     • Do not attempt to clean paper element by tapping against another object.

     • Do not use pressurized air to clean element.

     • Replace element only if it is very dirty or damaged or if the seal is cracked.
