Clean Pre-Cleaner and Air Cleaner Cartridge

Your engine is equipped with an oval dual element air cleaner: the two elements include a foam pre-cleaner and an air cleaner cartridge.

To remove the air cleaner element, loosen two cover screws and lift cover. Carefully remove foam pre-cleaner and air cleaner cartridge.

To clean pre-cleaner and air cleaner cartridge, wash in liquid detergent and water. Allow to dry thoroughly before using. Do not oil the pre-cleaner or cartridge. Replace if very dirty or damaged.

After cleaning the pre-cleaner and air cleaner cartridge, replace pre-cleaner on air cleaner cartridge.

Install air cleaner assembly (pre-cleaner and cartridge) in base. Then install cover on air cleaner and tighten screws securely to base.

BASE

Stop engine. Wait 30 seconds and recheck oil level. If required, add oil to bring level to FULL mark on dipstick.

NOTE: Do not use petroleum solvents, e.g., kerosene, which will cause the cartridge to deteriorate. Do not use pressurized air to clean cartridge. Pressurized air can damage the cartridge.

Clean and Replace Spark Plug

Change the spark plug every 100 hours of operation or once each year, whichever comes first. This will help your engine to start easier and run better.

Check Engine — Finger Guard/Muffler

Do not clean engine with a forceful spray of water because water could contaminate fuel system. With a brush or cloth, clean any debris from finger guard after every use to prevent engine damage caused by overheating.

CLEAN

Before running engine, clean muffler area to re- move all grass and combustible debris.
