Oil Change
1. Drain the used oil with the engine is warm. Warm oil drains quickly and completely.
2. Check that the fuel filler cap is tightened securely.
3. Place a suitable container below the engine to catch the used oil.
4. Remove the oil filler cap/dipstick and drain the oil into the container by tipping the engine toward the
oil filler neck.
Note
: Dispose of used motor oil in a manner that is compatible with the environment. It is
recommended to take used oil in a sealed container to your local recycling center or service
station for reclamation. Do not throw used oil in the trash, pour it on the ground or pour it
down the drain.
5. With the engine in a level position, fill the bottom edge of the oil fill hoke with the recommended oil.
6. Reinstall the oil filler cap/dipstick securely. If any oil is spilled, wipe it up immediately.
Note
: Running the engine with a low or excessive oil level can cause engine damage.
Air Cleaner
A dirty air cleaner will restrict air flow to the carburetor, reducing engine performance. If the engine is
operated in dusty areas, clean the air filter element more often than specified in the Maintenance
Schedule.
Inspection (Foam Air Filter Element)
1. Press the latch tab [1] on the top of the air
cleaner cover and remove the cover [2].
2. Inspect the air filter element [3].
3. Clean or replace the dirty air filter element.
Always replace a damaged air filter element.
Cleaning (Foam Air Filter Element)
1. Clean the filter element in warm soapy water, rinse, and allow to dry thoroughly. Or clean in a non-
flammable solvent and allow to dry.
2. Dip the element in clean engine oil, then squeeze out all the excess oil. The engine will smoke when
started if too much oil is left in the element.
3. Wipe dirt from the air cleaner body and cover, using a moist rag. Be careful to prevent dirt from
entering the carburetor.
4. Reinstall the filter element and air cleaner cover securely.
