CHANGING THE OIL
Change the oil while the engine is still warm. The oil will flow freely
and carry away more impurities.
1. Clean the area around the oil fill plug (Fig. 17) to prevent debris
from entering the oil fill hole.
2. Unscrew the oil fill plug.
3. Tip the unit vertically to pour the oil out of the oil fill hole and into
a container (Fig. 19). Allow ample time for complete drainage.
NOTE: Dispose of the old oil according to federal, state and local
regulations.
4. Wipe up any oil that may have spilled.
5. Tilt the unit 30° to the side (Fig. 20).
6. Pour 3.04 fl.oz. (90 ml) of SAE 30 oil into the oil fill hole (Fig. 17).
WARNING:
DO NOT overfill the crankcase.
OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS
PERSONAL INJURY. Refer to Checking the Oil Level.
7. Wipe up any oil that may have spilled.
8. Make sure the O-ring is in place on the oil fill plug (Fig. 17).
9. Reinstall the oil fill plug.
MAINTAINING THE AIR FILTER
Failure to maintain the air filter can result in poor performance or
can cause permanent damage to the engine. Engine failure due to
improper air filter maintenance is not covered by the product warranty.
Cleaning the Air Filter
1. Remove the air filter cover: press in the lock tab and swing the
air filter cover up (Fig. 21).
2. Remove the air filter (Fig. 21).
3. Wash the air filter in detergent and water. Rinse the air filter
thoroughly and allow it to dry.
4. Lightly coat the air filter with clean SAE 30 oil.
5. Squeeze the air filter to spread and remove excess oil.
6. Reinstall the air filter (Fig. 21).
NOTE: Operating the unit without the air filter and air filter cover will
VOID the warranty.
7. Reinstall the air filter cover: place the slots on the air filter cover
onto the tabs on the backplate. Swing the air filter cover down
and press it closed until the lock tab snaps into place (Fig. 21).
