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. 20) 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. 21). 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. Pour 2.03 fl.oz. (60 ml) of SAE 30 oil into the oil fill hole. 

NOTE: DO NOT

overfill. Refer to 

Checking the Oil Level

.

NOTE:

Use the empty oil bottle saved from the initial use to

measure the correct amount of oil. Fill the oil bottle to the 2.03 fl.
oz (60 ml) fill line indicated on the back of the bottle (Fig. 22).

6. Wipe up any oil that may have spilled. 
7. Reinstall the oil fill plug.

NOTE:

Make sure the O-ring is in place on the oil fill plug (Fig. 20).
