CHANGING THE OIL
WARNING:
To avoid serious personal injury, always turn the
unit off and allow it to cool before you clean or service it.
WARNING:
Wear gloves to prevent injury when handling unit.
Change the oil per the Maintenance
Schedule. Change the oil while the
engine is still warm. The oil will flow
freely and carry away more impurities.
1. Remove the oil fill plug.
2. Pour the oil out of the oil fill hole
and into a container by tipping
the unit to the side (Fig. 21).
Allow ample time for complete
drainage.
3. Wipe up any oil residue on the
unit and clean up any oil that
may have spilled. Dispose of
the oil according to Federal,
State and local regulations.
4. Tilt the unit 30° to the side (Fig. 22).
5. Refill the crankcase with 3.04 fluid ounce (90 ml) of SAE 30 SF, SG, SH oil.
NOTE: Use the bottle and spout saved from initial use to measure the
correct amount of oil. The top of the label on the bottle measures
approximately 3.04 ounces (90 ml) (Fig. 22). Check the level. See
Checking the Oil Level. If the level is low, add a small amount of oil
and recheck. Do not overfill (Fig. 22).
6. Replace the oil fill plug.
