MAINTENANCE
CHANGING THE OIL
For a new engine, change the oil after the rst 10
hours of operation. Change the oil while the
engine is still warm but not hot. The oil will ow
freely and carry away more impurities.
1. Unplug spark plug boot to prevent accidental
starting.
2. Remove the oil ll plug / dipstick.
3. Pour the oil out of the oil ll hole and into a
container by tipping the unit to its side (Fig. 17).
Allow ample time for complete drainage.
NOTE: Wear gloves to prevent injury when
handling the unit.
4. 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.
5. Rell the crankcase with 1.7 uid oz. (50 mL) of
SAE 10W-40 SF, SG, or SH oil (Fig. 18).
NOTE: Carefully check the oil level with the
dipstick. If the level is low, add a small amount
of oil and recheck. Do not over ll (Fig. 15).
6. Replace the oil ll plug / dipstick.
7. Reconnect the spark plug boot.
