CHANGING THE OIL
For a new engine, change the oil after the first 10 hours of
operation. Change the oil while the engine is still warm. The oil will
flow freely and carry away more impurities.
1. Unplug spark plug wire to prevent accidental starting.
2. Remove the oil fill plug/dipstick.
3. Pour the oil out of the oil fill hole and into a container by
tipping the unit to a vertical position (Fig. 17). Allow ample
time for complete drainage.

NOTE: Make sure the O-ring is in place on the oil fill plug/dipstick
when checking and changing the oil (Fig. 16).
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. 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. Pour fresh fuel into the bottle
and fill it to the top of the label. The top of the label on the
bottle measures approximately 3.04 ounces (90 ml).
Check the level with the dipstick. If the level is low, add a
small amount of oil and recheck. Do not overfill (Fig. 18).
6. Replace the oil fill plug/dipstick.
7. Reconnect the spark plug wire.
