reading (Fig. 22).
3. Keep dirt, grass clippings and other debris out of the engine.
Clean the area around the dipstick before removing it.
4. Remove the oil fill plug.
5. Look into the oil fill hole, use a flashlight if needed. The oil
should be just touching the innermost thread (Fig. 23).
6. If the oil level is not touching the innermost thread on the oil fill
hole, add a small amount of oil to the oil fill hole and recheck
(Fig. 23). Repeat this procedure until the oil level reaches the
innermost thread on the oil fill hole.

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 boot to
prevent accidental starting.
2. Remove the oil fill plug.
3. Pour the oil out of the oil fill
hole and into a container by
tipping the unit to a vertical
position (Fig. 25). Allow ample
time for complete drainage.
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. Fig. 25
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. 26). 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. 26).
