CHECKING THE OIL LEVEL
A WARNING: Wear gloves to prevent injury when
handling unit.
The importance of checking and
maintaining the proper oil level in the
crankcase cannot be
overemphasized. Check oil before
each use:
1.
Stop the engine and allow
oil to drain into the
crankcase.
2. Place the engine on a level
surface (Fig. 16).
3. Clean the area around the oil
plug before removing it. Keep
dirt, grass clippings, and other
debris out of the engine.
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. 17).
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. 17).
Repeat this procedure until the oil
level reaches the innermost thread
on the oil fill hole.
NOTE: Do not overfill the unit.
NOTE: Make sure the 0-ring is in place
on the oil fill plug when checking
and changing the oil (Fig. 18).
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. Remove the oil fill plug.
2. Pour the oil out of the oil fill hole and into a container by tipping
the unit to a vertical position (Fig. 19). 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. Refill the crankcase with 2.03
fluid ounce (60 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 fill line
on the label on the bottle
measures approximately
2.03 ounces (60 ml) (Fig.
20). 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. 17).
5. Replace the oil fill plug.
6. Reconnect the spark plug
boot.
