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/dipstick.
3. Pour the oil out of the oil fill hole and into a container by
tipping the unit to a vertical position (Fig. 26). Allow ample
time for complete drainage.

6. Replace the oil fill plug/dipstick.
7. Reconnect the spark plug boot.
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. The top of the label
on the bottle measures approximately 3.4 ounces (100
ml) (Fig. 27). Check the level with the dipstick. If the
level is low, add a small amount of oil and recheck. Do
not overfill (Fig. 27).

CAUTION:
Wear gloves to prevent injury when
handling the unit.
CHECKING THE OIL LEVEL
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 unit on a flat, level surface to get a proper oil
level reading.
3. Keep dirt, grass clippings and other debris out of the
engine. Clean the area around the oil fill plug/dipstick
before removing it.
4. Remove the oil fill plug/dipstick and wipe off oil. Reinsert it
all the way back in.
5. Remove the oil fill plug/dipstick and check the oil level. Oil
should be up to the top of the dipstick (Fig. 24).
6. If the level is low, add a small amount of oil to the oil fill
hole and recheck (Fig. 25). Repeat this procedure until the
oil level reaches the top of the dipstick.
NOTE: Do not overfill the unit.
NOTE:
Make sure the O-ring is in place on the oil fill plug/dipstick
when checking and changing the oil (Fig. 25).
