MAINTENANCE AND REPAIR INSTRUCTIONS
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 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 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 inner most thread (Fig. 18).
6. If the oil level is not touching the inner most thread on the
oil fill hole, add a small amount of oil to the oil fill hole and
recheck (Fig. 21). Repeat this procedure until the oil level
reaches the inner most thread on the oil fill hole.
NOTE: Do not overfill the unit.
NOTE: Make sure the O-ring is in place on the oil fill plug when
checking and changing the oil (Fig. 19).

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. 20). 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.
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. 21). 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. 21).
6. Replace the oil fill plug.
7. Reconnect the spark plug boot.
WARNING: Wear gloves to prevent injury when
handling unit.
