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 (Fig. 2).
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. 19).
6. If the level is low, add a small amount of oil to the oil fill
hole and recheck (Fig. 20). 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. 20).
CHANGING THE OIL
CAUTION: To prevent extensive engine wear and
damage to the unit, always maintain the proper oil level in
the crankcase. Never operate the unit with the oil level
below the bottom of the dipstick.

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. 21). 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.
22). Check the level with
the dipstick. If the level is
low, add a small amount of
oil and recheck. Do not
overfill (Fig. 22).
6. Replace the oil fill
plug/dipstick.
7. Reconnect the spark plug
boot.
