CHECKING THE OIL LEVEL
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.
The importance of checking and maintaining the proper
oil level in the crankcase cannot be overemphasized.
Check oil before each use:
1. Stop engine and allow oil to drain into the crankcase.
2. To get a proper oil level reading, place the unit on a
flat, level surface with the cultivator in a horizontal
position (Fig. 17).
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 oil level.
Oil should be up to the top of the dipstick (Fig. 18).
6. If the level is low, add a small amount of oil to the oil
fill hole and recheck (Fig. 18). Repeat 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. 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.
CAUTION: Wear gloves to prevent injury
when handling the unit.
1. Unplug spark plug boot to eliminate starting.
2. Fold the handlebars down to ease unit maneuvering.
3. Remove the oil fill plug/dipstick.
4. 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.

5. 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.
6. Refill the crankcase with 3.4 fluid ounce (100 ml) of
SAE 30 SF, SG, SH oil.
NOTE: For cold weather operation, where
temperatures
plummet below 40°F (4°C), use a high-quality
SAE 10W30 weight oil of API (American
Petroleum Institute) service class SF, SG, SH.
NOTE: Use the bottle and spout saved from initial use to
measure the correct amount. 3.4 ounce (100 ml)
is approximately to the top of the label on the
bottle (Fig. 21). Check the level with the dipstick.
If the level is low, add a small amount of oil and
recheck (Fig. 18). Do not overfill.
7. Replace the oil fill plug/dipstick.
8. Reconnect spark plug boot. Reposition the
handlebars to the operating position.
