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.
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. The oil should reach the top of the dipstick.
See Figure 24.
6. If the level is low, add a small amount of oil to the
oil fill hole and recheck. Repeat until the oil level
reaches the top of the dipstick. See Figure 24.
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. See Figure 24.

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. 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.
Allow ample time for complete drainage. See
Figure 25.
Full
Add 1.4-1.5 Oz.
(41-44 ml)
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 3.4 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: Measure the correct amount of oil and fill
the unit with approximately 3.4 ounces
(100 ml). Check the level with the dipstick. If
the level is low, add a small amount of oil
and recheck. Do not overfill.
6. Replace the oil fill plug/dipstick.
7. Reconnect the spark plug boot.
