CHECKING THE OIL LEVEL
--
i
_ ARNING: To avoid serious personal injury, always turn the
unit off and allow it to cool before cleaning or maintaining it.
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 in a horizontal
position to get a proper oil
level reading (Fig. 13).
3. Keep dirt, grass clippings
and other debris out of the
engine. Clean the area
around the dipstick 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. 14).

6. If the oil level is not touching
the inner most thread on the Oil Fill Plug
oil fill hole, add a small
amount of oil to the oil fill hole
and recheck (Fig. 17). Repeat
this procedure until the oil
level reaches the inner most O-Ring
thread on the oil fill hole.
NOTE: Do not overfill the unit.

plug when checking and
changing the oil (Fig. 15). Fig. 15
CHANGING THE OIL
--
i
_ CAUTION"
Wear gloves to prevent injury when handling the unit.
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. Remove the oil fill plug.
2. Pour the oil out of the oil fill
hole and into a container by
tipping the unit to a vertical
position (Fig. 16). Allow
ample time for complete
drainage.
3. 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.
4. Refill the crankcase with
3.04 fl.oz. (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
fi.oz. (90 ml) (Fig. 18).
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. 14).
5. Replace the oil fill plug.
6. Reconnect the spark plug boot.
AIR FILTER MAINTENANCE
_L_ ARNING:
To avoid serious personal injury, always turn the
unit off and allow it to cool before cleaning or maintaining it.
Cleaning the Air Filter
