your unit off and allow it to cool before you clean or service 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 on a flat,
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.
Check the oil level. Oil
should be just to the
bottom of the threads of
the oil fill hole. (Fig. 19).
6.
If the level is low, add a
small amount of oil to the
oil fill hole and recheck
(Fig. 19). Repeat this
procedure until the oil
level reaches the the
bottom of the threads in
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. 18).

AUTION:
Wear gloves to prevent injury when handling
the unit.
For a new engine, change the oil after the first 25 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 the side
(Fig. 20). 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 fluid ounce (90 ml) of SAE 30 SE
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 (Fig. 19). If the level is low, add a small amount of oil
and recheck. Do not overfill.
5.
Replace the oil fill plug.
AIR FILTER MAINTENANCE
I_IL
AUTION:
Wear gloves to prevent injury when handling
the unit.
Cleaning the Air Filter
Clean the air filter every 10 hours of operation. It is an important item
to maintain. Failure to maintain your air filter properly can result in poor
performance or can cause permanent damage to your engine.
Air Filter Cover
1.
Open the air filter cover by
._ri/,_
unscrewing the air filter
screw (Fig. 22).
2.
Remove the air filter (Fig. 25).
3.
Wash the filter in detergent
"*Screwr
and water (Fig. 24). Rinse
the filter thoroughly and
allow it to dry.
4.
Replace the air filter into
the base plate (Fig. 25).
NOTE:
If the unit is operated
without the air filter,
you will VOID the
warranty.
5.
Reinstall the air filter
cover. Position the hooks
on the air filter cover to
the top of the back plate
and lower the air filter
cover down so that the air
filter screw aligns with the
screw hole on the back
plate (Fig. 23).
6.
Turn the air filter screw
clockwise until the air filter
screw is tight (Fig. 22).
NOTE:
Do not over tighten as
this may strip the
screw.
IDLE SPEED ADJUSTMENT
The idle speed of the engine is
adjustable. An idle adjustment
screw is between the air filter
cover and the engine starter
housing (Fig. 26).
NOTE:
Careless adjustments
can seriously damage
your unit. Aside from

should make carburetor adjustments.
First, Check Fuel
Idle Adjustment Screw
Old fuel is usually the reason
for idle speed problems. Drain
and refill the tank with fresh
fuel prior to making any
adjustments.
Refer to Oil and
Fuel Information.
Second, Clean Air Filter
The condition of the air filter is

important to the operation of
the unit. A dirty air filter will restrict air flow. This is often mistaken
for an out of adjustment idle. Check the condition of the air filter
before adjusting the idle speed screw. Refer to Air Filter
Maintenance.
Third, Adjust Idle Speed Screw
_i_1
ARNING:
The cutting attachment
may spin during idle I
speed adjustments.
Wear protective clothing and observe
a safety nstruct ons to prevent serous persona
n ury.
If, after checking the fuel and cleaning the air filter, the engine still
will not idle, adjust the idle speed screw as follows:
1.
Start the engine and let it run at a high idle for a minute to warm
up. Refer to Starting/Stopping
Instructions.
2.
Release the throttle trigger and let the engine idle. If the engine
stops, insert a small phillips or flat blade screwdriver into the
hole in the air filter/muffler
cover (Fig. 26). Turn the idle speed
screw in, cloclcwise,
1/8 of a turn at a time (as needed) until the
engine idles smoothly.
NOTE:
The cutting attachment
should not rotate when the engine
idles.
