SAFETY WARNINGS FOR GAS UNITS
its vapors can explode if ignited. Take the following
WARNING: Gasoline is highly flammable and
precautions:
Store fuel only in containers specifically designed and approved
for the storage of such materials.
Always stop the engine and allow it to cool before filling the
tank. Never remove the fuel tank cap or add fuel when the
engine is hot. Always loosen the fuel tank cap slowly to relieve
any pressure in the tank before fueling.
Always add fuel in a clean, well-ventilated outdoor area where
there are no sparks or flames. DO NOT smoke.
Never operate the unit without the fuel cap securely in place.
Avoid creating a source of ignition for spilled fuel. Wipe up any
spilled fuel from the unit immediately, before starting the unit.
Move the unit at least 30 ft. (9.1 m) from the fueling source and
site before starting the engine. DO NOT smoke.
Never start or run the unit inside a closed room or building.
Breathing exhaust fumes can kill. Operate this unit only in a well
ventilated outdoor area.
m
WHILE OPERATING

not wear loose clothing, jewelry, short pants, sandals or go
barefoot. Secure hair above shoulder level.
The cutting head shield must always be in place while operating
the unit. Do not operate the unit without both trimming lines
extended and the proper line installed. Do not extend the
trimming line beyond the length of the shield.
This unit has a clutch. The cutting head remains stationary when
the engine is idling. If it does not, take the unit to a Sears or
other qualified service dealer for an adjustment.
Adjust the handle to provide the best grip, if applicable.
Make sure the attachment is not in contact with anything before
starting the unit.
Use the unit only in daylight or good artificial light.

touch or try to stop moving parts.
Do not touch the engine, gear housing or muffler. These parts get
extremely hot from operation, even after the unit is turned off.
Do not operate the unit faster than the speed needed to do the job.
Do not run the unit at high speed when not inuse.
Do not force the unit. It will do a better, safer job when used at
the intended rate.

parts and accessories for this unit. Use of any other parts or
accessories could lead to serious injury to the user, or damage
to the unit, and void the warranty.
Keep the unit clean. Carefully remove vegetation and other
debris that could block moving parts.
To reduce fire hazard, replace a faulty muffler and spark arrestor.
Keep the engine and muffler free from grass, leaves, excessive
grease or carbon build up.

ADDING OIL: INITIAL USE
WARNING: OVERFiLLiNG THE CRANKCASE MAY
CAUSE SERIOUS PERSONAL iNJURY. Check the oil level
before each use. The importance of maintaining the proper
oil level cannot be overemphasized. Change the oil
according to the Maintenance Schedule.
NOTE: This unit was shipped without oil in the crankcase. Oil must
be added before starting the unit.
NOTE: This unit comes with a 2.03 fluid oz. (60 ml) bottle of oil.
1. Unscrew the top of the oil bottle. Remove the paper seal.
Reinstall the top of the oil bottle.
2. Remove the cap from the oil bottle. Cut the tip off the funnel
spout (Fig. 6).
3. Set the unit on a fiat, level surface.
4. Unscrew the oil fill plug (Fig. 7).
5. Pour the entire bottle into the oil fill hole (Fig. 7). DO NOT
overfill. Refer to Checking the Oil Level.
NOTE: Never add oil directly to the fuel tank. This unit has a four-
cycle engine. DO NOT mix oil with gasoline.
6. Wipe up any oil that may have spilled.
7. Reinstall the oil fill plug.
NOTE: Make sure the O-ring is in place on the oil fill plug (Fig. 7).
NOTE: Save the empty oil bottle. Use the bottle to measure the

USING THE RIGHT FUEL
The use of old fuel is the most common cause of performance
problems. Use only fresh, clean unleaded gasoline.
NOTE: This unit has a four-cycle engine. DO NOT mix oil with gasoline.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as
ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs
water. As little as 1% water in the fuel can make fuel and oil
separate, forming acids when stored. ALWAYS use fresh fuel (less
than 30 days old).
NOTE: Dispose of old fuel according to federal, state and local
regulations.
Using Blended Fuels
if using a blended fuel:
• Always use fresh unleaded gasoline
Use the fuel additive STA-BIL _ or an equivalent
Drain the tank and run the engine dry before storing the unit
!
I_ _WARNING: DO NOT USE E85 FUEL iN THiS UNIT. |
Using Fuel Additives
Use a fuel additive, such as STA-BIL Fuel Stabilizer or an
equivalent, to inhibit corrosion and minimize gum deposits. Add 0.8
oz. (23 ml) of fuel additive per gallon of fuel, according to the
instructions on the container. NEVER add fuel additives directly to
the unit's fuel tank.
FUELING THE UNiT

it has been proven that fuel containing greater than 10%
ethanol will likely damage this engine and void the warranty.
WARNING: Gasoline is extremely flammable, ignited
vapors may explode. Always stop the engine and allow it
to cool before filling the fuel tank. Do not smoke while
filling the tank. Keep sparks and open flames at a distance
from the area.
WARNING: Remove the fuel cap slowly to avoid injury
from fuel spray. Never operate the unit without the fuel cap
securely in place.
WARNING: Add fuel in a clean, well ventilated outdoor
area. Wipe up any spilled fuel immediately. Avoid creating
a source of ignition for spilled fuel. Do not start the engine
until fuel vapors dissipate.
