SPARK ARRESTOR NOTE
NOTE: For users on U.S. Forest Land and in the states of
California, Maine, Oregon and Washington. All U.S. Forest Land
and the state of California (Public Resources Codes 4442 and
4443), Oregon and Washington require, by law that certain internal
combustion engines operated on forest brush and/or grass-covered
areas be equipped with a spark arrestor, maintained in effective
working order, or the engine be constructed, equipped and
maintained for the prevention of fire. Check with your state or local
authorities for regulations pertaining to these requirements. Failure
to follow these requirements could subject you to liability or a fine.
This unit is factory equipped with a spark arrestor. If it requires
replacement, ask your Sears or other qualified service dealer to
install the Accessory Part #753-05631 Muffler Assembly.

SPECIAL SAFETY WARNINGS FOR GAS ENGINES
vapors can explode if ignited. Take the following
WARNING: Gasoline is highly flammable, and its
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 fuel tank.
Never remove the cap of the fuel tank, or add fuel, when the engine
is hot. Never operate the unit without the fuel cap securely in place.
Loosen the fuel tank cap slowly to relieve any pressure in the tank.
• Add fuel in a clean, well-ventilated area outdoors where there are
no sparks or flames. Slowly remove the fuel cap only after
stopping engine. Do not smoke while fueling. Wipe up any spilled
fuel from the unit immediately.
• Avoid creating a source of ignition for spilled fuel. Do not start
the engine until fuel vapors dissipate.
• Move the unit at least 30 feet (9.1 m) from the fueling source and site
before starting the engine. Do not smoke. Keep sparks and open
flames away from the area while adding fuel or operating the unit.
WHILEOPERATING
• 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.

• Avoid accidental starting. Be in the starting position whenever
pulling the starter rope. The operator and unit must be in a stable
position while starting. Refer to Starting/Stopping Instructions.
• Do not set unit on any surface except a clean, hard area while
engine is running. Debris such as gravel, sand, dust, grass, etc.
could be picked up by the air intake and thrown out by the
discharge opening, damaging unit, property, or causing serious
injury to bystanders or operator.
• Use the right tool. Only use this tool for its intended purpose.
• Do not force unit. It will do the job better and with less likelihood

grease or carbon build up.
• Turn the engine off and disconnect the spark plug for maintenance
or repair.
• Never point the blower or blowing debris in the direction of people,
animals, or in the direction of windows. Always direct the blowing
debris away from people, animals, and windows. Use extra caution
when blowing debris near solid objects such as trees, automobiles,
walls, etc.
OTHER SAFETY WARNINGS
• Always disconnect the spark plug before performing maintenance
or accessing movable parts. See Replacing the Spark Plug.
• Never store the unit, with fuel in the tank, inside a building where
fumes may reach an open flame (pilot lights, etc.) or sparks
(switches, electrical motors, etc.).

SPECIAL NOTE: Exposure to vibrations through prolonged use of
gasoline powered hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of people prone to
circulation disorders or abnormal swelling. Prolonged use in cold
weather has been linked to blood vessel damage in otherwise
healthy people. If symptoms occur such as numbness, pain, loss
of strength, change in skin color or texture, or loss of feeling in the
fingers, hands or joints, discontinue use of this tool and seek
medical attention. A reduced vibration system does not guarantee
avoidance of these problems. Users who operate power tools on a
regular basis must closely monitor their physical condition and the
condition of this tool.

OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for the unit
not running properly. Be sure to use fresh, clean unleaded fuel.
Follow the instructions carefully for the proper fuel/oil mixture.
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. It forms acids when stored. When using alcohol-blended
fuel, use fresh fuel (less than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable,
follow recommended precautions:
• Always use the fresh fuel mix explained in your operator's
manual
• Always agitate the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the unit
Using Fuel Additives
reliability, pay strict attention to the oil and fuel mixing
I_ AUTION: For proper engine operation and maximum
The bottle of 2-cycle oil that came with your unit contains a fuel
additive which will help inhibit corrosion and minimize the formation
of gum deposits. It is recommended that you use our 2-cycle oil
with this unit. If unavailable, use a good 2-cycle oil designed for
air-cooled engines along with a fuel additive, such as STA-BIL®
Gas Stabilizer or an equivalent. 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.
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded
gasoline in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix
them directly in the engine fuel tank. See the table below for
specific gas and oil mixing ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with one

• The unit is in good working condition.
• The tubes are in place and secure.
OPERATING TIPS
I_ ARNING: To prevent serious personal injury or
• Assure the unit is not directed at anybody or any loose debris
before starting the unit.
• Verify that the unit is in good working condition. Make sure the
tubes are in place and secure.
• Always hold the unit securely when operating.
• To reduce the risk of hearing loss associated with sound level(s),
hearing protection is required.
• Operate power equipment only at reasonable hours-- not early in the
morning or late at night when people might be disturbed. Comply
with times listed in local ordinances. Usual recommendations are 9:00
am to 5:00 pm, Monday through Saturday.
• To reduce noise levels, limit the number of pieces of equipment
used at any one time.
• To reduce noise levels, operate power blowers at the lowest
possible speed to do the job.
• Check your equipment before operation, especially the muffler,
air intakes and air filters.
• Use rakes and brooms to loosen debris before blowing.
• In dusty conditions, slightly dampen surfaces.
• Conserve water by using power blowers instead of hoses for
many lawn and garden applications, including areas such as
screens, patios, grills, porches, and gardens.
• Watch out for children, pets, open windows or freshly washed
cars, and blow debris safely away.
• Use the full blower nozzle extension so the air stream can work
close to the ground.
• Clean up after using blowers and other equipment. Dispose of
debris appropriately.
• Use the trigger lock (Fig. 11, B) to keep the trigger depressed
while operating to make continuous operation easier.
