SPECIAL SAFETY WARNINGS FOR GAS ENGINES
WARNING: Gasoline is highly flammable, and its
vapors can explode if ignited. Take the following
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.
WHILE OPERATING
• Never start or run the unit inside a closed room or building.
Breathing exhaust fumes can kill. Operate this unit only in a wellventilated outdoor area.

RULES FOR SAFE OPERATION
Use the unit only in daylight or good artificial light.
Keep outside surfaces free from oil and fuel.
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
of injury at a rate for which it was designed.
Do not overreach or use from unstable surfaces such as ladders,
trees, steep slopes, rooftops, etc. Always keep proper footing
and balance.
Always hold the unit with a firm grip when operating.
Keep hands, face, and feet away from all moving parts. Do not
touch or try to stop the impeller when it is rotating. Do not
operate without guards in place.
Do not put any object into openings. Do not use with any
opening blocked; keep free of dirt, debris, and anything that may
reduce the air flow.
Do not touch the engine or muffler. These parts get extremely
hot from operation, even after the unit is turned off.
Do not operate the engine faster than the speed needed to do
the job. Do not run the engine at high speed when not in use.
Always stop the engine when operation is delayed or when
walking from one location to another.
Stop the engine for maintenance, repair, to install or remove the
blower tubes. The unit must be stopped and the impeller no
longer turning to avoid contact with the rotating blades.
If you strike or come into contact with a foreign object, stop the
engine immediately and check for damage. Do not operate
before repairing damage. Do not operate the unit with loose or
damaged parts.
Use only replacement parts or accessories recommended for
this tool that are distributed by Sears or a Craftsman outlet. Use
of any replacement parts or accessories purchased elsewhere
may be hazardous, and will also void your warranty.
Never use this unit for spreading chemicals, fertilizers or other
substances which may contain toxic materials.
• To reduce fire hazard, replace faulty muffler and spark arrestor.
Keep the engine and muffler free from grass, leaves, excessive
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.).
• Allow the engine to cool before storing or transporting. Be sure
to secure the unit while transporting.
• Store the unit in a dry place, secured, or at a height to prevent
unauthorized use or damage. Keep out of the reach of children.
• Never douse or squirt the unit with water or any other liquid.
Keep handles dry, clean, and free from debris. Clean after each
use, see Cleaning and Storage instructions.

these instructions to them.
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.

RECOMMENDED FUEL TYPE
Old fuel Is the primary reason for Improper unit performance. Be
sure to use fresh, clean, unleaded gasoline.
NOTE: This Is a four-cycle engine. In order to avoid damage to the
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 or form acids when stored. Use fresh fuel (less than 60
days old), when using alcohol-blended fuel.
Using Biended Fueis
If you choose to use a blended fuel, or Its use Is unavoidable,
follow recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL® or an equivalent
• Drain tank and run the engine dry before storing unit
Using Fuei Additives

WARNING: Gasoline is extremely flammable. Ignited
A
The use of fuel additives, such as STA-BIL® Gas Stabilizer or an
equivalent, will inhibit corrosion and minimize the formation of gum
deposits. Using a fuel additive can keep fuel from forming harmful
deposits in the carburetor for up to six (6) months. 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 gas tank.

OPERATING TIPS
WARNING: To prevent serious personal injury or
damage to the unit, make sure blower tubes are in
place before you operate the unit.
• 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 or use a mister
attachment when water is available.
• 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. 16) to keep the trigger depressed while
operating to make continuous operation easier.
APPLICATIONS
1 Use the blower for trees, shrubs, flower beds and hard-to-
clean areas.
