READ ALL INSTRUCTIONS
For safe operation, read and understand all instructions
before using this product. Follow all safety instructions.
Failure to follow all safety instructions listed below, can
result in serious personal injury.
Do not allow children or untrained individuals to use this
unit.

Wear eye protection which is marked to comply with ANSI
Z87.1 when operating this product.
Alwa y s wea r safet y glas s e s wit h side shiel d s .
Everyday glasses have only impact resistant lenses. They
are NOT safety glasses. Following this rule will reduce the
risk of eye injury. Use face mask if operation is dusty.
Wear heavy, long pants, boots, and gloves. Do not wear
loose fitting clothing, short pants, or go barefoot. Do not
wear jewelry of any kind.
Secure long hair above shoulder level to prevent entan-
glement in moving parts.
Keep all bystanders, children, and pets at least 50 ft.
away.
Do not operate this unit when you are tired, ill, or under
the influence of alcohol, drugs, or medication.
Do not operate in poor lighting.
Keep all parts of your body away from any moving part.
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking and work practices
are all thought to contribute to the development of these
symptoms. It is presently unknown what, if any, vibrations
or extent of exposure may contribute to the condition.
There are measures that can be taken by the operator to
possibly reduce the effects of vibration:
a) Keep your body warm in cold weather. When
operating the unit wear gloves to keep the
hands and wrists warm. It is reported that
cold weather is a major factor contributing to
Raynaud’s Syndrome.
b) After each period of operation, exercise to
increase blood circulation.
c) Take frequent work breaks. Limit the amount
of exposure per day.
d) Keep the tool well maintained, fasteners tight
ened and worn parts replaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician about
these symptoms.
Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases, or
dust. Power tools create sparks which may ignite the dust
or fumes.
To reduce the risk of electric shock, this tool has a po-
larized plug (one blade is wider than the other) and will
require the use of a polarized extension cord. The plug
will fit into a polarized extension cord only one way. If the
plug does not fit fully into the extension cord, reverse the
plug. If the plug still does not fit, obtain a correct polarized
extension cord. A polarized extension cord will require
the use of a polarized wall outlet. This plug will fit into the
polarized wall outlet only one way. If the plug does not fit
fully into the wall outlet, reverse the plug. If the plug still
does not fit, contact a qualified electrician to install the
proper wall outlet. Do not change the equipment plug,
extension cord receptacle, or extension cord plug in any
way.
Avoid body contact with grounded surfaces such as
radiators, ranges, and refrigerators. There is an increased
risk of electric shock if your body is grounded.
Don’t expose power tools to rain or wet conditions. Wa-
ter entering a power tool will increase the risk of electric
shock.
Use outdoor extension cords marked W-A, W,
SOW-A, STW-A, STOW-A, SJW-A, SJTW-A, or SJTOWA.
These cords are rated for outdoor use and reduce the
risk of electric shock.
Ground Fault Circuit Interrupter (GFCI) protection should
be provided on the circuit(s) or outlet(s) to be used for the
gardening appliance. Receptacles are available having
built-in GFCI protection and may be used for this measure
of safety.
Do not force tool. Use the correct tool for your applica-
tion. The correct tool will do the job better and safer at
the rate for which it is designed.
Do not operate the equipment while barefoot or when
wearing sandals or similar lightweight footwear. Wear
protective footwear that will protect your feet and improve
your footing on slippery surfaces.
Keep firm footing and balance. Do not overreach. Over-
reaching can result in loss of balance.
Avoid accidental starting. Be sure the switch trigger is not
engaged before plugging in.

IMPORTANT SAFETY INSTRUCTIONS
Do not use tool if switch trigger does not turn it on or off.
Any tool that cannot be controlled with the switch trigger
is dangerous and must be repaired.
Disconnect the plug from power source before storing the
tool. Such preventive safety measures reduce the risk of
starting the tool accidentally.
SPECIFIC SAFETY RULES
SPECIFIC SAFETY RULES FOR TRIMMER USE
Replace string head if cracked, chipped, or damaged
in any way. Be sure the string head or blade is properly
installed and securely fastened. Failure to do so can cause
serious injury.
Make sure all guards, straps, deflectors and handles are
properly and securely attached.
Use only the manufacturer’s replacement string in the
cutting head. Do not use any other cutting attachment,
for example, metal wire, rope, or the like. To install any
other brand of cutting head to this string trimmer can
result in serious personal injury.
Never operate unit without the grass deflector in place
and in good condition.
Maintain a firm grip on both handles while trimming.
Keep string head below waist level. Never cut with the
string head located over 30 in. (76 cm) or more above
the ground.
� Use only identical manufacturer’s replacement parts and
accessories. Use of any other parts may create a hazard
or cause product damage.
When not in use, string trimmer should be stored indoors
in a dry, locked place out of the reach of children.
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. A wire
gauge size (A.W.G.) of at least 16 is recommended for an
extension cord 50 feet or less in length. A cord exceeding 100 feet is not recommended. If in doubt, use the
next heavier gauge. The smaller the gauge number, the
heavier the cord. An undersized cord will cause a drop in
line voltage resulting in loss of power and overheating.
Save these instructions. Refer to them frequently and
use them to instruct others who may use this trimmer. If
you loan someone this unit, loan them these instructions
also.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks
that are specially designed to filter out microscopic particles.
