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.

Check the work area before each use. Remove all objects
such as rocks, broken glass, nails, wire, or string which
can be thrown or become entangled in the machine.

Use Safety Glasses – Always wear eye protection with
side shields marked to comply with ANSI Z87.1. Failure
to do so could result in objects being thrown into your
eyes, resulting in possible serious injury.

Always wear safety glasses with side shields. 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.

Dress Properly – Use rubber gloves and substantial
footwear is recommended when working outdoors. Wear
heavy long pants, long sleeves, boots, and gloves. Do not
wear loose-fitting clothing, short pants, sandals, jewelry
of any kind, or go barefoot.

Secure long hair above shoulder level to prevent entangle-
ment in moving parts.

Keep children away – Keep all bystanders, children, and
pets at least 50 ft. away.

Stay alert – 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.

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 pipes,
radiators, ranges, and refrigerators. There is an increased
risk of electric shock if your body is grounded.

Avoid Dangerous Environments – Don’t expose power
tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
 Warning – To reduce the risk of electric shock - Use out-
door extension cords marked W-A, W, SW-A, SOW-A,
STW-A, STOW-A, SJW-A, SJTW-A, or SJTOW-A. 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.
 Use Right Appliance - Do not force tool. Use the correct
tool for your application. 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.
 Do not use on a ladder or unstable support. Stable foot-
ing on a solid surface enables better control of the unit
in unexpected situations.

Do Not Overreach – Keep firm footing and balance. Over-
reaching can result in loss of balance.
 Avoid Unintentional Starting – Do not carry plugged in
appliance with finger on trigger. Be sure the switch trigger
is not engaged before plugging in.

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 Appliance – Remove appliance from power
source before storing, servicing, changing accessories
such as cutting line. Such preventive safety measures
reduce the risk of starting the tool accidentally.


Use only identical manufacturer’s replacement parts and
accessories. Use of any other parts may create a hazard
or cause product damage.
 Maintain appliance with care – Replace string head if
cracked, chipped, or damaged in any way. Be sure the
string head is properly installed and securely fastened.
Keep cutting edge sharp and clean for best performance
and to reduce the risk of injury. Follow instructions for
lubricating and changing accessories. Inspect appliance
