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 polarized 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.

GENERAL SAFETY INSTRUCTIONS
• Warning – To reduce the risk of electric shock - Use outdoor 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 footing on a solid surface enables better
control of the unit in unexpected situations.
• Do Not Overreach – Keep firm footing and balance. Overreaching 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 cord periodically, and if damaged, have
it repaired by an authorized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease. Failure to do so can cause
serious injury.
• Make sure all guards, straps, deflectors and handles are properly and securely attached.
• Never use flailing devices, wire, or rope on any attachment.
• Use only the manufacturer’s replacement string in the cutting head when using a string trimmer
attachment. Do not use any other cutting attachment, for example, metal wire, rope, or the like.
To install any other brand of cutting head to the string trimmer can result in serious personal
injury.
• Never operate unit without the grass deflector in place and in good condition.
• Check damaged parts – Before further use of the tool, a guard or other part that is damaged
should be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting and any other conditions that may affect its operation. A guard or other part that is
damaged must be properly repaired or replaced by an authorized service center to avoid risk

of personal injury.
• 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. or more above the ground.
• Store idle appliances - When not in use, power head should be stored indoors in a dry, locked
place out of the reach of children. Do not allow appliance to be used as a toy. Close attention is
necessary when used near children.
• Extension Cord - 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 14 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.
• Turn off controls before unplugging.
• Keep the air vents clean and free of debris to avoid overheating the motor. Clean after each
use.
• Stop the unit and disconnect the power source when not in use. Carry the unit with the motor
stopped.

• Do not hang unit so that the switch trigger is depressed.
• Do not use multiple cords.
• Do not abuse the cord – Never carry the unit by the extension cord or yank extension cord to
disconnect unit. Keep the cord clear of operator and obstacles at all times. Do not expose cords
to heat, oil, water, or sharp edges. Do not handle plug with wet hands.
• If the power supply cord is damaged, it must be replaced only by the manufacturer or by an
authorized service center to avoid risk.
• If appliance is not working as it should , has been dropped, damaged, dropped into water,
return it to service center.
• Don’t grasp the exposed cutting blades or cutting edges when picking up or holding the
appliance.
• Don’t Force Appliance – It will do the job better and with less likelihood of a risk of injury at the
rate for which it was designed.
• When operating the trimmer keep extension cord behind trimmer.
• Do not put any objects into openings. Do not use with any openings blocked, keep free of dust,
lint, hair and anything that may reduce air flow.
