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 operating in dusty work spaces.
• Avoid Dangerous Environment — Don’t expose power tools to damp or wet conditions. Water
entering a power tool will increase the risk of electric shock.
• Don’t use in rain.
• Keep all bystanders, children, and pets at least 50 ft. away.
• Do not use the power tools for any job except that for which it is intended.
• Avoid Unintentional Starting – Do not carry string trimmer with fingers on the switch. Be sure
the battery is removed while transporting.

• Stay alert - Watch what you are doing. Use common sense. Do not operate this unit when you
are tired, ill or under the influence of alcohol, drugs or medication.
• Always store idle power tools indoors - When not in use, power tools should be stored indoors
in a dry place, out of reach of children.
• Power tool maintenance – 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.
• Check Damaged Parts – Before further use of the appliance, 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, damaged mountings, and any other condition that may affect its operation. A guard or
other part that is damaged should be properly repaired or replaced by an authorized service
center unless indicated elsewhere in this manual.
• Do not charge or operate cordless tools in damp or wet locations or in the rain. Following this
rule will reduce the risk of electric shock.

important safety instructions
• Do not dispose of the batteries in a fire. The cells may explode. Check with local codes for
possible special disposal instructions.
• Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause
damage to the eyes or skin. It may be toxic if swallowed.
• Exercise care in handling batteries in order not to short the battery with conducting materials
such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns.
• Dress Properly – Do not wear loose clothing or jewelry. They can be caught in moving parts.
Use of rubber gloves and substantial footwear is recommended when working outdoors. Wear
protective hair covering to contain long hair.
• Do not add unnecessary force to your power tool – It will do the job better and with less
likelihood of a risk of injury at the rate for which it was designed.
• Recharge only with the charger specified by the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fire when used with another battery pack.
• For use only with (2901302, 2902402) battery. For use only with (2901402, 2903702) charger.
• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects, that can make a connection from one terminal
to another. Shorting the battery terminals together may cause a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or burns.
• Do not use a battery pack or appliance that is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or power tools to fire or excessive temperature. Exposure to fire
or temperature above 265°F (130°C) may cause explosion.
W A R N I N G (PROPOSITION 65)
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 of exposure to these chemicals 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 dust masks that are specially designed to filter out microscopic
particles.
