gases, or dust. Power tools create sparks which may ignite the dust or fumes.
Do not allow children or untrained individuals to use this unit.
Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
Do not handle plug or tool with wet hands.
Never allow children to operate the equipment. Never allow adults to operate the equipment without
proper instruction.
Always wear safety glasses with side shields. Everyday glasses have only impact resistant lenses.

operation is dusty.
Wear eye protection when operating this product. Secure long hair above shoulder level to prevent
entanglement in moving parts.
Do not expose to rain, store indoors.
Do not operate in poor lighting.
Keep all parts of your body away from any moving part.

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 only identical manufacturer’s replacement parts and accessories. Use of any other parts may
create a hazard or cause product damage.
Do not charge battery tool in rain, or damp or wet location. Follow this rule will reduce the risk of
electric shock.
For household use only.
Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in

changing accessories. Following this rule will reduce the risk of electric shock, fire, or serious
personal injury.
Remove or disconnect battery before servicing, cleaning or removing material from the gardening

place out of the reach of children.
Do not dispose of the batteries in a fire. The cell may explode. Check with local codes for possible
special disposal instructions.

eyes or skin. It may be toxic if swallowed.
Do not place battery tools or their batteries near fire or heat. This will reduce the risk of explosion
and possibly injury.
Batteries can explode in the presence of a source of ignition, such as a pilot light. To reduce the risk
of serious personal injury, never use any cordless product in the presence of open flame. An
exploded battery can propel debris and chemicals. If exposed, flush with water immediately.
Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has been
dropped or received a sharp blow. A damaged battery is subject to explosion. Properly dispose of a
dropped or damaged battery immediately.
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. 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.
For best results, your battery tool should be charged in a location where the temperature is more than
45°F but less than 104°F. To reduce the risk of serious personal injury, do not store outside or in
vehicles.
Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in
contact with your skin, wash immediately with soap and water, then neutralize with lemon juice or
vinegar. If liquid gets into your eyes, flush them with clean water for at least 10 minutes, then seek
immediate medical attention. Following this rule will reduce the risk of serious personal injury.
