operations cause chips to fly. Flying particles can cause permanent
eye damage. Wear a dust mask or respirator for applications that
generate dust. Ear protection may be required for most applications.
•
Keep a firm grip on the tool at all times. Do not attempt
to operate this tool without holding it with both hands.
Operating this tool with one hand will result in loss of control.
Breaking through or encountering hard materials such as re-bar
may be hazardous as well.

Vibration
caused by hammer action may be harmful to your hands and arms.
Use gloves to provide extra cushion and limit exposure by taking
frequent rest periods.
• Do not recondition bits yourself.
Chisel reconditioning should
be done by an authorized specialist. Improperly reconditioned
chisels could cause injury.
• Accessories and tool may get hot during operation.
Wear gloves when handling them if performing heat producing
applications such as hammerdrilling and drilling metals.
• Never lay the tool down until the bit has come to a complete
stop.
Moving bits could cause injury.
• Do not strike jammed bits with a hammer to dislodge
them.
Fragments of metal or material chips could dislodge and
cause injury.

or other small metal objects that can make a connection
from one terminal to another.
Shorting the battery terminals
together may cause burns or a fire.
d)
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.

Additional Safety Instructions for Rotary
Hammers
• Wear ear protectors.
Exposure to noise can cause hearing loss.
• Use auxiliary handle(s), if supplied with the tool.
Loss of
control can cause personal injury.
•
Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring.
Cutting accessory contacting a “live” wire
may make exposed metal parts of the power tool “live” and could
give the operator an electric shock.
• Be certain that the material being drilled does not conceal
electric or gas service and that their locations have been
verified with the utility companies.
•
Use clamps or other practical way to secure and support
the workpiece to a stable platform.
Holding the work by hand
or against your body is unstable and may lead to loss of control.
