c) 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 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.
6) SERVICE
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
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.
• Wear safety goggles or other eye protection. Hammering
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.
• Do not operate this tool for long periods of time. 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.
• Slightly worn chisels can be resharpened by grinding.
• Do not overheat the bit (discoloration) while grinding a new
edge. Badly worn chisels require reforging. Do not reharden and
temper the chisel.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
