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.
• 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. Tighten the side handle securely before use.
• Ensure the chisel is secured in place before operating the
tool.
• In cold-weather conditions or when the tool has not been used
for a longer period of time, let the tool run with no load for several
minutes before use.
• When working above ground level ensure the area below is
clear.
• Do not touch the chisel or the parts close to the chisel
immediately after operation, as they may be extremely hot
and cause burns to the skin.
• Always direct the power cable to the rear, away from the
chisel.
• 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.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
• An extension cord must have adequate wire size for safety.
An undersized cord will cause a drop in line voltage resulting in loss
of power and overheating. When using more than one extension
to make up the total length, be sure each individual extension
contains at least the minimum wire size. The following table shows
the correct size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The smaller
the gauge number, the heavier the cord

WARNING: 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 from these exposures 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 those dust masks that are specially designed to
filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
