contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of the
power tool "live" and shock the operator.
• 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 beforeoperating 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.
• An extension cord must have adequate wire size (AWG
or American Wire Gauge) for safety. The smaller the gauge
number of the wire, the greater the capacity of the cable, that
is 16 gauge has more capacity than 18 gauge. 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: Always use eye protection. All users and
bystanders must wear eye protection that conforms to ANSI Z87.1.
WARNING: Always wear proper personal hearing protection
that conforms to ANSI S12.6 (S3.19) during use. Under some
conditions and duration of use, noise from this product may
contribute to hearing loss.
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 (CCA).
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
