• Use auxiliary handles supplied with the tool. Loss of control can cause
personal injury. 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.
• 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. It is recommended that the side handle be
used at all times. 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.
• Wear gloves when operating tool or changing bits. Accessible metal parts on
the tool and bits may get extremely hot during operation. Small bits of broken
material may damage bare hands.
• 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.
• Keep the power cord away from the rotating bit. Do not wrap the cord around
any part of your body. An electric cord wrapped around a spinning bit may
cause personal injury and loss of control.
NOTE: Do not overheat the bit (discoloration) while grinding a new edge. Badly worn
chisels require reforging. Do not reharden and temper the chisel.
WARNING: ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety
glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
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: 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. Wear protective clothing and wash
exposed areas with soap and water. Allowing dust to get into your mouth, eyes,
or lay on the skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause
serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved
respiratory protection appropriate for the dust exposure. Direct particles away from
face and body.
WARNING: Always use eye protection. All users and bystanders must wear eye
protection that conforms to ANSI Z87.1.
CAUTION: When not in use, place tool on its side on a stable surface where it
will not cause a tripping or falling hazard. Some tools with large battery packs will
stand upright on the battery pack but may be easily knocked over.
