hard materials such as re‑bar may be hazardous as well.
Tighten the side handle securely before use.
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.

Additional Safety Information


WARNING: Never modify the power tool or any part of
it. Damage or personal injury could result.

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 the State of California 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.
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. Direct particles away from face and body.
Use the appropriate dust extractor vacuum to remove
•
the vast majority of static and airborne dust. Failure
to remove static and airborne dust could contaminate the
working environment or pose an increased health risk to
the operator and those in close proximity.
Use clamps or other practical ways 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 and injury.

Air vents often cover moving parts and should be
•
avoided. Loose clothes, jewelry or long hair can be caught
in moving parts.

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.
