Wear safety goggles or other eye protection. Hammering and
drilling operations cause chips to fly. Flying particles can cause per-
manent eye damage.
Always use the side handle supplied with the tool. Keep a firm
grip on the tool at all times. Do not attempt to operate this tool with-
out 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 be hazardous as well.
Do not use chisels in any of the rotation modes. Chisels may
jam causing loss of control.
Wear gloves when handling hammer bits and tools. Hammer
bits and tools get hot during operation. Gloves and frequent rest
periods will reduce the risk of vibration damage to hands and arms.
Keep gloves away from rotating bits to avoid entanglement
with bit and possible injury.
Keep hands and body from between the tool and wall or post,
etc., to avoid being crushed by the tool should it twist unexpectedly
if the bit binds.
CAUTION: Wear appropriate personal hearing protection dur-
ing 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 exam-
ples 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 equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.
