• 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. 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.
• Slightly worn chisels can be resharpened by grinding.
NOTE: Do not overheat the bit (discoloration) while grinding a
new edge. Badly worn chisels require reforging. Do not reharden
and temper the chisel.
• 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.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewellery 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.
