5} SERVICE
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power too/is maintained.
Additional Safety Rules for Heavy Duty
Rotary Hammers
• Wear ear protectors. Exposure to noise can cause hearing loss.
• Use auxiliary handle(s), if supplied with the tool. Loss of
control can cause personal injury.
• Hold power tools by insulated gripping surfaces when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of the
power tool "live" and could give the opeartor an electric shock.
• 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.
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.
• Neverlay the tooldown untilthe bithas 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.
• 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 persona/injury and loss
of control.
• Do not overheat the bit (discoloration) while grinding a new
edge. Badly worn chisels require reforging. Do not reharden and
temper the chisel
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
• 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
