GENERAL POWER TOOL SAFETY WARNINGS
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired
or under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in serious personal
injury.
b) Use personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate conditions will reduce personal
injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position
before connecting to power source and/or battery pack, picking up or
carrying the tool. Carrying power tools with your finger on the switch or
energising power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and
collection facilities, ensure these are connected and properly used. Use
of dust collection can reduce dust-related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the
rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and must
be repaired.
c) Disconnect the plug from the power source and/or the battery pack from
the power tool before making any adjustments, changing accessories,
or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
WARNING! Read all safety warnings and all instructions Failure to follow
the warnings and instructions may result in electric shock, fire and/or
serious injury.
The term “power tool” in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR
FUTURE REFERENCE
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords increase the risk of electric
shock.
e) When operating a power tool outdoors, use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
2
Extension Cords
d) Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to operate
the power tool. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the
power tool’s operation. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits, etc. in accordance with
these instructions, taking into account the working conditions and the
work to be performed. Use of the power tool for operations different from
those intended could result in a hazardous situation.
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
tool is maintained.
CAUTION: Use only extension cords that are approved by the country’s
Electrical Authority. Before using extension cords, inspect them for loose or
exposed wires, damaged insulation and defective fittings. Replace the cord if
necessary.
Additional Safety Warnings for Demolition Hammers
• Wear ear protectors. Exposure to noise can cause hearing loss.
• Use auxiliary handles 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 operator an electric shock.
• Be certain that the material being drilled does not conceal electric or
gas service and that their locations have been verified with the utility
companies.
• 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.
• Ensure the chisel is secured in place before operating the tool.
• In cold-weather conditions or when the tool has not been used for a longer
period of time, let the tool run with no load for several minutes before use.
• When working above ground level ensure the area below is clear.
• Do not touch the chisel or the parts close to the chisel immediately after
operation, as they may be extremely hot and cause burns to the skin.
• Always direct the power cable to the rear, away from the chisel.
• 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.
• Air vents often cover moving parts and should be avoided. Loose clothes,
jewelry or long hair can be caught in moving parts.
WARNING: We recommend the use of a residual current device with a residual
current rating of 30mA or less.
Electrical Safety
The electric motor has been designed for one voltage range only. Always check that
the power supply corresponds to the voltage on the rating plate. 220–240 V AC
means your tool will operate on alternating current. Operation at a voltage outside
this range can cause loss of power and can result in overheating. All DEWALT
tools are factory tested; if this tool does not operate, check the power supply. Your
DEWALT tool is double insulated, therefore no earth wire is required.
