GENERAL POWER TOOL SAFETY WARNINGS
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.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-
3) Personal safety
operated (corded) power tool or battery-operated (cordless)
power tool.
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.
4) Power tool use and care
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
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.
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.
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.
