General power tool safety warnings
Warning! Read all safety warnings, instruc-
tions, illustrations and specifications
provided with power tool. Failure to follow
the warnings and instructions listed below may
result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in all of the warnings listed below refers
to your mains operated (corded) power tool or battery oper-
ated (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
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
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
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
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
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
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
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.
h. Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool
safety principles. A careless action can cause severe
injury within a fraction of a second.
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
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
ENGLISH (Original instructions)
these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
e. Maintain power tools and accessories. Check for
misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the
power tools 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.
h. Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and greasy
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
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.
Additional power tool safety warnings
