• Do not operate power tools in
explosive atmospheres, such as in the
presence of flammable liquids, gases
or dust. Electrical tools create sparks,
which may ignite dust or vapours.
• Keep children and uninvolved
bystanders away while operating a
power tool. Distractions can cause
you to lose control of the device.
• Ensure sufficient ventilation. Stale,
odourintensive air can cause tiredness.
Electrical safety
• Power tool plugs must match the
outlet. Never modify the plug in
any way. Do not use an adapter
plug in conjunction with protective-
earth devices. Unmodified plugs
and matching outlets reduce risk of
electric shock.
• 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.
• Do not expose power tools to rain
and wet conditions. Water entering
a power tool will increase the risk of
electric shock.
• Do not misuse the cable by using it
to carry the power tool, to hang it up
or to pull the plug out of the socket.
Keep the cable away from heat, oil,
sharp edges and moving device
parts. Damaged or entangled cords
increase the risk of electric shock.
• When operating a power tool
outdoors, only use an extension
cord that is also suitable for
outdoor use. The use of a suitable
5451920-Ruehrwerk_man.indd 43
extension cord for outdoor use will
reduce the risk of an electric shock.
• When operating a power tool in a
damp location is unavoidable, use
a residual current protective device
(RCD). Use of an RCD reduces the
risk of electric shock.
Personal safety
• Be careful and ensure that you pay
attention to what you are doing and
make sure you are using the power
tool sensibly. Do not use power
tools when you are tired, or under
the influence of drugs, alcohol or
prescription drugs. A moment of
inattention while operating power
tools may result in serious personal
injury.
• Use personal safety equipment
and always wear goggles. Safety
equipment such as a dust mask, non
slip safety shoes, hard hat or hearing
protection, according to the type
of power tool and the purpose, will
reduce the risk of personal injuries.
• Avoid switching on accidentally.
Ensure that the power tool is
switched off before you connect
it to the power supply/battery or
carry it anywhere. Carrying power
tools with your finger on the switch or
plugging in power tools that have the
switch on invites accidents.
• 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
device may result in personal injury.
• Avoid unnatural body positions.
Ensure that you are standing
securely and keep your balance at
