1) Workplace safety
a) Keep your work area clean and well lit. Untidy or badly lit work areas can lead to accidents.
b) Do not work with the power tool in a potentially explosive environment containing flammable
liquids, gases or dust. Power tools produce sparks that can ignite dust or vapours.
c) Keep children and other persons away while using the power tool. If you are distracted, you can lose
control of the power tool.
2) Electrical safety
a) The connecting plug of power tools must fit into the socket. The plug must not be modified in any
way. Do not use adapter plugs together with earthed power tools. Unmodified plugs and matching
sockets reduce the risk of electric shock.
b) Avoid physical contact with earthed surfaces such as pipes, heaters, stoves and refrigerators.
There is an increased risk of electric shock if your body is earthed.
c) Keep power tools away from rain and damp. The penetration of water into a power tool increases the
risk of electric shock.
d) Do not misuse the connecting cable by carrying or hanging the power tool from it or pulling the
plug out of the socket with it. Keep the connecting cable away from heat, oil, sharp edges or
moving parts. Damaged or tangled up connecting cables increase the risk of electric shock.
e) If you are working with a power tool outdoors, only use extension cables that are suitable for
outdoor use. The use of an extension cable suitable for outdoor use reduces the risk of electric shock.
f) If operation of the power tool in a humid environment is unavoidable, use a residual current circuit
breaker. The use of a residual current circuit breaker reduces the risk of electric shock.
3) Personal safety
a) Be attentive, pay attention to what you are doing, and go about your work with a power tool using
common sense. Do not use a power tool if you are tired or under the influence of alcohol, drugs or
medicines. A moment of carelessness when using the power tool can lead to serious injury.
b) Wear personal protective equipment and always use protective goggles. Wearing personal protective
equipment, such as a dust mask, non-slip safety shoes, safety helmet or ear protection reduces the risk of
injury, depending on the type and use of the power tool.
c) Avoid starting up unintentionally. Make sure the power tool is turned off before connecting, picking
up or carrying it to the power supply and/or battery. If you have your finger on the switch when carrying
the power tool or if you connect the power tool to the power supply when it is switched on, this can lead to
accidents.
d) Remove adjustment tools or wrenches before turning on the power tool. A tool or key located in a
rotating part of the power tool can cause injury.
e) Avoid awkward body positions. Ensure a safe working stance and keep your balance at all times.
This allows you to better control the power tool in unexpected situations.
f) Wear appropriate clothing. Do not wear loose clothing or jewellery. Keep hair and clothing away
from moving parts. Loose clothing, jewellery or long hair can be caught by moving parts.
g) If dust extraction and collection devices can be fitted, they must be connected and used correctly.
The use of a dust extraction system can reduce the risk of dust.
h) Do not lull yourself into false safety and do not ignore the safety rules for power tools, even if you
are familiar with the power tool after many uses. Careless actions can lead to serious injuries within
fractions of a second.
4) Use and handling of the power tool
a) Do not overload the power tool. Use the appropriate power tool for your work. With the right power
tool you can work more effectively and safely in the specified power range.
b) Do not use power tools if their switch is defective. A power tool that can no longer be switched on or off
is dangerous and must be repaired.
c) Disconnect the plug from the socket and/or remove a detachable battery before making unit
adjustments, changing insert tool parts, or putting the power tool away. This precaution prevents the
unintentional start of the power tool.
d) Keep unused power tools out of the reach of children. Do not allow anyone to use the power tool
who is not familiar with it or who has not read these instructions. Power tools are dangerous if they
are used by inexperienced persons.
e) Maintain power tools and insert tools with care. Check that moving parts function correctly and do
not jam. Also check whether parts are broken or damaged in such a way that the function of the
