2 Safety
2.1 General power tool safety warnings
WARNING Read all safety warnings, instructions, illustrations and
specifications provided with this power tool. Failure to follow all instruc-
tions 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 the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
Work area safety
▶Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
▶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.
▶Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
Electrical safety
▶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.
▶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 or wet conditions. Water entering a
power tool will increase the risk of electric shock.
▶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.
▶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.
▶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.
Printed: 23.05.2019 | Doc-Nr: PUB / 5396155 / 000 / 01

Personal safety
▶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.
▶Use personal protective equipment. Always wear eye protection.
Protective equipment such as a dust mask, non-skid safety shoes, hard
hat or hearing protection used for appropriate conditions will reduce
personal injuries.
▶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.
▶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.
▶Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
▶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.
▶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.
▶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.
Power tool use and care
▶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.
▶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.
▶Disconnect the plug from the power source and/or remove the
battery pack, if detachable, 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.
▶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.
Printed: 23.05.2019 | Doc-Nr: PUB / 5396155 / 000 / 01

▶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 tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are caused by poorly
maintained power tools.
▶Keep cutting tools sharp and clean. Properly maintained cutting tools
with sharp cutting edges are less likely to bind and are easier to control.
▶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.
▶Keep handles and grasping surfaces dry, clean and free from oil and
grease. Slippery handles and grasping surfaces do not allow for safe
handling and control of the tool in unexpected situations.
Battery tool use and care
▶Recharge only with the charger specified by the manufacturer. A
charger that is suitable for one type of battery pack may create a risk of
fire when used with another battery pack.
▶Use power tools only with specifically designated battery packs. Use
of any other battery packs may create a risk of injury and fire.
▶When battery pack is not in use, keep it away from other metal
objects, like paper clips, coins, keys, nails, screws or other small
metal objects, that can make a connection from one terminal to
another. Shorting the battery terminals together may cause burns or a
fire.
▶Under abusive conditions, liquid may be ejected from the battery;
avoid contact. If contact accidentally occurs, flush with water. If
liquid contacts eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
▶Do not use a battery pack or tool that is damaged or modified.
Damaged or modified batteries may exhibit unpredictable behaviour
resulting in fire, explosion or risk of injury.
▶Do not expose a battery pack or tool to fire or excessive temperature.
Exposure to fire or temperature above 130° C (265 °F) may cause
explosion.
▶Follow all charging instructions and do not charge the battery pack
or tool outside the temperature range specified in the instructions.
Charging improperly or at temperatures outside the specified range may
damage the battery and increase the risk of fire.
Service
