2 Safety
2.1 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.
Work area safety
▶Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
Printed: 30.05.2017 | Doc-Nr: PUB / 5152424 / 000 / 04

English 3
▶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.
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 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 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.
Printed: 30.05.2017 | Doc-Nr: PUB / 5152424 / 000 / 04

▶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.
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 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.
▶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.
▶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. 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.
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.
Service
▶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.
2.2 Additional safety precautions for screwdrivers
Personal safety
▶Only use the product if it is in perfect working order.
▶Never tamper with or modify the tool in any way.
▶Use the auxiliary grip supplied with the tool. Loss of control can cause
personal injury.
▶Always hold the power tool with both hands on the grips provided. Keep
the grips clean and dry.
▶Hold the power tool by the insulated gripping surfaces when performing an
operation where the accessory tool may come into contact with concealed
wiring. If the accessory tool comes into contact with a live wire, metal
parts of the power tool may also become live, causing the operator to
receive an electric shock.
▶Avoid touching rotating parts – risk of injury!
▶Wear suitable protective glasses, a hard hat, ear protection, protective
gloves and light respiratory protection while using the tool.
▶Wear protective gloves also when changing the accessory tool. Touching
the accessory tool presents a risk of injury (cuts or burns).
▶Wear eye protection. Flying fragments present a risk of injury to the body
and eyes.
▶Before starting work, check the hazard class of the dust that will be pro-
duced when working. Use an industrial vacuum cleaner with an officially
approved protection class in compliance with the locally applicable dust
protection regulations. Dust from materials such as lead-based paint,
certain types of wood and concrete/masonry/stone containing quartz,
minerals or metal may be harmful to health.
▶Make sure that the working area is well ventilated and, where necessary,
wear a respirator appropriate for the type of dust generated. Contact with
or inhalation of dust may cause allergic reactions and/or respiratory
or other diseases to the operator or bystanders. Certain kinds of
dust, such as oak and beech dust, are classified as carcinogenic,
especially in conjunction with additives for treating wood (chromate,
wood preservative). Materials containing asbestos may only be handled
by specialists.

▶Take breaks between working and do physical exercises to improve the
blood circulation in your fingers. Exposure to vibration during long periods
of work can lead to disorders of the blood vessels and nervous system in
the fingers, hands and wrists.
Electrical safety
▶Before starting work, check the working area for concealed electric cables
or gas and water pipes. If you damage an electric cable accidentally,
external metal parts of the power tool may become live and present a risk
of electric shock.
Careful handling and use of power tools
▶Switch the power tool off immediately if the accessory tool jams. The
power tool may go off course and veer to the side.
▶Wait until the power tool has come to a complete stop before setting it
down.

4.1 Noise information and vibration values in accordance with
EN 60745
The sound pressure and vibration values given in these instructions have
been measured in accordance with a standardized test and may be used to
compare one power tool with another. They may be used for a preliminary
assessment of exposure.
The data given represents the main applications of the power tool. However,
if the power tool is used for different applications, with different accessory
tools or is poorly maintained, the data may vary. This may significantly
increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times
when the power tool is switched off, or when it is running but not actually
being used for a job. This may significantly reduce exposure over the total
working period.
Identify additional safety measures to protect the operator from the effects
of noise and/or vibration, for example: Maintaining the power tool and
accessory tools, keeping the hands warm, organization of work patterns.
