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.
▶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
▶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.
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.
Printed: 24.09.2018 | Doc-Nr: PUB / 5152424 / 000 / 05

English 3
▶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.
▶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!
Printed: 24.09.2018 | Doc-Nr: PUB / 5152424 / 000 / 05

4 English
▶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 produced 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.
