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.
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.

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 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.
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 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.
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 Hammer safety warnings
▶Wear ear protectors. Exposure to noise can cause hearing loss.
▶Use auxiliary handles, if supplied with the tool. Loss of control can cause personal injury.
▶Hold power tool by insulated gripping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live" and could give the operator an electric shock.
2.3 Additional safety instructions for rotary hammer
Personal safety
▶Use the product only when it is in technically faultless condition.
▶Never tamper with or modify the power tool in any way.
▶Use the auxiliary grips supplied with the tool. Loss of control can cause personal injury.
▶Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking
through. Parts breaking away could fall out and / or fall down causing injury to other persons.
▶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 work in which the accessory
tool might come into contact with concealed wiring. If the accessory tool comes into contact with a live
wire, metal parts of the power tool can also become live, resulting in an electric shock.
Printed: 02.02.2017 | Doc-Nr: PUB / 5150803 / 000 / 03

4 English
▶Avoid touching rotating parts – risk of injury!
▶Wear suitable protective glasses, a hard hat, ear defenders, protective gloves and light respiratory
protection while using the power 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 can be harmful to health.
▶Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust can cause allergic reactions and/or
respiratory or other diseases to the operator or bystanders. Certain kinds of dust such as oakwood
and beechwood dust are classified as carcinogenic, especially in conjunction with additives for wood
conditioning (chromate, wood preservative). Only specialists are permitted to handle material containing
asbestos.
▶Take breaks 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 beginning work, check the working area for concealed electric cables, gas pipes and water
pipes. External metal parts of the power tool can become live, presenting a risk of electric shock, if you
accidentally damage an electric cable.
Power tool use and care
▶Immediately switch off the power tool if the accessory tool jams. The power tool might twist off-line.
▶Wait until the power tool stops completely before you lay it down.

4.2 Noise and vibration values in accordance with EN 60745
The sound pressure and vibration values given in these instructions were measured in accordance with a
standardized test and can be used to compare one power tool with another. They can also 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 can vary. This can
significantly increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times when the tool is switched off, or
when it is running but not actually being used for a job. This can 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.
