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.
Printed: 14.12.2018 | Doc-Nr: PUB / 5283568 / 000 / 03

4 English
▶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.
Printed: 14.12.2018 | Doc-Nr: PUB / 5283568 / 000 / 03

English 5
▶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
Personal safety
▶Use the product only when it is in technically faultless condition.
▶Never tamper with or modify the power tool in any way.
▶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.
▶Always grip the side handle at its outermost end. When drilling and
screwdriving, the grip of the power tool may be deflected laterally (the
power tool tends to pivot about its own axis).
▶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 power tool.
▶Wear protective gloves also when changing the accessory tool. Touching
the accessory tool presents a risk of injury (cuts or burns).
Printed: 14.12.2018 | Doc-Nr: PUB / 5283568 / 000 / 03

6 English
▶Wear eye protection. Flying fragments present a risk of injury to the body
and eyes.
▶Before beginning the work, check the hazard classification of the dust
that will be produced. Use an industrial vacuum cleaner with an officially
approved protection classification in compliance with locally applicable
dust protection regulations.
▶Use a dust removal system and suitable vacuum cleaner whenever
possible. Dust from materials, such as paint containing lead, some
wood species, concrete/masonry/stone containing silica, and minerals as
well as metal, may be harmful.
▶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 may cause allergic reactions and/or respiratory
or other diseases to the operator or bystanders. Certain kinds of dust
are classified as carcinogenic such as oak and beech dust, especially
in conjunction with additives for wood conditioning (chromate, wood
preservative). Material containing asbestos may be handled only 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 beginning work, check the working area for concealed electric
cables or gas and water pipes. External metal parts of the power tool may
become live, presenting a risk of electric shock, if you damage an electric
cable accidentally.
Careful handling and use of power tools
▶Switch the power tool off if the accessory tool sticks and stalls. The power
tool may be deflected laterally.
▶Wait until the power tool stops completely before you lay it down.
