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.
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 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.
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 information and vibration values
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 electric tool with another. They may be used for a preliminary assessment of exposure. The data given represents the main applications of the electric tool. However, if the electric 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: maintain the tool and the accessories, keep the hands warm, organization of work patterns.
