Safety instructions
General Power Tool Safety Warnings
WARNING Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below 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 the 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 that 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 the 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 the 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. The 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. The 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 a 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 a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing 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 jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry 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. The use of dust collection can reduce dust-related hazards.
- Do not let familiarity gained from the frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
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 remove the battery pack, if detachable, 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 and accessories. 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 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.
- Keep handles and grasping surfaces dry, clean, and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
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.
Hammer Safety Warnings
Safety instructions for all operations
- Wear ear protectors. Exposure to noise can cause hearing loss.
- Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
- Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessories contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Safety instructions when using long drill bits with rotary hammers
- Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
- Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend, causing breakage or loss of control, resulting in personal injury.
Additional safety information
- Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to an explosion. Penetrating a water line causes property damage or may cause an electric shock.
- Always wait until the power tool has come to a complete stop before placing it down. The application tool can jam and cause you to lose control of the power tool.
- Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more securely than by hand.
- Do not touch any application tools or adjacent housing components shortly after operation. These can become very hot during operation and cause burns.
- The application tool may jam during drilling. Make sure you have a stable footing and hold the power tool firmly with both hands. Otherwise, you could lose control of the power tool.
- Take care when carrying out demolition work using the chisel. Falling fragments of the demolition material could injure you or any bystanders.
- Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.

Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some wood types,
minerals, and metal can be harmful to one’s health. Touching or breathing in
the dust can cause allergic reactions and/or lead to respiratory infections of
the user or bystanders. Certain dust, such as oak or beech dust, is considered
carcinogenic, especially in connection with wood-treatment additives
(chromate, wood preservative). Materials containing asbestos may only be
worked by specialists.
- Provide for good ventilation of the working place.
- It is recommended to wear a P2 filter-class respirator. Observe the relevant regulations in your country for the materials to be worked.
- Avoid dust accumulation at the workplace. Dust can easily ignite.
Operation
- Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less.
Start-up
- Pay attention to the mains voltage! The voltage of the power source must match the voltage specified on the rating plate of the power tool. Power tools marked with 230 V can also be operated with 220 V.
Setting the Operating Mode
- The operating mode of the power tool is selected using the mode selector switch (3).
- To change the operating mode, turn the mode selector switch (3) to the required position.
Note: Only change the operating mode when the power tool is switched off. Otherwise, the power tool may become damaged.

- Vario-Lock position for changing the chiselling position
- Position for chiselling
Switching On/Off
- To start the power tool, press the on/off switch (4) and keep it pressed.
- To switch off, release the on/off switch (4). For low temperatures, the power tool reaches the full hammer/ impact capacity only after a certain time.
Adjusting the Speed/Impact Rate
The electronic control enables continuous speed and impact rate preselection
for material-specific adjustments.
- Select the impact rate with the thumbwheel (6) according to the material.
The information in the table below describes the recommended values.
Changing the chiseling position (Vario-Lock)
You can lock the chisel in 12 different positions, allowing you to select the
optimum working position for each task.
- Insert the chisel into the tool holder.
- Turn the mode selector switch (3) to the “drilling” position.
- Turn the application tool to the required chisel position.
- Turn the mode selector switch (3) to the “chiseling” position. With this, the tool holder is locked.
Practical Advice
Overload clutch
- If the application tool jams or snags, the power transmission to the drill spindle will be interrupted. Always hold the power tool firmly with both hands to withstand the forces this may create and adopt a position with stable footing.
- Switch the power tool off immediately and remove the application tool if the power tool becomes blocked. Switching on when the drilling tool is blocked may cause high torque reactions.
Sharpening Chisels
Only sharp chiseling tools will produce good results, therefore sharpen your
chiseling tools in good time before use. This will ensure a long service life
for the tools and good work results.
Re-sharpening
Grind chiseling tools against sanding discs, e.g. aluminum oxide, under a
steady stream of water. Make sure that the cutting edges show no annealing
colors; this will impair the hardness of the chiseling tools. To forge a
chisel, heat it to 850–1050 °C (pale red to yellow). To harden a chisel, heat
it to approx. 900 °C and quench in oil. Then, leave it in an oven for approx.
one hour at 320 °C (annealing color: pale blue).
