Safety Notes
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 seri-ous injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (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 and 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.
Hammer Safety Warnings
- Wear ear protectors. Exposure to noise can cause hearing loss.
- Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting ac- cessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
- 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 explosion. Penetrating a water line causes property damage or may cause an electric shock.
- When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.
- Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Products sold in GB only: Your product is fitted with a BS 1363/A
approved electric plug with internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be cut off and
an appropriate plug fitted in its place by an authorised customer service
agent. The replacement plug should have the same fuse rating as the original
plug.
The severed plug must be disposed of to avoid a possible shock hazard and
should never be inserted into a mains socket elsewhere. Products sold in AUS
and NZ only: Use a residual current device (RCD) with a rated residual current
of 30 mA or less.

The values given are valid for a nominal voltage [U] of 230 V. For differ- ent voltages and models for specific countries, these values can vary. Please observe the article number on the type plate of your machine. The trade names of the individual machines may vary.
Noise/Vibration Information
Measured sound values determined according to 2000/14/EC.
Typically the A-weighted noise levels of the product are:
Sound pressure level 93 dB(A); sound power level 104 dB(A). Uncertainty K =2
dB.
Wear hearing protection! Vibration total values ah (triax vector sum) and
uncertainty K determined according to EN 60745: Chiselling: ah =10 m/s 2 2 , K
=1.5 m/s .
The vibration emission level given in this information sheet has been measured
in accordance with a standardised test given in EN 60745 and may be used to
compare one tool with another. It may be used for a preliminary assessment of
exposure.
The declared vibration emission level represents the main applications of the
tool. However if the tool is used for different applications, with different
accessories or poorly maintained, the vibration emission may differ. This may
significantly increase the exposure level over the total working period. An
estimation of the level of exposure to vibration should also take into account
the times when the tool is switched off or when it is running but not actually
doing the job. This may significantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the operator from the effects
of vibration such as: maintain the tool and the accessories, keep the hands
warm, organisation of work patterns.

Pull out the lock bolt 5 and turn it 180° in clockwise direction. Allow the
lock bolt 5 to latch again. Check the latching by pulling the tool.
Dust/Chip Extraction
- Dusts 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 dusts can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are considered as 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.
Operation
Starting Operation
- Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230 V can also be operated with 220 V.
Switching On and Off
To start the machine, push the On/Off switch 2 to the “I” position. To switch
off the machine, push the On/Off switch 2 to the “0” position.
For low temperatures, the machine reaches the full impact rate only after a
certain time.
This start-up time can be shortened by striking the chisel in the machine
against the floor one time.
Working Advice (see figure G)
- Before any work on the machine itself, pull the mains plug.
While working, hold the power tool with both hands by the handle 1. The handle
1 can move upward and downward around its axis by approx. 30 mm. This has a
damping effect against vibrations.
For the highest possible impact damping, work only with moderate pressure.
Sharpening Chisels
Good results are only achieved with sharp chisels; therefore, sharpen the
chiselling tools in good time. This ensures a long service life of the tools
and good working performance.
Re-sharpening
Sharpen chiselling tools using grinding wheels (e. g. ceramic bonded corundum
wheel) with a steady supply of water. Reference values are shown in the
figure. Take care that no annealing coloration appears on the cutting edges;
this impairs the hardness of the chiselling tools.
For forging, heat the chisel to between 850 and 1050 °C (bright red to
yellow).
For hardening, heat the chisel to approx. 900 °C and quench in oil. Then
anneal in an oven for approx. one hour at 320 °C (annealing colour = light
blue).
Maintenance and Service
Maintenance and Cleaning
- Before any work on the machine itself, pull the mains plug.
- For safe and proper working, always keep the machine and ventilation slots clean.
When the carbon brushes wear below acceptable service tolerances, the machine
will automatically cut out. The machine must be sent to customer service for
maintenance (for address, see the “After-sales Service and Customer
Assistance” section.
If the machine should fail despite the care taken in manufacturing and testing
procedures, repair should be carried out by an after-sales service centre for
