Safety instructions

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 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 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 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 dust masks, non-skid safety shoes, hard hats, 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 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.
• Use auxiliary handle(s), 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.
• 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.

Products sold in GB only:
Your product is fitted with a BS 1363/A approved electric plug with an 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 the main socket elsewhere. u 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.

Technical Data

The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
Noise/Vibration Information
Noise emission values were determined according to EN 60745-2-6.
Typically, the A-weighted noise level of the power tool is Sound pressure level 96 dB(A); sound power level 107 dB(A). Uncertainty K=3 dB.
Wear hearing protection
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-6: Chiselling: ah = 14 m/s2, K = 1,5 m/s2 The vibration level and noise emission value given in these instructions have been measured in accordance with a standardised measuring procedure and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period.
To estimate vibration and noise emissions accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account.
Bosch Power Tools
This may significantly reduce vibration and noise emissions over the total working period. Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organising workflows correctly.
Assembly

• Pull the plug out of the socket before carrying out any work on the power tool.

Auxiliary handle (see figure A)

• Do not operate your power tool without the auxiliary handle (6).

You can swivel the auxiliary handle (6) to any angle for a safe work posture that minimises fatigue. ­ Loosen the knurled nut (8), rotate the auxiliary handle (6) around the axis of the tool to the required position and retighten the knurled nut (8). The auxiliary handle (6) can be refitted in a different position. ­ To do this, completely unscrew the knurled nut (8) and then pull the hexagon bolt upwards and out. ­ Pull off the auxiliary handle (6) to the side and rotate the remaining clamping element by 180°. ­ Fit the auxiliary handle (6) by following the steps in reverse order.
Changing the Tool
With the SDS-max tool holder, you can change the application tool simply and easily without additional aids. The dust protection cap (1) largely prevents the penetration of drilling dust into the tool holder during operation. When inserting the tool, make sure that the dust protection cap (1) does not become damaged.
Replace a damaged dust protection cap immediately.
It is recommended that you have used an after-sales service for this.
Inserting the application tool (see figure B) ­ Clean and lightly grease the shank of the application tool. ­ Push the locking sleeve (2) back and insert the applica- on the tool by turning it into the tool holder. Release the locking sleeve (2) to lock the application tool. ­ Check the latching by pulling the tool.
Removing the application tool (see figure C) ­
Push the locking sleeve (2) back and remove the applica-tion tool.
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.
Operation
Pull the plug out of the socket before carrying out any work on the power tool.
Starting Operation

• 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.
• 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.

Switching On and Off ­
To start the power tool, press and hold the on/off switch (5). ­ Press the lock-on button (4) to lock the on/off switch (5) in this position. ­ To switch off the power tool, release the on/off switch (5); or, if the switch is locked with the lock-on button (4), briefly press the on/off switch (5) and then release it. At low temperatures, the power tool will take a certain amount of time to reach its full impact performance. You can shorten this warm-up time by tapping the power tool’s inserted application tool on the ground once.

Changing the Chiselling Position (Vario-Lock)

You can lock the chisel in 12 different positions, allowing you to select the optimum working position for each task.Turn the chisel adjustment switch (3) to the Changing the Chiselling Position (Vario-Lock) position.
Insert the chisel into the tool holder and turn the chisel to the required position.
Turn the chisel adjustment switch (3) to the Chiselling position and turn the chisel until it audibly clicks into place.

Working Advice
Sharpening Chisels
Only sharp chiselling tools will produce good results, therefore sharpen your chiselling tools in good time before use.
This will ensure a long service life for the tools and good work results.
Re-sharpening
Grind chiselling tools against sanding discs, e.g. aluminium oxide, under a steady stream of water. Make sure that the cutting edges show no annealing colours; this will impair the hardness of the chiselling 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 colour: pale blue).
