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 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 exten-sion 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 jewelry. 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 ac-cordance 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 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.
Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.
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.

Technical Data

The values given are valid for a nominal voltage [U] of 230 V. For different voltages and models for specific countries, these values can vary.

Noise/Vibration Information
Sound emission values determined according to EN 60745-2-6.
Typically the A-weighted noise levels of the product are: Sound pressure level 93 dB(A); Sound power level 104 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:
Hammer drilling into concrete: ah= 10.5 m/s2, K= 4.4 m/s2 Chiselling: ah = 7.5 m/s2, K= 1.5 m/s2
The vibration level given in this information sheet has been measured in accordance with a standardized 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 insertion tools or is 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.

Assembly

Before any work on the machine itself, pull the mains plug.

Auxiliary Handle

Operate your machine only with the auxiliary handle 10.

The auxiliary handle 10 can be set to any position for a secure and low- fatigue working posture.

Turn the bottom part of the auxiliary handle 10 in counterclockwise direction and swivel the auxiliary handle 10 to the desired position. Then retighten the bottom part of the auxiliary handle 10 by turning in clockwise direction.

Changing the Tool
With the SDS-max tool holder, simpler and easier tool chang-ing is possible without additional aids.
The dust protection cap 1 largely prevents the penetration of dust into the tool holder during operation. When inserting the tool, pay attention that the dust protection cap 1 is not dam-aged.

Hammer-1

A damaged dust protection cap should be changed immediately. We recommend having this carried out by an after-sales service.

Inserting (see figure A)

Clean and lightly grease the shank end of the tool.
Insert the tool in a twisting manner into the tool holder until it latches itself.
Check the latching by pulling the tool.

Removing (see figure B)

Push back the locking sleeve 2 and remove the 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

Starting Operation

Observe correct mains voltage! The voltage of the pow-er 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.

Setting the operating mode
The operating mode of the power tool is selected using the mode selector switch 3.
Note: Change the operating mode only when the machine is switched off! Otherwise, the machine can be damaged.

Turn the mode selector switch 3 to the desired position.

In the “chiselling” position, the impact rate preselected with the thumbwheel 7 is automatically increased when switching on; this causes the power tool to operate with increased capacity when chiselling.

Switching On/Off in Drilling Mode
To save energy, only switch the power tool on when using it.

To start the machine, press the On/Off switch 5 and keep it pressed.
To switch off the machine, release the On/Off switch 5.

Switching On/Off in Chiselling Mode
To save energy, only switch the power tool on when using it.

To start the machine, press the On/Off switch 5 at the top (I) until it locks.
To switch off the machine, press the On/Off switch 5 at the bottom (0) and release it.

For low temperatures, the power tool reaches the full hammer/impact capacity only after a certain time.

Setting the Speed/Impact Rate
The electronic control enables stepless speed and impact preselection in accordance with the material to be worked.
The constant electronic control keeps the preselected speed and impact rate nearly constant between no-load and load conditions.
When plugging the plug into the socket outlet or after a power failure, the constant electronic control automatically sets the highest speed and impact rate. This ensures working at optimum performance despite too low preadjustment of the thumbwheel 7.

Select the impact rate with the thumbwheel 7 according to the material.
The data in the following table are recommended values.

Overload Clutch

If the tool insert becomes caught or jammed, the drive to the drill spindle is interrupted. Because of the forces that occur, always hold the power tool firmly with both hands and provide for a secure stance.
If the power tool jams, switch the machine off and loosen the tool insert. When switching the machine on with the drilling tool jammed, high reaction torques can occur.

Changing the Chiselling Position (Vario-Lock)
The chisel can be locked in 12 positions. In this manner, the optimum working position can be set for each application.

Insert the chisel into the tool holder.
Turn the mode selector switch 3 to the position “Vario-Lock” (see “Setting the operating mode”, page 13).
Turn the tool holder to the desired chiselling position.
Turn the mode selector switch 3 to the position “Chisel-ling”. With this, the tool holder is locked.

For chiselling, the mode selector switch 3 must always be set to the position “Chiselling”.

Working Advice

Before any work on the machine itself, pull the mains plug.

Vibration Damper

The integrated vibration damper reduces occurring vibrations.

The soft grip handle increases the safety against slipping off and thus provides for a better grip and handling of the power tool.

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.
A damaged dust protection cap should be changed immediately. We recommend having this carried out by an after-sales service.

If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in order to avoid a safety hazard.

Service Indicator 8
When the carbon brushes are worn out, the machine switches itself off. This is indicated approx. 8 hours beforehand by the lighting or blinking of the service indicator 8. The machine must then be sent to an after-sales service agent. Addresses are listed in the Section “After-sales Service and Application Service”.

Stand-by Indicator 9
When the mains plug is plugged in and mains voltage is given, the stand-by indicator 9 must be lit. When the machine can not be switched on despite lit stand-by indicator 9, it must be sent to an after-sales service agent; for addresses, see section “After-sales Service and Application Service”, page 14.
