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 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 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 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 or fasteners may contact hidden wiring or its own cord. Cutting accessories or fasteners 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.

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 authorized 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 main socket elsewhere.
Do not touch any application tools or adjacent housing components shortly after the 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.

Technical Data

BOSCH-GBH-2-23-S-Professional-Lus-Hammer-Drill-FIG-3

The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.

Assembly

Pull the plug out of the socket before carrying out any work on the power tool.
Auxiliary handle
Do not operate your power tool without the auxiliary handle (11).
Make sure that the auxiliary handle is always tightened. Otherwise, you could lose control of the power tool when working.

Swiveling the auxiliary handle (see Figure A)

You can swivel the auxiliary handle (11) to any angle for a safe work posture that minimizes fatigue.
Turn the lower gripping end of the auxiliary handle (11) anticlockwise and swivel the auxiliary handle (11) into the required position.
Then turn the lower gripping end of the auxiliary handle (11) clockwise to retighten it.
Make sure that the retaining strap of the auxiliary handle slots into the corresponding groove of the housing.
Selecting drill chucks and tools
For hammer drilling and chiseling ( only with accessory MV 200), you will need SDS plus tools, which insert into the SDS plus drill chuck.
For drilling without impact in wood, metal, ceramic, and plastic as well as for screw driving, tools without SDS plus are used (e.g. cylindrical shank drill bits).
For these tools, a keyless chuck or a keyed chuck is required.
Changing the drill chuck
Inserting/removing the keyed chuck
You must use a suitable drill chuck (keyed or keyless chuck, accessories) to work with tools that do not have SDS-plus (e.g. cylindrical shank drill bits).

Fitting the keyed chuck (see Figure B)

Screw the SDS-plus shank (15) into a keyed chuck (14).
Secure the keyed chuck (14) using the securing screw (13). Note that the securing screw has a left-hand thread.
Inserting the keyed chuck (see Figure B)
Clean and lightly grease the insertion end of the shank.
Insert the keyed chuck with the adapter shank into the tool holder with a turning motion until it automatically locks.
Check that it is locked by pulling the keyed chuck. Removing the keyed chuck
Push the locking sleeve (3) back and remove the keyed chuck (14).
Changing the Tool
The dust protection cap (2) largely prevents the penetration of drilling dust into the tool holder during operation.
When inserting the tool, make sure that the dust protection cap (2) does not become damaged.
Replace a damaged dust protection cap immediately.
It is recommended that you have use an after-sales service for this.

Changing the tool (SDS Plus)

Inserting SDS-plus application tools (see Figure C)
The SDS-plus drill chuck enables you to change the application tool easily and conveniently without needing to use additional tools.
Clean and lightly grease the insertion end of the application tool.
Insert the application tool into the tool holder while turning it until it locks automatically.
Check the latching by pulling the tool. As a requirement of the system, the SDS-plus application tool can move freely.
This causes a certain radial run-out at no-load, which has no effect on the accuracy of the drill hole, as the drill bit centers itself upon drilling.
Removing SDS-plus application tools (see Figure D)
Push the locking sleeve (3) back and remove the application tool.

Changing the Keyed Chuck

Inserting the application tool
Note: Application tools that do not have SDS plus must not be used for hammer drilling or chiseling. Tools without SDS plus and their drill chucks are damaged by hammer drilling or chiseling.

Insert a keyed chuck (14).
Open the keyed chuck (14) by turning it until the tool can be inserted. Insert the tool.
Insert the chuck key into the corresponding holes of the keyed chuck (14) and clamp the tool evenly.
Set the selector switch (8) to the “drilling” symbol. Removing the application tool
Use the chuck key to turn the sleeve of the keyed chuck (14) anticlockwise until the application tool can be removed.

Dust/Chip Extraction
The dust from materials such as lead paint, some types of wood, minerals, and metal can be harmful to human health. Touching or breathing in this dust can trigger allergic reactions and/or cause respiratory illnesses in the user or in people in the near vicinity. Certain dust, such as oak or beech dust, are classified as carcinogenic, especially in conjunction with wood treatment additives (chromate, wood preservative). Materials containing asbestos may only be machined by specialists. Use a dust extraction system that is suitable for the material wherever possible.

Provide good ventilation at the workplace.
It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can easily ignite.

Dust extraction with the dust extraction attachment (accessory) Fitting the dust extraction attachment (see Figure E) For dust extraction, the dust extraction attachment (accessory) is required. When drilling, the dust extraction attachment retracts so that the attachment head is always close to the surface of the drill hole.

Press the button for depth stop adjustment (9) and remove the depth stop (10). Press the button (9) again and insert the dust extraction attachment into the auxiliary handle (11) from the front.
Connect an extraction hose (diameter 19 mm, accessory) to the suction opening (16) of the dust extraction attachment. The dust extractor must be suitable for the material being worked.
When extracting dust that is dry, especially detrimental to health, or carcinogenic, use a special dust extractor. Setting the drilling depth on the dust extraction attachment (see Figure F)
You can also set the required drilling depth X when the dust extraction attachment is fitted.
Push the SDS-plus application tool into the SDS-plus tool holder (1) as far as it will go. Otherwise, the movability of the SDS-plus drilling tool can lead to incorrect adjustment of the drilling depth.
Loosen the wing bolt (20) on the dust extraction attachment.
Without switching it on, press the power tool firmly against the surface you wish to drill. The SDS-plus application tool must be touching the surface.

Position the guide tube (21) of the dust extraction attachment in its holder such that the head of the dust extraction attachment rests on the surface to be drilled. Do not slide the guide tube (21) further than necessary over the telescopic tube (19), so that as much as possible of the scale remains visible on the telescopic tube (19).

Retighten the wing bolt (20). Loosen the clamping screw (17) on the depth stop of the dust extraction attachment.
Slide the depth stop (18) onto the telescopic tube (19) so that the distance X shown in the illustration matches your required drilling depth.
Tighten the clamping screw (17) in this position.
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.

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
Use the “drilling/hammer drilling” selector switch (8) to select the power tool’s operating mode.
To change the operating mode, press the release button (7) and turn the “drilling/hammer drilling” selector switch (8) until it clicks into the required position.
Note : Only change the operating mode when the power tool is switched off. Otherwise, the power tool may become damaged.
Position for hammer drilling into concrete or stone and for chiseling (chisel only with accessory MV 200)
Position for drilling without impact in wood, metal, ceramic, and plastic and for screw-driving Setting the Rotational Direction GBH 2-23 RE
The rotational direction switch (4) is used to change the rotational direction of the power tool. However, this is not possible while the on/off switch (6) is being pressed.
Only operate the rotational direction switch (4) when the power tool is not in use.
Always set the rotational direction to the clockwise rotation for hammer drilling, drilling, and chiseling.
Rotate clockwise: Turn the rotational direction switch (4) on both sides until it stops in the position.
Rotate anticlockwise: Turn the rotational direction switch (4) on both sides until it stops in position. Switching On/Off
To switch on the power tool, press the on/off switch (6).
To lock the on/off switch (6), press and hold it while also pushing the lock-on button (5).
To switch off the power tool, release the on/off switch (6). If the on/off switch (6) is locked, press the switch first and then release it. Adjusting the Speed/Impact Rate GBH 2-23 E/GBH 2-23 RE
You can adjust the speed/impact rate of the power tool when it is on by pressing in the on/off switch (6) to varying extents.
Applying light pressure to the on/off switch (6) results in a low rotational speed/impact rate. Applying increasing pressure to the switch increases the speed/impact rate.
Practical Advice Setting the drilling depth (see Figure G)
You can use the depth stop (10) to set the required drilling depth X.
Press the button for depth stop adjustment (9) and insert the depth stops into the auxiliary handle (11). The fluting on the depth stop (10) must face downwards.
Insert the SDS-plus application tool into the SDS-plus tool holder (1) to the stop. Otherwise, the movability of the SDS-plus drilling tool can lead to incorrect adjustments of the drilling depth.
Pull the depth stop far enough out that the distance between the drill bit tip and the edge of the depth stop corresponds to the required drilling depth X.
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.
Chiseling For chiseling, you will need an SDS Plus chisel MV 200 attachment (accessory), which inserts into the SDS Plus tool holder (1).
The dust extraction system must not be mounted when chiseling. Inserting screwdriver bits (see Figure H)
Only apply the power tool to the screw/nut when the tool is switched off. Rotating tool inserts can slip off. A universal holder (22) with an SDS-plus shank (accessory) is required to work with screwdriver bits.
Clean and lightly grease the insertion end of the shank.

Insert the universal holder into the tool holder while turning it until it locks automatically.

Check that it is locked by pulling the universal holder.
Insert a screwdriver bit in the universal holder. Only use screwdriver bits that fit the screw head.
To remove the universal holder, slide the locking sleeve (3) backward and remove the universal holder (22) from the tool holder.
