Safety instructions

General Power Tool Safety Warnings

WARNING

Read all safety warnings, instruc-tions, illustrations and specifications provided with this power tool. Failure to follow all in-structions 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 exten-sion 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 inatten-tion while operating power tools may result in serious per-sonal 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 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 and clothing 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. 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 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 mis-alignment 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. under 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. Noise exposure 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 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 com-plete 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 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 main socket elsewhere.
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 con-trol 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.

Noise/Vibration Information

Noise emission values are determined according to EN IEC 62841-2-6.

Typically, the A-weighted noise level of the power tool is:

Sound pressure level	dB(A)	92	92	92
Sound power level	dB(A)	103	103	103
Uncertainty K	dB	3	3	3

Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN IEC 62841-2-6:

Hammer drilling into concrete:

ah	m/s2	16.5	16.5	15.3
K	m/s2	1.5	1.5	1.5

Chiselling:

ah	m/s2	12.1	12.1	11.5
K	m/s2	1.5	1.5	1.5

The vibration level and noise emission value given in these instructions have been measured by 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 being used should also be taken into account. 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

Do not operate your power tool without the auxiliary handle (14).
Make sure that the auxiliary handle is always tightened. Otherwise, you could lose control of the power tool when working.

Swivelling the auxiliary handle (see Figure A)
You can swivel the auxiliary handle (14) to any angle for a safe work posture that minimises fatigue.

Turn the lower gripping end of the auxiliary handle (14) anticlockwise and swivel the auxiliary handle (14) into the required position. Then turn the lower gripping end of the auxiliary handle (14) 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

Hammer drilling and chiselling require SDS-plus application tools that are inserted into the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plastic as well as for screwdriving, tools without SDS‑plus are used (e.g. cylindrical shank drill bits). For these tools, a keyless chuck or a keyed chuck are required.

Changing the drill chuck

Inserting/removing the keyed chuck

GBH 2-26 RE/GBH 2-26 DRE
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 (20) into a keyed chuck (19). Secure the keyed chuck (19) using the securing screw (18). 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 (5) back and remove the keyed chuck (19).

Removing/inserting the quick-change chuck

GBH 2-26 DFR

Removing the Quick-Change Chuck (see Figure C)

Pull back on the quick-change chuck locking ring (6), hold it in this position and pull the SDS plus quick-change chuck (2) or the keyless quick-change chuck (1) out from the front.
Once the quick-change chuck is removed, protect it from dirt.

Inserting the Quick-Change Chuck (see Figure D)

Before insertion, clean the quick-change chuck and lightly grease the shank.
Wrap your whole hand around the SDS plus quick-change chuck (2) or the keyless quick-change chuck (1). Use a turning motion to push the quick-change chuck into the drill chuck holder (21) until you hear it click into place.
The quick-change chuck is automatically locked. Check that it is locked by pulling on the quick-change chuck.

Changing the Tool
The dust protection cap (4) largely prevents the penetration of drilling dust into the tool holder during operation. When inserting the tool, make sure that the dust protection cap (4) does not become damaged.

Replace a damaged dust protection cap immediately. It is recommended that you use an after-sales service for this.

Changing the tool (SDS Plus)

Inserting SDS plus application tools (see Figure E)
The SDS-plus drill chuck enables you to change the application tool easily and conveniently without needing to use additional tools.

GBH 2-26 DRE: Insert the SDS plus quick-change chuck (2).
Clean and lightly grease the shank of the application tool.
Insert the application tool into the tool holder while turning it until it locks automatically.
Check that it is locked by pulling on 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 does not affect the accuracy of the drill hole, as the drill bit centres itself upon drilling.

Removing SDS-plus application tools (see Figure F)
Push the locking sleeve (5) back and remove the application tool.

Changing the keyed chuck
GBH 2-26 RE/GBH 2-26 DRE

Inserting the Application Tool (see Figure G)

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

Insert a keyed chuck (19).
Open the keyed chuck (19) by turning it until the tool can be inserted. Insert the tool.
Insert the chuck key into the corresponding holes of the keyed chuck (19) and clamp the tool evenly.
GBH 2-26 RE: Set the selector switch (16) to the “drilling” symbol.
GBH 2-26 DRE: Turn the impact/mode selector switch (11) to the “drilling” position.

Removing the application tool
Use the chuck key to turn the sleeve of the keyed chuck (19) anticlockwise until the application tool can be removed.

Changing the keyless quick-change chuck
GBH 2-26 DFR

Inserting the application tool (see Figure H)

Note:

Hold the retaining ring (23) of the keyless quick-change chuck firmly in place. Open the tool holder by turning the front sleeve (22) until the tool can be inserted. Hold the retaining ring (23) in place and firmly tighten the front sleeve (22) by turning it in the direction of the arrow until you hear it click into place.
Check that it is seated securely by pulling on the tool. Note: If the tool holder was unscrewed all the way, a scraping sound may be heard while retightening the tool holder and it may not fully tighten.
In this case, turn the front sleeve (22) in the opposite direction to the arrow by one full turn. This will allow the tool holder to be fully tightened.
Turn the impact/mode selector switch (11) to the “drilling” position.

Removing the application tool (see Figure I)
Hold the retaining ring (23) of the keyless quick-change chuck firmly in place. Open the tool holder by turning the front sleeve (22) in the direction of the arrow until the 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 GDE 16 Plus (accessory) (see Figure J)

For dust extraction, the GDE 16 Plus (accessory) is required.
The dust extractor must be suitable for the material being worked on.
When extracting dry dust or dust that is especially detrimental to health or carcinogenic, use a special dust extractor.

Dust collection cap (accessory) (see figure K)
To collect dust easily without using extraction, a dust collec-tion cap (25) is required.

Dust Extraction with GDE 18V-26 D (accessory)

For dust extraction, the GDE 18V-26 D dust extraction attachment (accessory) is required.
Observe the information on the intended use in the relevant operating manual when using the GDE 18V-26 D.

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

GBH 2-26 RE:
Use the “drilling/hammer drilling” selector switch (16) to select the power tool’s operating mode.

To change the operating mode, press the release button (15) and turn the “drilling/hammer drilling” selector switch (16) 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
- Position for drilling without impact in wood, metal, ceramic and plastic and for screw-driving

GBH 2-26 DRE, GBH 2-26 DFR:
The operating mode of the power tool is selected using the impact/mode selector switch (11).

To change the operating mode, press the release button (10) and turn the impact/mode selector switch (11) 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
Position for drilling without impact in wood, metal, ceramic and plastic and for screwdriving
Vario-Lock position for adjusting the chisel position
The impact/mode selector switch (11) will not engage in this position.
Position for chiselling

Setting the Rotational Direction
The rotational direction switch (7) is used to change the rotational direction of the power tool. However, this is not pos-sible while the on/off switch (9) is being pressed.

Only operate the rotational direction switch (7) when the power tool is not in use.

Always set the rotational direction to the clockwise rotation for hammer drilling, drilling and chiselling.

Rotate clockwise: Turn the rotational direction switch (7) on both sides until it stops in the position.
Rotate anticlockwise: Turn the rotational direction switch (7) on both sides until it stops in the position.

Switching On/Off

To switch on the power tool, press the on/off switch (9).
To lock the on/off switch (9), press and hold it while also pushing the lock-on button (8).
To switch off the power tool, release the on/off switch (9). If the on/off switch (9) is locked, press the switch first and then release it.

Adjusting the Speed/Impact Rate

You can adjust the speed/impact rate of the power tool when it is on by pressing the on/off switch (9) to varying extents.
Applying light pressure to the on/off switch (9) results in a low rotational speed/impact rate. Applying increasing pressure to the switch increases the speed/impact rate.

Changing the chiselling position (Vario-Lock)
You can lock the chisel in 36 different positions, so you can select the optimum working position for each task.

Insert the chisel into the tool holder.
Turn the impact/mode selector switch (11) to the “Vario-Lock” position.
Turn the application tool to the required chisel position.
Turn the impact/mode selector switch (11) to the “chis-elling” position. With this, the tool holder is locked.
Set the rotational direction for chiselling to clockwise.

Practical Advice

Setting the drilling depth (see Figure L)
You can use the depth stop (13) to set the required drilling depth X.

Press the button for depth stop adjustment (12) and insert the depth stop into the auxiliary handle (14).
The fluting on the depth stop (13) must face downwards.
Insert the SDS-plus application tool into the SDS-plus tool holder (3) to the stop. Otherwise, the movability of the SDS-plus drilling tool can lead to incorrect adjustment 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.

Inserting screwdriver bits (see figure M)

Only apply the power tool to the screw/nut when the tool is switched off. Rotating tool inserts can slip off.

A universal holder (26) 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 (5) backward and remove the universal holder (26) from the tool holder.
