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 (cord-less) 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 sur-faces, such as pipes, radiators, ranges and refrigerat-ors. 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 elec-tric shock.
Do not abuse the cord. Never use the cord for carry-ing, 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 suit-able for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is un-avoidable, use a residual current device (RCD) protec-ted 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 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 in-juries.
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 en-ergising power tools that have the switch on invites acci-dents.
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 in-jury.
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 jew-ellery. 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 ex-traction and collection facilities, ensure these are con-nected and properly used. Use of dust collection can re-duce dust-related hazards.
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe in-jury 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 de-signed.
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 re-move the battery pack, if detachable, from the power tool before making any adjustments, changing ac-cessories, 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 main-tained 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 ac-count the working conditions and the work to be per-formed. 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.

Safety Warnings for Drills
Safety instructions for all operations

Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
Use the auxiliary handle(s). Loss of control can cause personal injury.
Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting ac-cessory or fasteners may contact hidden wiring or its own cord. Cutting accessory 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

Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contact-ing the workpiece, resulting in personal injury.
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 contact-ing 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 warnings

Switch the power tool off immediately if the applica-tion tool becomes blocked. Be prepared for high torque reactions which cause kickback. The applica-tion tool becomes blocked when it becomes jammed in the workpiece or when the power tool becomes over-loaded.
Hold the power tool securely. When tightening and loosening screws be prepared for temporarily high torque reactions.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility com-pany 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 dam-age 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.

Products sold in GB only:
Your product is fitted with an 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 au-thorised 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.

When working with the machine, always hold it firmly with both hands and provide for a secure stance. The machine is more securely guided with both hands.

Technical Data

BOSCH-GSB-16-RE-Professional-Impact-Drill-fig-12

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 determined according to EN 62841-2-1.
Typically the A-weighted noise level of the power tool are: 99 dB(A); sound power level 110 dB(A). Uncertainty K = 5 dB.

Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 62841-2-1:

Drilling into metal: ah = 3.0 m/s2, K = 1.5 m/s2
Impact drilling into concrete: ah = 17.5 m/s2, K = 1.5 m/s2
Screwdriving: ah <2.5 m/s2, K = 1.5 m/s2
Thread cutting: ah <2.5 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 com-pare power tools. They may also be used for a preliminary estimation of vibration and noise emissions. The stated vibration level and noise emission value repres-ent the main applications of the power tool. However, if the power tool is used for other applications, with different ap- plication 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. This may significantly reduce vibration and noise emissions over the total working period. Implement additional safety measures to protect the oper-ator 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 (7).

You can swivel the auxiliary handle (7) to any angle for a safe work posture that minimises fatigue. Turn the lower gripping end of the auxiliary handle (7) anti-clockwise and swivel the auxiliary handle (7) into the re-quired position. Afterwards, turn the lower gripping end of the auxiliary handle (7) clockwise to retighten it.

Setting the drilling depth (see figure A)

You can use the depth stop (8) to set the required drilling depth X.
Turn the lower gripping end of the auxiliary handle (7) anti-clockwise and set the depth stop (8).
Pull the depth stop (8) far enough out that the distance between the drill bit tip and the edge of the depth stop (8) corresponds to the required drilling depth X.
Then turn the lower gripping end of the auxiliary handle (7) clockwise to retighten it.
The fluting on the depth stop (8) must face upwards.

Changing the tool

Wear protective gloves when changing tools. The drill chuck may heat up significantly when it is used for long periods.

Keyless chuck (see figure B) The drill spindle is locked when the on/off switch (5) is not pressed. This makes it possible to change the application tool in the drill chuck quickly, conveniently and easily. Open the keyless chuck (1) by turning it in the direction of rotation ➊ until the tool can be inserted. Insert the tool. Firmly tighten the sleeve of the keyless chuck (1) by turning it by hand in the rotational direction ➋ until it stops clicking. This will automatically lock the drill chuck. The lock will disengage again if you turn the sleeve in the op-posite direction to remove the tool.

Keyed chuck (see figure C) Open the keyed chuck (10) by turning it until the tool can be inserted. Insert the tool. Insert the chuck key (9) into the corresponding holes of the keyed chuck (10) and clamp the tool evenly.

Screwdriving tools (see figure D)
You should always use a universal bit holder (12) when using screwdriver bits (11). Only use screwdriver bits that fit the screw head. For screwdriving, make sure the “drilling/impact drilling” se-lector switch (2) is always set to the “drilling” symbol.

Changing the drill chuck

Pull the plug out of the socket before carrying out any work on the power tool.
If your power tool does not have a drill spindle locking mechanism, you must have the drill chuck changed by an authorised after-sales service centre for Bosch power tools.

Removing the Drill Chuck (see figure E)

Remove the auxiliary handle (7).
Insert a steel pin with a diameter of 4 mm and a length of ap-prox. 50 mm into the hole on the spindle collar to lock the drill spindle in place. Clamp a hex key (13) in the keyless chuck (1), leading with the short shaft.
Place the power tool on a firm surface, e.g. a work bench. Hold the power tool in place and loosen the keyless chuck (1) by turning the hex key (13) in the rotational direction ➊. A tightly seated keyless chuck is loosened with a light blow on the long shaft of the hex key (13). Remove the hex key from the keyless chuck and completely unscrew the keyless chuck from the power tool.

Fitting the Drill Chuck (see figure F)

To fit the keyless chuck (1), perform the same steps in re-verse order.
The drill chuck must be tightened using a tight-ening torque of approx. 30–35 Nm.

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 carci-nogenic, 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 ma-terials to be worked.

Avoid dust accumulation at the workplace. Dust can easily ignite.

Operation

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 resid-ual current device (RCD) with a nominal residual current of 30 mA or less.

Setting the rotational direction (see figures G–H)

Only push the rotational direction switch (3) when the power tool is not in use.

The rotational direction switch (3) is used to change the ro-tational direction of the power tool. However, this is not pos-sible while the on/off switch (5) is being pressed.

Clockwise rotation: To drill and drive in screws, slide the rotational direction switch (3) upwards on the left-hand side and downwards on the right-hand side at the same time.
Anti-clockwise rotation: To loosen and unscrew screws and nuts, slide the rotational direction switch (3) downwards on the left-hand side and upwards on the right-hand side at the same time.

Setting the Operating Mode

Drilling and screwdriving
Set the selector switch (2) to the “drilling” sym-bol.
Impact drilling
Set the selector switch (2) to the “impact drilling” symbol.
The selector switch (2) clicks into place and can also be ac-tuated when the motor is running.

Switching on/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.

Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when it is on by pressing in the on/off switch (5) to varying ex-tents.
Applying light pressure to the on/off switch (5) results in a low rotational speed/impact rate. Applying increasing pres-sure to the switch increases the speed/impact rate.

Preselecting the speed/impact rate
You can preselect the required speed/impact rate using the speed preselection thumbwheel (6), even during operation. The required speed/impact rate is dependent on the mater-ial and the work conditions and can be determined by prac-tical trials.

Practical Advice

Pull the plug out of the socket before carrying out any work on the power tool.
Only apply the power tool to the screw/nut when the tool is switched off. Rotating tool inserts can slip off.

After working at a low speed for an extended period, you should operate the power tool at the maximum speed for ap-proximately three minutes without load to cool it down. To drill into tiles, set the selector switch (2) to the “drilling” symbol. After drilling through the tile, set the selector switch to the “impact drilling” symbol and drill with impact. Use carbide drill bits when working with concrete, stone and masonry. When drilling into metal, only use sharpened HSS drills (HSS = high-speed steel) which are in perfect condition. The Bosch accessory range guarantees appropriate quality. Using the drill bit sharpener (accessory), you can effortlessly sharpen twist drill bits with a diameter of 2.5–10 mm. Use a drill stand (accessory) for jobs that require particular precision. The machine vice, which is available as an accessory, en-ables the workpiece to be securely clamped. This prevents the workpiece from turning and any accidents this could cause.

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any work on the power tool.
To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.

In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by Bosch or by an after-sales service centre that is authorised to repair Bosch power tools.
