5 OBJ_BUCH book Page 19 Wednesday, December 5, :18 PM English 19 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. 1) Work area safety a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) 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. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. 2) Electrical safety a) 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. b) 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. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) 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 and moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) 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. 3) Personal safety a) 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. b) 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. c) 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. d) 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. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) 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. Bosch Power Tools B57 ( )

6 OBJ_BUCH book Page 20 Wednesday, December 5, :18 PM 20 English g) 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. 4) Power tool use and care a) 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. b) 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. c) 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. d) 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. e) 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. f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g) 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. 5) Battery tool use and care a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. c) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire. d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns. 6) Service a) 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. Machine-specific Safety Warnings Centre Grip Screwdriver Hold power tool by the insulated gripping surfaces, when performing an operation where the cutting tool may run into hidden wiring. Contact with a live wire will make exposed metal parts of the tool live and shock the operator. Do not drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite B57 ( ) Bosch Power Tools

7 OBJ_BUCH book Page 21 Wednesday, December 5, :18 PM English 21 Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. Before any work on the machine (e.g., maintenance, tool change, etc.) as well as during transport and storage, set the rotational direction switch to the centre position. Unintentional actuation of the On/Off switch can lead to injuries. Hold the machine with a firm grip. High reaction torque can briefly occur while driving in and loosening screws. Use only flawless tool bits that are not worn. Defective tool bits can break, for example, and cause injury or damage. When working with an application tool, pay attention that the application tool is firmly seated on the tool holder. When the application tool is not firmly connected with the tool holder, it can come loose again and not be controlled. Be careful when long screws are screwed in. Depending on the type of screw and the tool bit used, there is a danger of slipping. Long screws are often difficult to control and the danger exists that the tool bit may slip off the fastener head and cause injury. Pay attention to the direction of rotation that is set before switching on the power tool. For example, when a screw is to be loosened and the direction of rotation is set so that the screw is tightened, this can lead to a strong torque reaction of the power tool. Do not use this tool as a drill. Tools equipped with shut-off clutches are not designed for drilling applications. The clutch can shut off automatically and without warning. Battery Avoid unintentional switching on. Ensure the On/Off switch is in the off position before inserting battery pack. Carrying the power tool with your finger on the On/Off switch or inserting the battery pack into power tools that have the switch on invites accidents. Do not open the battery. Danger of shortcircuiting. Protect the battery against heat, e.g., also against continuous sun irradiation and fire. There is danger of explosion. Do not short-circuit the battery. There is danger of explosion. Battery leakage may occur under extreme usage or temperature conditions. When a rechargeable battery leaks, avoid contact with the skin or eyes. The battery liquid is caustic and could cause chemical burns to tissues. If liquid comes in contact with skin, wash quickly with soap and water, then with lemon juice or vinegar. If the liquid contacts your eyes, flush them with water for a minimum of 10 minutes and seek medical attention. Functional Description Read all safety warnings and all instructions.

10 OBJ_BUCH book Page 24 Wednesday, December 5, :18 PM 24 English Noise/Vibration Information Measured values determined according to EN Typically the A-weighted sound pressure level of the product is 70 db(a). Uncertainty K=3 db. The noise level when working can exceed 80 db(a). Wear hearing protection! Vibration total values (triax vector sum) determined according to EN 60745: Screwdriving without impact: Vibration emission value a h <2,5 m/s 2, Uncertainty K=1,5 m/s 2. The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 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 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.

12 OBJ_BUCH book Page 26 Wednesday, December 5, :18 PM 26 English Constant voltage regulator (see figure C) Type / / / / / / / / / Note: As an alternative to battery operation, centre grip screwdrivers can also be operated of a constant voltage regulator. The constant voltage regulator and the voltage adapters are not included. The power plug shown can vary from the one on your power tool. Please take care, that the constant voltage regulator is suitable for your country specific electricity network. Apart from the 4EXACT constant voltage regulator and the matching power cable, a voltage adapter with the same rated voltage as your cordless screwdriver is required. The voltage on the constant voltage regulator (LED indicator) must be the same as the voltage of the driver. The constant voltage regulator is suitable exclusively for Bosch industrial battery-operated drivers of the EXACT series, the ANGLE EXACT series, and the BT-EXACT series with a voltage of between 9.6 V and 14.4 V. Otherwise, there exists the risk of fire and explosion. Type / / / / / / These industrial cordless screwdrivers cannot be operated with constant voltage regulator. Connection to the Power Supply Note: Please note that upon delivery neither a battery pack nor a voltage adapter is inserted in the power tool. Never store rechargeable batteries in a battery powered tool. Rechargeable batteries last longer and are easier to recharge when they are stored separately. Remember to fully recharge batteries that have been stored for a longer time before use. Battery Charging Charge the battery with a suitable charging unit before inserting it into the power tool. The exact description of the charging procedure can be found in the operating instructions of the charging unit and the hints in this manual (see Charging Procedure, page 25). The battery is equipped with an NTC temperature sensor that allows charging only in the temperature range between 0 C (+32 F) and 45 C (+113 F). A long service life of the battery is achieved in this manner. With correct usage, the battery can be recharged up to 3000 times. A battery that is new or has not been used for a longer period does not develop its full capacity until after approx. 5 charging/discharging cycles. Batteries should only be recharged when the LED indicator battery condition of the power tool shows red. Battery insertion/removal (see figure D) Move the rotational direction switch 3 to the center position. This action locks the on/off trigger switch 6 in the off position, which prevents the tool from running. Insert a fully charged battery 5 into the handle of the power tools. Insure that the battery is in the correct position and that the locking buttons 4 engage securely into the handle of the power tool. Do not exert any force when inserting/ removing the battery. Batteries with APT contact (Akku Pack Top) are designed in such a manner that they can only be inserted into the power tool or the charger in the correct position. To remove the battery 5, squeeze the locking buttons 4 on both sides and pull the battery downward out of the handle B57 ( ) Bosch Power Tools

13 OBJ_BUCH book Page 27 Wednesday, December 5, :18 PM English 27 Inserting/Removing the Voltage Adapter (see figure E) Type / / / / / / / / / Select the voltage adapter that matches the rated voltage of your power tool. The voltage adapters may be differentiated, depending on the voltage, by the color of the housing of the D-sub connector 16. The housing of the D-sub connector for a voltage of 9.6 V is light blue in color, and that for a voltage of 12 V is red in color. The adapter housing 18 may be mounted in or dismounted from the industrial batteryoperated screwdriver only when the constant voltage regulator is switched off or when the connector 16 is disconnected from the constant voltage regulator. Move the rotational direction switch 3 to the center position. This action locks the on/off trigger switch 6 in the off position, which prevents the tool from running. Insert the adapter housing 18 into the handle of the power tool. Insure that the adapter housing is in the correct position and that the locking buttons 4 engage securely into the handle of the power tool. Subsequently, plug the connector 16 of the voltage adapter 15 that matches your power tool into the connection socket. Screw the connector 16 tightly in the connection socket 15 by tightening the two screws 17 by hand. To remove the voltage adapter, loosen the two screws 17 on the connector 16 of the switched off constant voltage regulator and and pull the connector out of the connection socket 15. Subsequently, squeeze the locking buttons 4 on both sides and pull the adapter housing 18 out of the hande of the power tool. Type / / / / / / These industrial cordless screwdrivers cannot be operated with constant voltage regulator. Changing Application Tools on the Head with Quick-change Chuck (see figure F) When working with an application tool, pay attention that the application tool is firmly seated on the tool holder. When the application tool is not firmly connected with the tool holder, it can come loose again and not be controlled. Inserting Pull the quick-change chuck 19 to the front. Insert the tool 9 into the tool holder 8 and release the quick-change chuck. Use only insertion tools with fitting end pieces (1/4" hexagonal). Do not attempt to insert quick-change type drill bits into this chuck. Centre grip screwdriver equipped with shut-of clutches are not designed for drilling applications. The chlutch can shut-off automatically and without warning. Attempting to restart drilling after shut-off has been reached can cause the power tool to twist out of your hand until the clutch again reaches shutoff. Removing Pull the quick-change chuck 19 to the front. Take the tool 9 out of the tool holder 8 and release the quick-change chuck. Operation Use safety equipment. Always wear eye protection. Safety equipment such as dusk mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. Starting Operation When starting the power tool, you should first select the direction of rotation with the rotational direction switch 3 since the power tool starts only when the rotational direction switch 3 is not in the middle position (switch-on lock).

14 OBJ_BUCH book Page 28 Wednesday, December 5, :18 PM 28 English Reversing the Rotational Direction (see figure G) Right rotation: For driving in screws, push the rotational direction switch 3 left to the stop. Left Rotation: For loosening or unscrewing screws, push the rotational direction switch 3 right to the stop. Actuate the rotational direction switch 3 only when the machine is at a standstill. Switching on the LED Work Area Illumination (see figure H) The work area illumination 20 makes possible the lighting of the screwing position for unfavorable light conditions. The work area illumination 20 is switched on by lightly pressing the on/off switch 6. When the on/off switch is firmly pressed, the power tool is switched on and the work area illumination continues to light. Do not look directly into the work area illumination your sight can be temporarily degraded! Switching On and Off The screwdriver have a shut-off clutch that depends on the torque and can be set in the given range. It responds when the torque that is set is reached. Note: When operating the screwdriver with a voltage adapter, the constant voltage regulator must be put into operation first. To start the machine press the on/off switch 6 to the stop. The machine switches off automatically as soon as the preset torque is reached. When the on/off switch 6 is released prematurely, the preset torque is not reached. Working Advice Before any work on the machine (e.g., maintenance, tool change, etc.) as well as during transport and storage, set the rotational direction switch to the centre position. Unintentional actuation of the On/Off switch can lead to injuries. Apply the power tool to the screw/nut only when it is switched off. Rotating tool inserts can slip off. Setting the Torque (see figures I J) The tightening torque is dependent on the spring pretension of the shut-off clutch. The shut-off clutch responds in right as well as left rotation when the torque setting is reached. For setting the individual tightening torques, use only the adjustment tool 21 provided. Push the slide 10 on the power tool completely back. Insert the adjustment tool 21 into the tool holder 8 and turn it slowly. When a small indentation (adjusting dial 22) is visible in the clutch insert the adjustment tool 21 into the indentation and turn it. Turning in the clockwise direction results in a higher torque, in the counterclockwise direction, a lower torque. Remove the adjustment tool 21. Shut the slide 10 again to protect the clutch against contamination. Note: The required adjustment is dependent on the type of threaded connection and can be best determined by practical trials. Check the trial screwings with a torque wrench. Set the torque only in the specified performance range, otherwise the shut-off clutch will no longer respond. Marking the Torque Setting To identify individually adjusted tightening torques, the marking ring 7 an be replaced with a marking ring of another color. For example, if you are using several EXACT tools set to a torque of 4.5 Nm, you can use the red rings to marque their set values. If you are using more EXACT tools in another part of the assembly process where the torque is set to 7.5 Nm, you can use another marking ring (such as black, blue, green or yellow) to mark the torque range of these units. The different marking rings are only intended as a quick reference for production personnel to easily indentify which tool is set for a given torque range. Press off the marking ring 7 with a thin screwdriver blade, a knife, or similar. Always use the power tool with a marking ring to insure that the housing body is sealed from dust and dirt B57 ( ) Bosch Power Tools

15 OBJ_BUCH book Page 29 Wednesday, December 5, :18 PM English 29 LED Indicators Battery Condition Indicator If the charging of the battery 5 is necessary, the LED indicator 2 blinks green and an acoustical signal sounds. Only 6 8 screwing operations may be possible. When the LED indicator lights up red, the capacity is no longer sufficient for a new screw connection or the power tool has been subject to overload. The power tool can not be switched on anymore. The start lock remains active until the battery pack is removed from the power tool and a charged battery pack is inserted again. When working with a voltage adapter, the red LED indicator 2 indicates an overload. A considerably shortened operating time of the power tool after each charging indicates that the battery must be replaced soon. Dispose of the used battery in accordance with the legal/country-specific regulations. Screwing Fastener Indicator When the preset torque is reached, the shut off coupling responds. The LED indicator 1 lights green. If the preset torque is not reached, the LED indicator 1 lights red and an acoustical signal sounds. The screwing fastener must be performed again. Repeat Protection When the shut-off coupling responds for a screwing fastener, the motor shuts off. Switching on again is possible only after a 0,7 second delay. In this manner, an unintentional re-tightening of an already seated screw is avoided. Maintenance and Service Maintenance and Cleaning Before any work on the machine (e.g., maintenance, tool change, etc.) as well as during transport and storage, set the rotational direction switch to the centre position. Unintentional actuation of the On/Off switch can lead to injuries. For safe and proper working, always keep the machine and ventilation slots clean. When the battery is no longer operative, please refer to an authorised after-sales service agent for Bosch power tools. If the machine should fail despite the care taken in manufacturing and testing procedures, repair should be carried out by an after-sales service centre for Bosch power tools.
