General Power Tool Safety Warnings Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in elec- tric 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 bat- tery-operated (cordless) power tool.

a) Keep work area clean and well lit. Clut- tered 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 the risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, radia- tors, 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 or moving parts. Dam- aged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for out- door use. Use of a cord suitable for out- door use reduces the risk of electric shock. f) If operating a power tool in a damp loca- tion is unavoidable, use a ground fault cir- cuit interrupter (GFCI) or an earth leak- age circuit breaker (ELCB). Use of a GFCI or an ELCB reduces the risk of electric shock.

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. Al- ways wear eye protection. Protective equipment such as dusk mask, non-skid safety shoes, hard hat or hearing protec- tion 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 bat- tery 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. d) Remove any adjusting key or wrench be- fore turning the power tool on. A wrench or a key that is left attached to a rotating part of the power tool may result in per- sonal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables bet- ter control of the power tool in unexpected situations. f) Dress properly. Do not wear loose cloth- ing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. WARNING OBJ_BUCH-129-002.book Page 6 Tuesday, October 23, 2007 2:57 PMEnglish | 7 Bosch Power Tools 1 609 929 M40 | (23.10.07) g) If devices are provided for the connection of dust extraction and collection facili- ties, 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 cor- rect power tool for your application. The correct power tool will do the job better and safer at the rate for which it is de- signed. b) Do not use the power tool if the switch does not turn it on or 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 adjust- ments, changing accessories, or storing power tools. Such preventive safety mea- sures 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 unfa- miliar with the power tool or these in- structions to operate the power tool. Power tools are dangerous in the hands of untrained users. e) Maintain power tools. Check for misalign- ment or binding of moving parts, break- age 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. Prop- erly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g) Use the power tool, accessories, tool bits etc. in accordance with these instruc- tions, taking into account the working conditions and the work to be performed. Use of the power tool for operations differ- ent from those intended could result in a hazardous situation.

• a) Have your power tool serviced by a quali- fied repair person using only identical re- placement parts. This will ensure that the safety of the power tool is maintained. Power Tool-specific Safety Warnings f Wear hearing protection when using impact drills. The influence of noise can lead to loss of hearing. f Use the auxiliary handle supplied with the power tool. Loss of control over the power tool can cause personal injury. f 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 explo- sion. Penetrating a water line causes property damage. f Switch off the power tool immediately when the tool insert jams. Be prepared for high re- action torque that can cause kickback. The tool insert jams when: – the power tool is subject to overload or – it becomes wedged in the workpiece. f Hold the power tool only by the insulated gripping surfaces when performing an oper- ation where the cutting tool may contact hid- den wiring or its own power cord. Contact with a “live” wire will also make exposed met- al parts of the power tool “live” and shock the operator. f When working with the power tool, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands. f Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. f Do not work materials containing asbestos. Asbestos is considered carcinogenic. OBJ_BUCH-129-002.book Page 7 Tuesday, October 23, 2007 2:57 PM1 609 929 M40 | (23.10.07) Bosch Power Tools 8 | English f Take protective measures when dust can de- velop during working that is harmful to one’s health, combustible or explosive. Example: Some dusts are regarded as carcinogenic. Wear a dust mask and work with dust/chip ex- traction when connectable. f Keep your workplace clean. Blends of mate- rials are particularly dangerous. Dust from light alloys can burn or explode. f Always wait until the power tool 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. f Do not use the power tool with a damaged cord. Do not touch the damaged cord and pull the plug from the outlet when the cord is damaged while working. Damaged cords increase the risk of an electric shock.

OBJ_BUCH-129-002.book Page 9 Tuesday, October 23, 2007 2:57 PM1 609 929 M40 | (23.10.07) Bosch Power Tools 10 | English Assembly Auxiliary Handle (see figure A) f Operate your power tool only with the auxil- iary handle 12. The auxiliary handle 12 can be set to any position for a secure and low-fatigue working positure. Turn the bottom part of the auxiliary handle 12 in counterclockwise direction and swivel the auxil- iary handle 12 to the desired position. Then re- tighten the bottom part of the auxiliary handle 12 by turning in clockwise direction. Adjusting the Drilling Depth (see figure A) The required drilling depth X can be set with the depth stop 13. Press the button for the depth stop adjustment 11 and insert the depth stop into the auxiliary handle 12. Pull out the depth stop until the distance be- tween the tip of the drill bit and the tip of the depth stop correspond with the desired drilling depth X. The knurled surface of the depth stop 13 must face upward. Changing the Tool f Before any work on the power tool itself, pull the mains plug. Keyless Chuck (see figure B) The drill spindle is locked when the On/Off switch 7 is not pressed. This makes quick, conve- nient and easy changing of the tool in the drill chuck possible. Open the keyless chuck 1 by turning in rotation direction n until the tool can be inserted. Insert the tool. Firmly tighten the collar of the keyless chuck 1 by hand in rotation direction o until the locking ac- tion (“click”) is no longer heard. This automati- cally locks the chuck. The locking is released again to remove the tool when the collar is turned in the opposite direc- tion. Key-type Drill Chuck (see figure C) f Wear protective gloves when changing the tool. The drill chuck can become very hot dur- ing longer work periods. Open the key-type drill chuck 15 by turning until the tool can be inserted. Insert the tool. Insert the chuck key 14 into the corresponding holes of the key-type drill chuck 15 and clamp the tool uniformly. Screwdriver Tools (see figure D) When working with screwdriver bits 16, a univer- sal bit holder 17 should always be used. Use only screwdriver bits that fit the screw head. For driving screws, always position the “Drill- ing/Impact Drilling” selector switch 2 to the “Drilling” symbol. Replacing the Drill Chuck f Before any work on the power tool itself, pull the mains plug. f For power tools without spindle lock, the drill chuck must be replaced by an autho- rized after-sales service agent for Bosch power tools. Removing the Drill Chuck (see figure E) Disassemble the auxiliary handle and set the gear selector 10 to the center position between the 1st and 2nd gear. Insert a steel pin with a diameter of Ø 4 mm and approx. 50 mm of length into the drill hole on the spindle neck in order to lock the drill spindle. Clamp the short end of a hex key 18 into the key- less chuck 1. Place the machine on a stable surface (e. g. a workbench). Hold the machine firmly and loosen the keyless chuck 1 by turning the hex key 18 in rotation direction n. Loosen a tight-seated key- less chuck by giving the long end of the hex key 18 a light blow. Remove the hex key from the key- less chuck and completely unscrew the keyless chuck. OBJ_BUCH-129-002.book Page 10 Tuesday, October 23, 2007 2:57 PMEnglish | 11 Bosch Power Tools 1 609 929 M40 | (23.10.07) Mounting the Drill Chuck (see figure F) The keyless chuck is mounted in reverse order. f Remove the steel pin from the drill hole on the spindle neck after mounting is complet- ed. The drill chuck must be tightened with a tightening torque of approx. 35–40 Nm. Operation Starting Operation f Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the type plate of the power tool. Reversing the Rotational Direction (see figures G–H) (GSB 20-2 RE/ GSB 20-2 RCE/GSB 20-2 RET) f Actuate the rotational direction switch 5 only when the power tool is at a standstill. The rotational direction switch 5 is used to re- verse the rotational direction of the machine. However, this is not possible with the On/Off switch 7 actuated. Right rotation: For drilling and driving in screws, push the rotational direction switch 5 downward on the left side and at the same time upward on the right side. Left rotation: For loosening and unscrewing screws and nuts, push the rotational direction switch 5 upward on the left side and at the same time downward on the right side. Setting the Operating Mode Drilling and Screwdriving Set the selector switch 2 to the “Drill- ing” symbol. Hammer Drilling Set the selector switch 2 to the “Ham- mer drilling” symbol. The selector switch 2 engages noticeably and can also be actuated with the machine running. Gear Selection, Mechanical f The gear selector 10 can be actuated at standstill or when the machine is running. However, this should not be done while op- erating at full load or maximum speed. Two speed ranges can be preselected with the gear selection lever 10. Gear I: Low speed range; for working with large drilling diameter or for driving in screws. Gear II: High speed range; for working with small drilling diameter. If the gear selection lever 10 cannot be fully en- gaged, lightly rotate the drill bit by twisting the drill chuck. Switching On and Off To start the power tool, press the On/Off switch 7 and keep it pressed. To lock the pressed On/Off switch 7, press the lock-on button 9. To switch off the power tool, release the On/Off switch 7 or when it is locked with the lock-on but- ton 9, briefly press the On/Off switch 7 and then release it. Overload Clutch To limit dangerous reaction torque, the machine is equipped with a safe- ty clutch (anti-rotation). f 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 switch- ing the power tool on with the drilling tool jammed, high reaction torques can occur. OBJ_BUCH-129-002.book Page 11 Tuesday, October 23, 2007 2:57 PM1 609 929 M40 | (23.10.07) Bosch Power Tools 12 | English Adjusting the Speed/Impact Frequency (GSB 20-2 RE/GSB 20-2 RCE/GSB 20-2 RET) The speed/impact rate of the switched on power tool can be variably adjusted, depending on how far the On/Off switch 7 is pressed. Light pressure on the On/Off switch 7 results in low speed/impact rate. Further pressure on the switch increases the speed/impact rate. Preselecting the Speed/Impact Frequency (GSB 20-2 RE) With the dial control for speed preselection 8, the required speed/impact frequency can be pre- selected even during operation. The required speed/impact frequency depends on the material and the working conditions, and can be determined through practical testing. Electronic Speed Preselection (GSB 20-2 RCE/GSB 20-2 RET) With the speed dial for electronic speed prese- lection 3, the required speed/impact frequency can be selected even if the machine is running. The required speed/impact frequency depends on the material and the working conditions, and can be determined through practical testing. Constant Electronic Control (GSB 20-2 RCE/GSB 20-2 RET) The constant electronic control keeps the prese- lected speed and impact rate nearly constant be- tween no-load and load conditions. Electronic Torque Limitation/Speed Preselec- tion (Torque Control) (GSB 20-2 RET) Drilling with speed preselection: Set the selector switch 4 to the “Drilling” symbol. The required speed can be selected with the speed dial 3; it can also be adjusted during operation. Screwdriving with torque limitation: Set the selector switch 4 to the “Screwdriving” symbol. The effective torque at the drill spindle can be vari- able adjusted with the dial control 3 during operation: I=low torque, III=high torque. The maximum speed is automatically adapted to the adjusted torque. If the preselected torque is reached during screwdriving, the machine switches off; the drill- ing tool no longer rotates. If the load on the ma- chine is then removed with the On/Off switch 7 still pressed, the drilling tool continues to run only at very low speed for safety reasons. After briefly releasing the On/Off switch 7, the next screw can be driven in with the same torque. For screwdriving without torque lim- itation, turn the speed dial 3 to the right stop. This setting is required, when the torque in position III is not sufficient. Working Instructions f Apply the power tool to the screw/nut only when it is switched off. Rotating tool inserts can slip off. Tips After longer periods of working at low speed, al- low the machine to cool down by running it for ap- prox. 3 minutes at maximum speed with no load. For drilling in tiles, set the selector switch 2 to the “Drilling” symbol. Do not switch over to the symbol “Impact Drilling” or work with impact un- til after drilling through the tile. Use carbide tipped drill bits when working in concrete, masonry and brick wall. For drilling in metal, use only perfectly sharp- ened HSS drill bits (HSS = High Speed Steel). The appropriate quality is guaranteed by the Bosch accessories program. Twist drills from 2.5–10 mm can easily be sharp- ened with the drill bit sharpener (see accesso- ries). OBJ_BUCH-129-002.book Page 12 Tuesday, October 23, 2007 2:57 PMEnglish | 13 Bosch Power Tools 1 609 929 M40 | (23.10.07) Soft Grip The gripping surface (soft grip) 6 reduces the danger of slipping and thereby improves the grip on the machine and the handling. At the same time, the rubber coating achieves a vibration-reducing effect. Maintenance and Service Maintenance and Cleaning f Before any work on the power tool itself, pull the mains plug. f For safe and proper working, always keep the power tool and the ventilation slots clean. If the power tool should fail despite the care tak- en in manufacturing and testing procedures, re- pair should be carried out by an after-sales ser- vice center for Bosch power tools. In all correspondence and spare parts orders, please always include the 10-digit article number given on the type plate of the power tool.
