Safety Notes 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 battery-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. Distrac- tions 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, 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 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 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 residual cur- rent device (RCD) protected supply. Use of an RCD 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 influ- ence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious person- al injury. b) Use personal protective equipment. Al- ways wear eye protection. Protective equipment such as dust 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 fin- ger on the switch or energising power tools that have the switch on invites acci- dents. d) Remove any adjusting key or wrench be- fore turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal inju- ry. WARNING OBJ_BUCH-824-002.book Page 16 Tuesday, March 2, 2010 9:44 AMEnglish | 17 Bosch Power Tools 2 609 932 762 | (2.3.10) e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unex- pected situations. f) Dress properly. Do not wear loose cloth- ing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. g) If devices are provided for the connec- tion of dust extraction and collection fa- cilities, 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 was de- signed. 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 re- paired. 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 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 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 mis- alignment or binding of moving parts, breakage of parts and any other condi- tion that may affect the power tool’s op- eration. 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 and tool bits etc. in accordance with these in- structions, taking into account the work- ing 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.

a) Have your power tool serviced by a qual- ified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. Safety Warnings for Drills f Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss. f Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal in- jury. f Hold power tool by insulated gripping sur- faces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock. f Use appropriate 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 explosion. Penetrating a water line causes property damage or may cause an electric shock. f When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands. OBJ_BUCH-824-002.book Page 17 Tuesday, March 2, 2010 9:44 AM18 | English 2 609 932 762 | (2.3.10) Bosch Power Tools f Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. 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 machine 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 Never use the machine with a damaged ca- ble. Do not touch the damaged cable and pull the mains plug when the cable is dam- aged while working. Damaged cables in- crease the risk of an electric shock. 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 fit- ted in its place by an authorised customer serv- ice 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 in- serted into a mains socket elsewhere. Products sold in AUS and NZ only: Use a resid- ual current device (RCD) with a rated residual current of 30 mA or less. Functional Description Read all safety warnings and all instructions.

Typically the A-weighted noise levels of the product are: Sound pressure level 95 dB(A); Sound power level 106 dB(A). Uncertainty K=3dB. Wear hearing protection! Vibration total values (triax vector sum) deter- mined according to EN 60745: Drilling into metal: Vibration emission value

Impact drilling into concrete: Vibration emission value a

Screwdriving without impact: Vibration emis- sion value a

The vibration emission level given in this infor- mation sheet has been measured in accordance with a standardised test given in EN 60745 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 repre- sents 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 signifi- cantly increase the exposure level over the total working period. An estimation of the level of exposure to vibra- tion should also take into account the times when the tool is switched off or when it is run- ning but not actually doing the job. This may sig- nificantly reduce the exposure level over the to- tal 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. Declaration of Conformity We declare under our sole responsibility that the product described under “Technical Data” is in conformity with the following standards or standardization documents: EN 60745 accord- ing to the provisions of the directives 2004/108/EC, 2006/42/EC.

OBJ_BUCH-824-002.book Page 20 Tuesday, March 2, 2010 9:44 AMEnglish | 21 Bosch Power Tools 2 609 932 762 | (2.3.10) Assembly f Before any work on the machine itself, pull the mains plug. Auxiliary Handle (see figure A) f Operate your machine only with the auxilia- ry handle 8. The auxiliary handle 8 can be set in 12 positions to achieve a safe and low-fatigue working stance. Turn the bottom part of the auxiliary handle 8 in rotation direction n and push the auxiliary han- dle 8 forward until you can pivot it to the desired position. Then pull the auxiliary handle 8 back again and tighten it by turning the bottom part of the auxiliary handle in rotation direction o. Adjusting the Drilling Depth (see figure A) The required drilling depth X can be set with the depth stop 9. Turn the bottom part of the auxiliary handle 8 in anticlockwise direction and insert the depth stop 9. 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. Afterwards, tighten the bottom part of the auxil- iary handle 8 again by turning in clockwise direc- tion. The knurled surface of the depth stop 9 must face upward. Changing the Tool f Wear protective gloves when changing the tool. The drill chuck can become very hot during longer work periods. Keyless Chuck (GSB 19-2 RE) (see figure B) The drill spindle is locked when the On/Off switch 6 is not pressed. This makes quick, con- venient 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 action (“click”) is no longer heard. This automat- ically locks the chuck. The locking is released again to remove the tool when the collar is turned in the opposite direc- tion. Keyless Chuck (GSB 780) (see figure C) Hold the rear sleeve 12 of the keyless chuck 1 tight and turn the front sleeve 11 in rotation di- rection n, until the tool can be inserted. Insert the tool. Hold the rear sleeve 12 of the keyless chuck 1 tight and firmly turn the front sleeve 11 in rota- tion direction o by hand until the locking action is no longer heard. This automatically locks the drill chuck. The locking is released again to remove the tool when the front sleeve 11 is turned in the oppo- site direction. Key Type Drill Chuck (see figure D) Open the key type drill chuck 14 by turning until the tool can be inserted. Insert the tool. Insert the chuck key 13 into the corresponding holes of the key type drill chuck 14 and clamp the tool uniformly. Screwdriver Tools (see figure E) When working with screwdriver bits 15, a uni- versal bit holder 16 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 machine itself, pull the mains plug. Removing the Drill Chuck (see figure F) Disassemble the auxiliary handle and set the gear selector 7 to the centre 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. OBJ_BUCH-824-002.book Page 21 Tuesday, March 2, 2010 9:44 AM22 | English 2 609 932 762 | (2.3.10) Bosch Power Tools Clamp the short end of an Allen key 17 into the keyless chuck 1. Place the machine on a stable surface (e. g. a workbench). Hold the machine firmly and loos- en the keyless chuck 1 by turning the Allen key 17 in rotation direction n. Loosen a tight-seated keyless chuck by giving the long end of the Allen key 17 a light blow. Remove the Allen key from the keyless chuck and completely unscrew the keyless chuck. For machines with key chuck, disassembly is carried out analogous as described above. For machines with keyless chuck, an open-end spanner (size 19 mm) can be applied to the drill chuck instead of an Allen key. Mounting the Drill Chuck (see figure G) The keyless chuck/key type drill chuck is mount- ed 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. 50–55 Nm. Dust/Chip Extraction f Dusts from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touch- ing or breathing-in the dusts can cause aller- gic reactions and/or lead to respiratory infec- tions of the user or bystanders. Certain dusts, such as oak or beech dust, are considered as carcinogenic, 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 work- ing place. – It is recommended to wear a P2 filter- class respirator. Observe the relevant regulations in your country for the materials to be worked. Operation Starting Operation f Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230 V can also be operated with 220 V. Reversing the Rotational Direction (see figure H) f Actuate the rotational direction switch 3 only when the machine is at a standstill. The rotational direction switch 3 is used to re- verse the rotational direction of the machine. However, this is not possible with the On/Off switch 6 actuated. Right rotation: For drilling and driving in screws, push the rotational direction switch 3 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 3 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. Impact Drilling Set the selector switch 2 to the “Im- pact drilling” symbol. The selector switch 2 engages noticeably and can also be actuated with the machine running. Gear Selection, Mechanical f The gear selector 7 can be actuated on ma- chines running at low speed. However, this should not be done when the machine is stopped, at full load or running at maximum speed. OBJ_BUCH-824-002.book Page 22 Tuesday, March 2, 2010 9:44 AMEnglish | 23 Bosch Power Tools 2 609 932 762 | (2.3.10) Two speed ranges can be preselected with the gear selector 7. Gear I: Low speed range; for working with large drilling diameter or for driv- ing in screws. Gear II: High speed range; for working with small drilling diameter. If the gear selector 7 cannot be fully engaged, lightly rotate the drive spindle with the drill bit by twisting the drill chuck. Switching On and Off To start the machine, press the On/Off switch 6 and keep it pressed. To lock the pressed On/Off switch 6, press the lock-on button 4. To switch off the machine, release the On/Off switch 6 or when it is locked with the lock-on button 4, briefly press the On/Off switch 6 and then release it. Safety Clutch To limit dangerous reaction torque, the machine is equipped with a safety clutch (anti-rotation). f If the tool insert becomes caught or jammed, the drive to the drill spindle is in- terrupted. Because of the forces that occur, always hold the power tool firmly with both hands and provide for a secure stance. f If the power tool jams, switch the machine off and loosen the tool insert. When switch- ing the machine on with the drilling tool jammed, high reaction torques can occur. Adjusting the Speed/Impact Frequency The speed/impact rate of the switched on pow- er tool can be variably adjusted, depending on how far the On/Off switch 6 is pressed. Light pressure on the On/Off switch 6 results in low speed/impact rate. Further pressure on the switch increases the speed/impact rate. Preselecting the Speed/Impact Frequency With the thumbwheel for speed preselection 5, the required speed/impact frequency can be preselected even during operation. The required speed/impact frequency depends on the material and the working conditions, and can be determined through practical testing. Working Advice 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 until 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 sharpened with the drill bit sharpener (see ac- cessories). Maintenance and Service Maintenance and Cleaning f Before any work on the machine itself, pull the mains plug. f For safe and proper working, always keep the machine and ventilation slots clean. 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. In all correspondence and spare parts order, please always include the 10-digit article number given on the type plate of the machine.
