Failure to follow the warnings and instructions may result in electric shock, fire and/or seri- ous 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 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 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 cord away from heat, oil, sharp edges and 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 suitable for outdoor use reduces the risk of electric shock. If operating a power tool in a damp location is unavoid- able, use a residual current device (RCD) protected 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 inattention while op- erating power tools may result in serious personal injury. 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 inju- ries. WARNING OBJ_BUCH-1051-002.book Page 12 Monday, December 17, 2012 2:13 PMEnglish | 13 Bosch Power Tools 1 609 92A 00N | (17.12.12) 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 ro- tating 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 jewel- lery. Keep your hair, clothing and gloves 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. 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 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 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. 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. Check for misalignment or bind- ing 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 and tool bits etc. in ac- cordance 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. Battery tool use and care Recharge only with the charger specified by the manu- facturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another bat- tery pack. Use power tools only with specifically designated bat- tery packs. Use of any other battery packs may create a risk of injury and fire. When battery pack is not in use, keep it away from oth- er 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. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally oc- curs, flush with water. If liquid contacts eyes, addition- ally seek medical help. Liquid ejected from the battery may cause irritation or burns. Service Have your power tool serviced by a qualified repair per- son using only identical replacement parts. This will en- sure that the safety of the power tool is maintained. Safety Warnings for Drills and Screwdriver Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory or fastener may contact hidden wiring. Cutting accesso- ry and fasteners contacting a “live” wire may make ex- posed metal parts of the power tool “live” and could give the operator an electric shock. Use appropriate 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. Switch off the power tool immediately when the tool in- sert jams. Be prepared for high reaction torque that can cause kickback. The tool insert jams when: — the power tool is subject to overload or — it becomes wedged in the workpiece. Hold the machine with a firm grip. High reaction torque can briefly occur while driving in and loosening screws. Secure the workpiece. A workpiece clamped with clamp- ing devices or in a vice is held more secure than by hand. Keep your workplace clean. Blends of materials are par- ticularly dangerous. Dust from light alloys can burn or ex- plode. 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. Do not open the battery. Danger of short-circuiting. Protect the battery against heat, e. g., against continuous intense sunlight, fire, water, and moisture. Danger of explosion. In case of damage and improper use of the battery, va- pours may be emitted. Ventilate the area and seek medical help in case of complaints. The vapours can irri- tate the respiratory system. OBJ_BUCH-1051-002.book Page 13 Monday, December 17, 2012 2:13 PM14 | English 1 609 92A 00N | (17.12.12) Bosch Power Tools When the battery is defective, liquid can escape and come into contact with adjacent components. Check any parts concerned. Clean such parts or replace them, if required. Use the battery only in conjunction with your Bosch power tool. This measure alone protects the battery against dangerous overload. Use only original Bosch batteries with the voltage list- ed on the nameplate of your power tool. When using oth- er batteries, e.g. imitations, reconditioned batteries or other brands, there is danger of injury as well as property damage through exploding batteries.

The vibration emission level given in this information 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 expo- sure. The declared vibration emission level represents the main ap- plications 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 in- crease 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 sig- nificantly reduce the exposure level over the total working pe- riod. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep hands warm, organise work patterns.

Assembly Battery Charging Use only the battery chargers listed on the accessories page. Only these battery chargers are matched to the lith- ium ion battery of your power tool. Note: The battery is supplied partially charged. To ensure full capacity of the battery, completely charge the battery in the battery charger before using your power tool for the first time. The Lithium-Ion battery can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery. The Lithium-Ion battery is protected against deep discharging by the “Electronic Cell Protection (ECP)”. When the battery is empty, the machine is switched off by means of a protective circuit: The inserted tool no longer rotates. Do not continue to press the On/Off switch after the machine has been automatically switched off. The bat- tery can be damaged. The battery is equipped with a NTC temperature control which allows charging only within a temperature range of be- tween 0 °C and 45 °C. A long battery service life is achieved in this manner. Observe the notes for disposal. Removing the battery The battery 7 is equipped with two locking levels that should prevent the battery from falling out when pushing the battery unlocking button 8 unintentionally. As long as the battery is inserted in the power tool, it is held in position by means of a spring. To remove the battery 7, press the unlocking button 8 and pull out the battery toward the front. Do not exert any force. Changing the Tool (see figure A) Before any work on the machine (e. g., maintenance, tool change, etc.) as well as during transport and stor- age, set the rotational direction switch to the centre position. Unintentional actuation of the On/Off switch can lead to injuries. Inserting Pull the locking sleeve 2 forward, push the insert tool to the stop into the tool holder 1 and release the locking sleeve 2 to lock the insert tool. Use only screwdriver bits with ball catch 12 (DIN 3126- E6.3). Other screwdriver bits 14 can be used with a universal bit holder with ball catch 13. Removing Pull the locking sleeve 2 forward and remove the insert tool. Operation Operation Method – Impact Driving The tool holder 1 with the tool is driven by an electric motor via a gear and impact mechanism. The working procedure is divided into two phases: Screwing in and tightening (impact mechanism in action). The impact mechanism is activated as soon as the screwed connection runs tight and thus load is put on the motor. In this instance, the impact mechanism converts the power of the motor to steady rotary impacts. When loosening screws or nuts, the process is reversed.

Dr. Egbert Schneider Senior Vice President Engineering Helmut Heinzelmann Head of Product Certification PT/ETM9 OBJ_BUCH-1051-002.book Page 15 Monday, December 17, 2012 2:13 PM16 | English 1 609 92A 00N | (17.12.12) Bosch Power Tools Starting Operation Inserting the battery Use only original Bosch lithium ion batteries with the voltage listed on the nameplate of your power tool. Us- ing other batteries can lead to injuries and pose a fire haz- ard. Set the rotational direction switch 9 to the centre position to protect the power tool against accidental starting. Insert the charged battery 7 from the front into the base of the power tool until the battery is securely locked. Reversing the rotational direction (see figure B) The rotational direction switch 9 is used to reverse the rota- tional direction of the machine. However, this is not possible with the On/Off switch 10 actuated. Right rotation: For driving in screws, tightening nuts and for drilling, push the rotational direction switch 9 leftwards through to the stop. Left rotation: For loosening and unscrewing screws, nuts and drill bits, push the rotational direction switch 9 right- wards through to the stop. Setting the operating mode (see figure C) The machine’s operating mode is selected with the “drilling/ screwdriving” selector switch 4. Note: Change the operating mode only when the machine is switched off! Otherwise, the machine can be damaged. To change the operating mode, push the “drilling/screwdriv- ing” selector switch 4 to the desired position. When the “drilling/screwdriving” selector switch 4 cannot be pushed through to the stop, slightly press the On/Off switch 10 and release it again before pushing the “drilling/screwdriv- ing” selector switch 4 to the desired position. Always push the “drilling/screwdriving” selector switch 4 through to the stop. Operating the machine with the “drilling/screwdriving” selector switch 4 not complete- ly pushed through can result in damage to the power tool. Switching On and Off To start the machine, press the On/Off switch 10 and keep it pressed. The power light 3 lights up when the On/Off switch 10 is slightly or completely pressed, and allows the work area to be illuminated when lighting conditions are insufficient. To switch off the machine, release the On/Off switch 10. To save energy, only switch the power tool on when using it. Adjusting the Speed The speed of the switched on power tool can be variably ad- justed, depending on how far the On/Off switch 10 is pressed. Light pressure on the On/Off switch 10 results in a low rota- tional speed. Further pressure on the switch results in an in- crease in speed. Working Advice Apply the power tool to the screw/nut only when it is switched off. Rotating tool inserts can slip off. When drilling, do not apply excessive feed pressure with the machine. Excessive feed pressure can damage the drill bit tip, impair the working performance, and re- duce the power tool’s service life. The torque depends on the impact duration. The maximum achieved torque results from the sum of all individual torques achieved through impact. The maximum torque is achieved after an impact duration of 6–10 seconds. After this dura- tion, the tightening torque is increased only minimally. The impact duration is to be determined for each required tightening torque. The actually achieved tightening torque is always to be checked with a torque wrench. Screw Applications with Hard, Spring-loaded or Soft Seat When in a test, the achieved torques in an impact series are measured and transferred into a diagram, resulting in the curve of a torque characteristic. The height of the curve corre- sponds with the maximum reachable torque, and the steep- ness indicates the duration in which this is achieved. A torque gradient depends on the following factors: – Strength properties of the screws/nuts – Type of backing (washer, disc spring, seal) – Strength properties of the material being screwed/bolted together – Lubrication conditions at the screw/bolt connection The following application cases result accordingly: –A hard seat is given for metal-to-metal screw applications with the use of washers. After a relatively short impact du- ration, the maximum torque is reached (steep characteris- tic curve). Unnecessary long impact duration only causes damage to the machine. –A spring-loaded seat is given for metal-to-metal screw ap- plications, however with the use of spring washers, disc springs, studs or screws/nuts with conical seat as well as when using extensions. –A soft seat is given for screw applications, e. g., metal on wood or when using lead washers or fibre washers as back- ing. For a spring-loaded seat as well as for a soft seat, the maxi- mum tightening torque is lower than for a hard seat. Also, a clearly longer impact duration is required. Position for impact driving Position for low-speed drilling with large drilling diameters in wood, metal, ceramics and plastic Position for high-speed drilling with small drilling diameters in wood, metal, ceramics and plastic OBJ_BUCH-1051-002.book Page 16 Monday, December 17, 2012 2:13 PMEnglish | 17 Bosch Power Tools 1 609 92A 00N | (17.12.12) Reference Values for Maximum Screw/Bolt Tightening Torques Calculated from the tensional cross-section; utilization of the yield point 90 % (with friction coefficient μ total = 0.12). As a control measure, always check the tightening torque with a torque wrench. Tips Before screwing larger, longer screws into hard materials, it is advisable to predrill a pilot hole with the core diameter of the thread to approx.

of the screw length. Belt Clip With the belt clip 6, the machine can be hung onto a belt. The user has both hands free and the machine is always at hand. Recommendations for Optimal Handling of the Battery Protect the battery against moisture and water. Store the battery only within a temperature range between 0 °C and 50 °C. As an example, do not leave the battery in the car in summer. Occasionally clean the venting slots of the battery using a soft, clean and dry brush. A significantly reduced working period after charging indi- cates that the battery is used and must be replaced. Observe the notes for disposal. Maintenance and Service Maintenance and Cleaning Before any work on the machine (e. g., maintenance, tool change, etc.) as well as during transport and stor- age, 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. Replacing the Carbon Brushes (see figure D) Check the length of the carbon brushes approx. every 2 –3 months and replace the carbon brushes if required. Never replace only a single carbon brush! Note: Use only carbon brushes supplied by Bosch and intend- ed specifically for your product. – Unscrew the caps 16 using a suitable screwdriver. – Replace the spring-loaded carbon brushes 15 and screw the caps back on again. If the machine should fail despite the care taken in manufac- turing and testing procedures, repair should be carried out by an after-sales service centre for Bosch power tools.
