General Power Tool Safety Warnings
WARNING
Read all safety warnings. instruc-tions, illustrations and specifica-tions 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 i nat ten Lion while operating power tools may result in serious personal 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 injuries.
► 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 accidents.
► 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.
► 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 tum 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 dean. 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.
Battery tool use and care
► Recharge only with the charger specified by the manu-facturer. A charger that is suitable for one type of bat-tery pack may create a risk of fire when used with another battery pack.
► Use power tools only with specificaNy 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 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.
► Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally oc-curs, flush with water. If liquid contacts eyes, addi-tionally seek medical help. Liquid ejected from the bat-tery may cause irritation or burns.
► Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire. explosion or risk of injury.
► Do not expose a battery pack or tool to fire or excess-ive temperature. Exposure to fire or temperature above 130°C may cause explosion.
► Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire. 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.
► Never service damaged battery packs. Service of bat-tery packs should only be performed by the manufacturer or authorized service providers.
Safety information for drills and screwdrivers
Safety instructions for all operations
GSB
► Wear ear protectors when impact driffing. Exposure to noise can cause hearing loss.
GSB / GSR
► Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting ac-cessory or fasteners may contact hidden wiring. Cut-ting 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
► Hold the power tool securely. When tightening and loosening screws be prepared for temporarily high torque reactions.
► Secure the workpiece. A workpiece damped with clamping devices or in a vice is held more secure than by hand.
► Use suitable detectors to determine if there are hid-den supply lines or contact the local utility company for assistance. Contact with electric cables can cause fire and electric shock. Damaging gas lines can lead to ex-plosion. Breaking water pipes causes property damage.
► 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.
► In case of damage and improper use of the battery, va-pours may be emitted. The battery can set alight or ex-plode. Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.
► Do not open the battery. There is a risk of short-circuit-ing.
► The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn. smoke, explode or overheat.
► Only use the battery with products from the manufac-turer. This is the only way in which you can protect the battery against dangerous overload.
Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short- circuiting.
► 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.

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

► Remove the battery from the power tool before carry-ing out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.

Charging the Battery

► Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your power tool.
Note: The battery is supplied partially charged. To ensure full battery capacity, fully charge the battery in the 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 process does not damage the battery.
The lithium-ion battery is protected against deep discharge by the “Electronic Cell Protection (ECP)”. When the battery is discharged, the power tool is switched off by means of a protective circuit: The application tool no longer rotates. Follow the instructions on correct disposal.
Removing the Battery
The battery (7) is equipped with two locking levels to pre-vent the battery from falling out when pushing the battery re-lease button (8) unintentionally. As long as the battery is in-serted in the power tool, it is held in position by means of a spring.
To remove the battery (7), press the release button (8) and pull the battery out of the power tool. Do not use force to do this.
Battery Charge Indicator
The green LEDs on the battery charge indicator (14) indic-ate the state of charge of the battery (7). For safety reasons. it is only possible to check the state of charge when the power tool has been stopped.
Press the battery charge indicator button (15) to show the state of charge. This is also possible when the battery is removed.
If no LED lights up after pressing the battery charge indicator button (15). the battery is defective and must be replaced.

Battery Model ProCORE18V… (see figure D2)

Changing the tool (see figure A)
► Remove the battery from the power tool before carry-ing out work on the power tool (e.g. maintenance, changing tool. etc.). The battery should also be re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch. The drill spindle is locked when the on/off switch (11) is not pressed. This makes it possible to change the application tool in the drill chuck quickly. conveniently and easily.
Open the keyless chuck (2) by turning it in the direction of rotation 1 until the tool can be inserted. Insert the tool. Firmly tighten the keyless chuck (2) by turning it by hand in the direction of rotation 2. This will automatically lock the dril thick.
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 ad-ditives (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 materials to be worked.
► Avoid dust accumulation at the workplace. Dust can easily ignite.

Operation

Starting Operation
Inserting the battery
Note:
The use of batteries unsuitable for your power tool can lead to malfunctions or damage to the power tool. Push the charged battery (7) into the base of the power tool from the front until the battery is securely locked.
Setting the rotational direction (see figure B)
The rotational direction switch (10) is used to change the ro-tational direction of the power tool. However, this is not pos-sible while the on/off switch (11) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-tational direction switch (10) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts. press the rotational direction switch (10) through to the right stop.
Setting the Operating Mode
Drilling
GSR
Set the torque presetting ring (3) to the ‘drifting’ symbol.
GSB
Set the mode selector switch (4) to the “drilling’ symbol.
Screwdriving
GSR
Set the torque presetting ring (3) to the re-quired torque.
GSB
Set the mode selector switch (4) to the “screw-driving” symbol.
Impact drilling (GSB)
Set the mode selector switch (4) to the 9mpact drilling’ symbol.
Switching on/off
To start the power tool, press and hold the on/off switch (11). The LED (9) lights up when the on/off switch (11) is lightly or fully pressed, meaning that the work area is illuminated in poor lighting conditions.
To switch off the power tool, release the on/off switch (11).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by pressing in the on/off switch (11) to varying extents.
A light pressure on the on/off switch (11) results in a low ro-tational speed. Increased pressure on the switch causes an increase in speed.
Preselecting torque (applies to screwdriving mode)
The torque presetting ring (3) can be used to pre-select the required torque in 20 stages. Once the set torque has been reached. the application tool will be stopped.
Mechanical gear selection
► Only operate the gear selector (5) when the power tool is not in use. First gear: Low speed range: for working with a large drilling diameter or for screwdriving.
Second gear:
High speed range: for working with a small drilling diameter.
► Always push the gear selector switch as far as it wiN go. Otherwise. the power tool may become damaged.
Temperature-dependent overload protection
When used as intended. the power tool cannot be over-loaded. In the event of overloading or the temperature rising/falling outside the permitted operating temperature range. the speed will be reduced. The power tool will not run at full speed again until the permitted operating temperature has been reached.
Fully automatic spindle lock (Auto-Lock)
The drill spindle. and therefore the tool holder. are locked when the on/off switch (11) is not pressed.
This allows screws to be driven in even when the battery is discharged and enables the power tool to be used as a screwdriver.
Practical advice
► Only apply the power tool to the screw when the tool is switched off. Rotating application tools can slip off. Before screwing larger, longer screws into hard materials, it is advisable to pre-drill a pilot hole with the core diameter of the thread to approx. 2/3 of the screw length. An auxiliary tool can be used to remove the screwdriver bit or universal bit holder.

Maintenance and Service

Maintenance and Cleaning
► Remove the battery from the power tool before carry-ing out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch. ► To ensure safe and efficient operation, always keep the power tool and the ventilation slots dean.
