Safety instructions

General Power Tool Safety Warnings
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 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 or moving parts. Damaged or entangled cords increase the risk of electric shock. u When operating a power tool outdoors, use an extension 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) 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 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 energising 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 jewellery. 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 connected and properly used. Use of dust collection can reduce 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 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 re-move the battery pack, if detachable, 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 and accessories. 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. 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 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 manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. Use power tools only with specifically designated battery 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 occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery 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 excessive 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.

Technical Data

 

Permitted ambient temperature

Limited performance at temperatures < 0 °C

Noise/Vibration Information

Noise emission values determined according to EN 62841-2-2.

Typically, the A-weighted noise level of the power tool is: Sound pressure level 87 dB(A); sound power level 98 dB(A). Uncertainty K = 3 dB.

Wear hearing protection

Total vibration values ah (triax vector sum) and uncertainty K determined according to EN 62841-2-2: Impact tightening of fasteners of the maximum capacity of the tool: ah = 10.5 m/s2, K = 1.5 m/s2. The vibration level and noise emission value given in these instructions have been measured in accordance with a standardized measuring procedure detailed in EN 62841 and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions. The given vibration level and noise emission value represent 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 operator from the effects of vibration, such as servicing the power tool and application tools, keeping the 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 re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.

Battery Charging

Use only the chargers listed on the accessories page. Only these chargers are matched to the lithium-ion battery of your power tool. 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. To remove the battery (8), press the release button (7) and pull the battery downwards out of the power tool. Do not use force to do this.

Removing the battery

To remove the battery (8), press the release button (7) and pull the battery downwards out of the power tool. Do not use force to do this.

Changing the Tool
Remove the battery from the power tool before carrying 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. Regularly clean the power tool’s air vents. The motor’s fan can draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. GDR 12 V-110:
Inserting the application tool. Pull the locking sleeve (2) forward, guide the application tool (1) into the tool holder up to the stop and release the locking sleeve (2) to lock the application tool. Screwdriver bits (15) can be inserted using a universal bit holder with ball catch (14).
Removing Pull the locking sleeve (2) forward and remove the application tool. GDS 12 V-115: When working with an application tool, pay attention that the application tool is connected securely to the tool holder. When the application tool is not securely connected with the tool holder, it can come off during application. Slide the application tool (16) onto the square drive of the tool holder (1). Due to the way the system operates, the application tool (16) will move around slightly in the tool holder(1); this has no influence on the function/safety.

Operation

Method of Operation

The tool holder  1 with the application 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 load is therefore put on the motor. The impact mechanism then converts the power of the motor to steady rotary impacts. When loosening screws or nuts, the process is reversed.

Starting Operation

Inserting the Battery
Set the rotational direction switch (9) to the middle position to avoid unintentionally switching it on. Insert the charged battery (8) into the handle until you feel it engage and it is flush with the handle. Set the rotational direction. The rotational direction switch (9) is used to change the ro-tational direction of the power tool. However, this is not possible while the on/off switch (10) is being pressed. Right rotation: To drive in screws and tighten nuts, press the rotational direction switch (9) through to the left stop.

Left Rotation
To loosen and unscrew screws and nuts, press the rotational direction switch (9) through to the right stop.

Switching on/off
To start the power tool, press and hold the on/off switch (10). The lamp (3) lights up when the on/off switch (10) 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 (10).

Adjusting the Speed
You can adjust the speed of the power tool when it is on by pressing in the on/off switch (10) to varying extents. A light pressure on the on/off switch (10) results in a low rotational speed. Increased pressure on the switch causes an increase in speed.

Preselecting the speed/impact rate
You can use the button (6) to preselect the required speed/impact rate in two stages. Press the button 6 repeatedly until the required setting appears in the speed indicator (5). The selected setting will be saved. The required speed/impact rate is dependent on the mater-ial and the work conditions and can be determined by practical trials.

Switching the Power Light lamp on/off
Press the button (4) to activate the lamp (3). To switch off the lamp (3), press the button (4) again.

Battery charge indicator
When the on/off switch (10) is pressed in halfway or completely, the battery charge-control indicator (11) indicates the charge condition of the battery for several seconds. The indicator consists of three green LED

Temperature dependent overload protection
In normal conditions of use, the power tool cannot be over-loaded. If the power tool is overloaded or the permitted battery temperature is exceeded, the electronics of the power tool will switch off until the temperature returns to within the optimum operating temperature range.

Practical advice
Only apply the power tool to the screw/nut when the tool is switched off. Rotating tool inserts can slip off. The torque depends on the impact duration. The maximum achieved torque results from the sum of all individual torques achieved through impact. Maximum torque is achieved after an impact duration of 6–10 seconds. After this duration, the tightening torque is increased only minimally. The impact duration is to be determined for each required tightening torque. The tightening torque actually achieved should always be checked with a torque wrench. Screw applications with hard, spring-loaded or soft seats When the achieved torques in an impact series are measured during a test and transferred into a diagram, the result is the curve of a torque characteristic. The height of the curve corresponds to the maximum achievable torque, and the steep-ness indicates the duration in which this is achieved. A torque characteristic 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 a metal-to-metal screw application which uses washers.
• After a relatively short impact duration, the maximum torque is achieved steep characteristic curve.
• An unnecessarily long impact duration only causes damage to the machine.
• A spring loaded seat is also a metal-to-metal screw application but uses spring washers, disc springs, studs or screws/nuts with conical seats.
• It is also called a spring-loaded seat when extensions are used.
• A soft seat is a screw application of e.g. metal on wood or a screw application that uses lead washers or fibre washers as backing.
• For a spring-loaded seat, as well as for a soft seat, the maximum tightening torque is lower than for a hard seat. A much longer impact duration is also required.

Guide values for maximum screw tightening torques

 

Figures given in Nm; calculated from the tensional cross-section; utilization of the yield point: 90% (with friction coefficient µtotal = 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 pre-drill a pilot hole with the core diameter of the thread to approx. 2/3 of the screw length. Ensure that no metal particles enter the power tool. You can use the belt clip (17) to hang the power tool on a belt, for example. You then have both hands free and the power tool is always at hand. Coloured clip  you can use the coloured clip  to individually identify the power tool.
Recommendations for optimal handling of the battery Protect the battery against moisture and water. Only store the battery only within a temperature range of -20 to 50 °C. Do not leave the battery in your car in the summer, for example. Occasionally clean the ventilation slots on the battery using a soft brush that is clean and dry. A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.

Maintenance and Servicing

Maintenance and cleaning

Remove the battery from the power tool before carrying 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. To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.
