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 95 dB(A); sound power level 106 dB(A). Uncertainty K = 3 dB. Wear hearing protection! Vibration total 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: GDR 18V-200: ah = 14.0 m/s2 , K = 1.5 m/s2 GDX 18V-200: ah = 10.0 m/s2 , K = 1.5 m/s2 GDS 18V-200: ah = 9.0 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 standardised measuring procedure and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions. The stated 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 application 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 their hands warm, and organising workflows correctly.

Assembly

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.

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.
•  Do not continue to press the On/Off switch after the power tool has automatically switched off. The battery can be damaged.
• Follow the instructions on correct disposal.

Removing the Battery

The battery (4) is equipped with two locking levels to prevent the battery from falling out when pushing the battery release button (5) unintentionally. As long as the battery is inserted in the power tool, it is held in position by means of aspring. To remove the battery (4), press the release button (5) 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 indicate the state of charge of the battery. For safety reasons, it is only possible to check the state of charge when the power tool is not in operation. Press the button for the battery charge indicator or to show the state of charge. This is also possible when the battery is removed.

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.
• Inserting the application tool 

GDR 18V-200 / GDX 18V-200:

• Pull the locking sleeve (2) forward, guide the application tool (1) into the tool holder as far as it will go and release the locking sleeve (2) to lock the application tool. Impact-proof screwdriver bits (12) can be inserted using a universal bit holder (11) with ball catch. Inserting the application tool  GDX 18V-200 / GDS 18V-200:
•  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 (13) onto the square drive of the tool holder (1).
• Due to the way the system operates, the application tool (13) will move around slightly in the tool holder (1); this has no influence on the function/safety.
• Some application tools (e.g. double bits) cannot be safely secured in the tool holder. Removing the application tool   Pull the locking sleeve (2) forward and remove the application tool.

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.

Inserting the battery

• Use only original Bosch lithium-ion batteries with the voltage stated on the type plate of your power tool. Using other batteries can lead to injuries and pose a fire hazard.
• Set the rotational direction switch (7) to the middle position to avoid unintentionally switching it on. Insert the charged battery (4) into the handle until you feel it engage and it is flush with the handle.
• Set the rotational direction
  • The rotational direction switch (7) is used to change the rotational direction of the power tool. However, this is not possible while the on/off switch (8) is being pressed.
• Right rotation:
  • To drive in screws and tighten nuts, press the rotational direction switch (7) through to the left stop.
• Left Rotation:
  • To loosen and unscrew screws and nuts, press the rotational direction switch (7) through to the right stop.
• Switching on/off
  • To start the power tool, press and hold the on/off switch (8). The LED lights up when the on/off switch (8) 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 (8).
• Adjusting the Speed
  • You can adjust the speed of the power tool when it is on by pressing in the on/off switch (8) to varying extents. A light pressure on the on/off switch (8) results in a low rotational speed. Increased pressure on the switch causes an increase in speed.

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 increases 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 with the maximum reachable torque, and the steepness 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 a metal-to-metal screw application which uses washers. After a relatively short impact duration, the maximum torque is reached (steep characteristic curve). Unnecessary 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 springloaded 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. Also, a clearly longer impact duration is 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.

Note: Ensure that no metal particles enter the power tool. After working at a low speed for an extended period, you should operate the power tool at the maximum speed for approximately three minutes without load to cool it down.

Recommendations for optimal handling of the battery

Protect the battery against moisture and water. Only store the battery within a temperature range of -20 to 50 °C. Do not leave the battery in your car in the summer, for example. A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced. Follow the instructions on correct disposal. .

Belt clip
