Safety Instructions

General Power Tool Safety Warnings
WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions 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 (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 or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension 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 unavoidable, 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. u 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 extraction 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 injury 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 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 remove 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 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.
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 battery packs should only be performed by the manufacturer or authorized service providers.

Safety Warnings for Impact Wrenches

Hold the power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring. Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Use suitable detectors to determine if there are hidden 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 explosion. Breaking water pipes causes property damage.
Hold the power tool securely. When tightening and loosening screws be prepared for temporarily high torque reactions.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Always wait until the power tool has come to a complete 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, vapours may be emitted. The battery can set alight or explode. 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-circuiting.
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 in the manufacturer’s products. This is the only way in which you can protect the battery against dangerous overload.
Coin cells must never be swallowed or inserted into any other part of the body. If you suspect that someone has swallowed a coin cell or that a coin cell has entered the body in another way, seek medical attention immediately. Swallowing coin cells can result in severe internal burns and death within 2 hours.
Ensure that coin cell replacement is carried out properly. There is a risk of explosion.
Only use the coin cells listed in this operating manual. Do not use any other coin cells or other forms of electrical power supply.
Do not attempt to recharge the coin cell and do not short-circuit the coin cell. The coin cell may leak, explode, catch fire and cause personal injury.
Remove and dispose of drained coin cell correctly. Drained coin cell may leak and damage the product or cause personal injury.
Do not overheat the coin cell or throw it into fire. The coin cell may leak, explode, catch fire and cause personal injury.
Do not damage the coin cell and take the coin cell apart. The coin cell may leak, explode, catch fire and cause personal injury.
Do not allow damaged coin cells to come into contact with water. Leaking lithium may mix with water to create hydrogen, which could cause a fire, an explosion, or personal injury.

Noise/vibration information
Noise emission values are determined according to EN 62841-2-2.
Typically, the A-weighted noise level of the power tool is: Sound pressure level 97 dB(A); and sound power level 105 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:
Tightening screws and nuts of the maximum permitted size: ah = 20.3 m/s2, K = 1.5 m/s2
The vibration level and noise emission value given in these instructions have been measured by 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 accessories 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 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 accessories, keeping their hands warm, and organising workflows correctly.

Rechargeable battery

Bosch sells some cordless power tools without a rechargeable battery. You can tell whether a rechargeable battery is included with the power tool by looking at the packaging.

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: Lithium-ion rechargeable batteries are supplied partially charged according to international transport regulations. To ensure full rechargeable battery capacity, fully charge the rechargeable battery before using your tool for the first time.

Inserting the Battery
Push the charged battery into the battery holder until it clicks into place.

Removing the Battery
To remove the rechargeable battery, press the battery release button and pull the battery out. Do not use force to do this.
The rechargeable battery has two locking levels to prevent the battery from falling out if the battery release button is pressed unintentionally. The rechargeable battery is held in place by a spring when fitted in the power tool.

Battery charge indicator
Note: Not all battery types have a 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. If no LED lights up after pressing the button for the battery charge indicator, then the battery is defective and must be replaced.

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.
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.

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.

Changing the Tool

Inserting the application tool (see figure A)
Insert the application tool all the way into the tool holder (1). Screwdriver bits (13) can be inserted using a universal bit holder with ball catch (14).
NOTE: If the application tool does not go in easily, pull the locking sleeve forward and then push the application tool into the tool holder as far as it will go.
NOTE: Make sure that the application tool clicks into place and is secure.
Removing
Pull the locking sleeve (2) forward and remove the application tool.\
Inserting the Bluetooth® Low Energy Module GCY 42 (Accessory)
Read the corresponding operating instructions for information about the Bluetooth® Low Energy Module GCY 42.

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

Set the rotational direction (see figure B)
The rotational direction switch (3) is used to change the rotational direction of the power tool. However, this is not possible while the on/off switch (9) is being pressed.
- Right rotation: To drive in screws and tighten nuts, press the rotational direction switch (3) through to the left stop.
- Left Rotation: To loosen and unscrew screws and nuts, press the rotational direction switch (3) through to the right stop.
Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when it is on by pressing in the on/off switch (9) to varying extents. Applying light pressure to the on/off switch (9) results in a low rotational speed/impact rate. Applying increasing pressure to the switch increases the speed/impact rate.
Switching on/off
To start the power tool, press and hold the on/off switch (9). Worklights (10) and (18) light up when the on/off switch (9) 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 (9).
User interface (see figure C)
The user interface is used to preselect the speed and working mode and to indicate the status of the power tool.

Status indications

BOSCH-GDR-18V-220-C-Impact-Wrench-12

Speed preselection
With the speed preselection button (19), you can preselect the required speed in three stages. Press button (19) as often as needed until the required setting is indicated in the speed indicator (20). The selected setting will be saved. You can also preselect the speed using the Bosch Toolbox app.
The required speed depends on the material and the working conditions; it can be ascertained through practical tests.

You can use the button for speed preselection (19) to preselect the required speed, even during operation.

Selecting the working mode
The power tool has two preset working modes A and B (16). You can also programme working modes for different applications and adjust existing modes via the Bosch Toolbox under A and B (16).
To switch between the working modes A and B (16), press the mode button (17 ). BOSCH-GDR-18V-220-C-Impact-Wrench-14

Locking/unlocking the user interface
The user interface can be locked and unlocked using the “Lock User Interface” function in the Bosch Toolbox app.

Locking and unlocking through the user interface:

Activate the “(Un-)Lock from tool” function in the Bosch Toolbox app.
The function is now also enabled on the power tool.
To lock or unlock the user interface, press and hold both the mode button (17) and the speed selection button (19) for five seconds.
Note: If the “Lock User Interface” function is activated, the reset to factory settings option on the power tool is automatically deactivated.

Practical advice

Only apply the power tool to the screw/nut when the tool is switched off. Rotating tool inserts can slip off.
The power tool with inserted Bluetooth® Low Energy Module GCY 42 (accessory) is equipped with a radio interface. Local operating restrictions, e.g. in aircraft or hospitals, must be observed.

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 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 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 . BOSCH-GDR-18V-220-C-Impact-Wrench-15

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. BOSCH-GDR-18V-220-C-Impact-Wrench-16
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.

Belt clip
You can use the belt clip (5) to hang the power tool on a belt, for example. You then have both hands free and the power tool is always at hand.

Control Via App
The power tool can be fitted with a Bluetooth® module which enables wireless data transfer to certain mobile devices with a Bluetooth® interface (e.g. smartphone, tablet). To control the power tool via Bluetooth®, you will need the “Bosch Toolbox” app. Download the app from the corresponding app store (Apple App Store, Google Play Store).
Then select the “My Tools” sub-item in the app. The display of your mobile terminal device will show you all subsequent steps required to connect the power tool to the terminal device.
The following functions will be available when a connection has been established with the mobile device:

Grant of Patent License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of their Contribution(s) with the Work to which such Contribution(s) was submitted. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.
Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof in any medium, with or without modifications, and in Source or Object form, provided that You meet the following conditions: You must give any other recipients of the Work or Derivative Works a copy of this License; and You must cause any modified files to carry prominent notices stating that You changed the files; and You must retain, in the Source form of any Derivative Works that You distribute, all copyright, patent, trademark, and attribution notices from the Source form of the Work, excluding those notices that do not pertain to any part of the Derivative Works; and If the Work includes a “NOTICE” text file as part of its distribution, then any Derivative Works that You distribute must include a readable copy of the attribution notices contained within such NOTICE file, excluding those notices that do not pertain to any part of the Derivative Works, in at least one of the following places: within a NOTICE text file distributed as part of the Derivative Works; within the Source form or documentation, if provided along with the Derivative Works; or, within a display generated by the Derivative Works, if and wherever such third-party notices normally appear.

You may add Your own attribution notices within Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot be construed as modifying the License.
You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and
distribution of the Work otherwise complies with the conditions stated in this License.
Submission of Contributions. Unless You explicitly state otherwise, any Contribution intentionally submitted for inclusion in the Work by You to the Licensor shall be under the terms and conditions of this License, without any additional terms or conditions. Notwithstanding the above, nothing herein shall supersede or modify the terms of any separate license agreement you may have executed with Licensor regarding such Contributions.
Trademarks. This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and reproducing the content of the NOTICE file.
Disclaimer of Warranty. Unless required by applicable law or agreed to in writing, Licensor provides the Work (and each Contributor provides its Contributions) on an “AS IS” BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of using or redistributing the Work and assume any risks associated with Your exercise of permissions under this License.

Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License. However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability.
