This manual provides essential information for the Bosch GDS 18V-1000, 18V-1050 H, 18V-1000 C, and 18V-1050 HC cordless impact wrenches. It covers safety, assembly, operation, and maintenance. Always ensure the tool is switched off before performing any work, such as tool changes or maintenance, and remove the battery or disconnect the power plug.
Device Description
The tool features a tool holder, rotational direction switch, battery release button, and a user interface (on specific models). The GDS 18V-1000 C and 18V-1050 HC models include Bluetooth connectivity for data transfer via the Bosch Toolbox app.
Assembly
Before any work on the tool, remove the battery or disconnect the power plug. Ensure the rotational direction switch is in the middle position during transport or storage to prevent accidental activation. Slide the application tool (e.g., impact socket) onto the square drive of the tool holder.
Operation
The tool is driven by an electric motor via a gear and impact mechanism. The working procedure consists of two phases: screwing in and tightening. The impact mechanism activates when the screw connection becomes tight and the motor is under load. To change the rotational direction, use the rotational direction switch. The speed/impact rate can be adjusted by varying the pressure on the on/off switch.
Maintenance and Cleaning
Regularly clean the air vents of the tool to prevent dust accumulation, which can cause electrical hazards. Always remove the battery or disconnect the power plug before maintenance. If the battery is no longer functional, contact an authorized service center.
Safety
Always wear personal protective equipment, including eye protection. Keep the work area clean and well-lit. Do not operate the tool in explosive atmospheres. Keep children and bystanders away during operation.
