Quick guide from the manual
The Bosch GSR 18 V-EC TE Professional is a cordless screwdriver designed for driving in and loosening screws. This document provides essential information on safe operation, battery management, and tool adjustments. Always remove the battery before performing maintenance or changing accessories to prevent accidental activation.
Operation
To start the tool, press and hold the On/Off switch. The integrated LED illuminates the work area when the switch is partially or fully pressed. Use the lock-on button to keep the tool running during continuous use.

Reversing Rotation
The rotational direction switch allows you to change the direction of the bit. Ensure the switch is in the center position to prevent accidental starting when not in use. Move the switch to the left or right stop to select the desired rotation.
Adjusting Screw-in Depth
Use the adjustment sleeve to preset the screw-in depth. Each of the 8 locking steps per full turn corresponds to a 0.25 mm change in depth. Turning clockwise increases depth, while counter-clockwise decreases it.
Maintenance and Cleaning
Always keep the machine and ventilation slots clean for safe operation. Before any maintenance or transport, remove the battery pack. If the battery is no longer functional, contact an authorized Bosch service center.
Safety
Use only original Bosch lithium-ion batteries. Protect the battery from heat, fire, water, and moisture. Do not open the battery pack. When working, wear appropriate personal protective equipment, including eye protection.
