The Bosch GTB 185-LI is a cordless drywall screwdriver designed for driving and loosening screws. Key features include a PowerSAVE mode for energy efficiency, an adjustable depth stop for precise screw-in depth, and a reversible depth stop for easy screw removal.
Product Description
The tool features a 1/4" internal hexagon tool holder, a reversible depth stop, and an adjusting sleeve for depth control. It is powered by an 18V battery system. The tool includes an LED light for illuminating the work area and a belt clip for convenience.
Operation
Inserting and Removing the Battery
Push the charged battery into the handle until it clicks into place. To remove, press the battery release button and pull the battery out. Do not use force.
Switching On/Off and Speed Control
Press and hold the on/off switch to start the tool. The speed is controlled by the pressure applied to the switch. Use the lock-on button to lock the switch in the on position.
PowerSAVE Mode
To activate PowerSAVE mode, press the PowerSAVE on/off button. The PowerSAVE LED will light up. Then, press the on/off switch and lock it. The motor remains deactivated until the tool is pressed against the workpiece.
Adjusting Screw-in Depth
Turn the adjusting sleeve to the desired depth. The scale on the sleeve serves as a guide. Turning clockwise increases depth; turning counter-clockwise decreases it.

To loosen screws, align the arrows on the adjusting sleeve and the gearbox. Pull the adjusting sleeve backwards until it clicks into place. The screwdriver bit will be exposed, allowing for screw removal.
