Quick guide from the manual
The Bosch GDS 18V-300 Professional is a cordless impact wrench designed for driving and loosening screws and bolts, as well as tightening and loosening nuts. Key features include the ABR (Auto Bolt Release) function, which automatically stops the tool when a nut is loosened to prevent it from falling.
Product Description
The tool features a 1/2" square drive tool holder, a belt clip, and a built-in LED work light (PowerLight). It is compatible with Bosch GBA 18V and ProCORE18V batteries.
Assembly
Always remove the battery before performing any maintenance, changing tools, or transporting the device to prevent accidental activation. To insert the battery, push it into the base of the tool until it locks securely. To remove, press the battery release button and pull the battery out.
Operation
The tool is driven by an electric motor via a gear and impact mechanism. The impact mechanism activates when the screw connection becomes tight. The ABR function can be toggled using the dedicated button; when active, the ABR LED lights up.
Maintenance and Cleaning
Regularly clean the air vents to prevent dust accumulation, which can cause electrical hazards. Keep the tool and ventilation slots clean for safe and efficient operation.
