This document provides essential information for the Bosch Professional GSR 18V-150 C and GSB 18V-150 C cordless drill/drivers. Key operations include battery installation, tool changing, and mode selection. Always ensure the auxiliary handle is securely attached before use.
Device description
The tool is designed for driving and loosening screws and for drilling in wood, metal, ceramic, and plastic. The GSB model is additionally designed for impact drilling in brick, masonry, and stone. Data and settings can be transferred via Bluetooth Low Energy Module GCY 42.
