Using the Bosch GBH18V-24CN rotary hammer is straightforward. First, choose the right bit for your job and insert it into the SDS-plus® chuck. It's keyless, so it's easy to install and remove bits. Then, select the appropriate operation mode - rotary hammer, rotation only, or hammer only - using the function selector. The variable-speed trigger allows you to start the bit accurately. When drilling overhead or in tight spaces, the ergonomic L-shaped design and 360-degree side handle give you better control. The LED worklight will help you see in dark areas. For safety, always wear appropriate protective gear, like goggles and gloves. The KickBack Control reduces the risk of sudden tool reactions, but still be careful when using the tool. To maintain your hammer, keep it clean after each use. Wipe off any dust or debris. The brushless motor is efficient, but don't overwork the tool to extend battery life. If you want to customize settings, connect the tool to the Bosch Toolbox app via the integrated connectivity feature. This way, you can get the most out of your Bosch GBH18V-24CN rotary hammer.
