Using the Bosch GSR18V - 975CB25 drill/driver is easy. First, insert the CORE18V battery into the tool. Then, select the appropriate speed setting based on your task. For fast drilling, use the high - speed setting (0 - 2,100 rpm), and for tasks that need more power, choose the high - power setting (0 - 480 rpm). When driving screws, use the precision clutch to prevent over - tightening and damage to fasteners. You can switch between drilling and driving modes quickly with the rapid mode selector. If you want to customize the tool's settings, connect it to your device via the Bosch Toolbox App (module sold separately). When using the drill, always wear safety gear, like goggles. Avoid using the drill in wet conditions. After use, clean the drill with a dry cloth. Charge the battery in a cool, dry place and don't overcharge it. Keep the drill in the provided bag for storage.
