Using the Bosch 1191VSRK hammer drill is easy. First, make sure it's plugged into a 120V AC power source. If you're working on concrete, use the selector lever to switch to hammer drill mode. For steel, wood, or aluminum, select the drill-only mode. The variable speed reversing switch gives you full control over the drill's operation. You can use it to drill holes, drive screws, or remove bits. The 360-degree side-handle with a depth gauge helps you drill at a consistent depth and provides a comfortable grip. When you're done using the drill, unplug it from the power source. Store it in the carrying case provided to protect it from damage. To keep your drill in good condition, regularly clean the chuck and the body of the drill. Check the cord for any signs of wear and tear. If you notice any issues, it's best to have the drill serviced by a professional.
