Using the Bosch RH745 is easy. First, choose the right operation mode. If you need to drill, select the rotary hammer mode. For just chiseling, use the hammer - only mode. Adjust the variable speed dial according to your task for better control. When using the hammer - only mode, take advantage of the Vario - Lock function to set the best working angle for the chisel. Don't forget to attach the 360 - degree auxiliary handle for better movement and comfort. Also, hold the soft - grip rear handle to reduce shock and vibration. Before using, make sure the tool is plugged into a 120V power source. When the Service Minder light comes on, it's time to do some preventative maintenance. Keep the tool clean and store it in the carrying case when not in use. And when changing bits, use the SDS - max bit system's tool - free feature for quick and easy changes.
