Using the Bosch RH1255VC rotary hammer is easy. First, select the right bit for your job and use the SDS - max toolless bit system to insert it. Adjust the Vario - Lock to set the chisel at the perfect angle. Plug the tool into a 120V power source and choose one of the two drilling speeds based on your task. When starting, the Constant Response circuitry will give you a smooth start and maintain a steady speed. Remember to hold the auxiliary side handle firmly to reduce vibrations and for better control. During use, don't overload the tool. If you notice any abnormal noises or vibrations, stop using it immediately. For maintenance, after each use, clean the tool with a dry cloth. Check the cord regularly for any damage. Keep the tool in the provided carrying case when not in use to protect it from dust and damage.
