Using the DeWalt DCM848B is easy. First, make sure the battery is fully charged. You can hold it by the front grip or the side handle, depending on what's more comfortable for you. Before you start polishing, adjust the speed using the trigger and the dial according to the job you're doing. For example, if you're working on a delicate surface, use a lower speed. When polishing, move the polisher in a smooth, circular motion. Keep in mind that the 2.1 - inch orbit diameter and 5 - inch backing plate are great for most jobs. As for maintenance, after each use, clean the polisher with a dry cloth. Check the brushless motor regularly for any signs of damage. Store it in a dry place to prevent rust and other issues. Also, always follow safety guidelines, like wearing safety goggles when using the tool.
