Using the DeWalt DCH172B is easy. First, make sure you have a fully - charged battery (sold separately). Then, insert the bit into the SDS+ chuck. You can use the mode selector switch to choose between drill and hammer drill modes depending on your task. For rod hanging, concrete forming, or any of the other recommended tasks, hold the drill firmly and start at a slow speed, then increase as needed. When using it, remember to wear safety goggles and a dust mask, especially if you're not using the DWH200D shroud and DWH161D1 dust extractor. To keep your drill in good shape, clean it after each use. Wipe off any dust or debris, and store it in a dry place. Also, check the chuck regularly for any signs of wear or damage. If you notice any issues, it's best to get it serviced by a professional.
