Using the DeWalt DCH911Z2 is easy. First, charge the DCB615 15 Ah batteries with the DCB112 fast charger. Then, insert the charged battery into the chipping hammer. When you're ready to work, hold the hammer with the rear - handle design for comfort. Use it for horizontal or downward chipping tasks on mid - to - lower walls and floors. If you have the DCV585 dust extractor, you can connect the hammer to it using the wireless tool control technology for a cleaner work environment. Remember to keep the hammer in the provided case when not in use. Also, if you attach a DEWALT Tag to the hammer, you can easily track its location via the DEWALT Tool Connect app. For maintenance, regularly check the brushless motor and clean the hammer after each use to ensure its long - term performance.
