Using the DeWalt DCK299P2LR is a breeze. First, charge the two 5 Ah batteries using the included charger. Once charged, insert a battery into either the hammer drill or the impact driver. For the hammer drill, choose the appropriate bit and secure it in the heavy - duty chuck. You're ready to drill holes or drive screws. The impact driver has three - speed settings; select the one that suits your task for better control. When working on a job site, use the LANYARD READY™ attachment points to tether the tools and battery to a rigid structure to prevent them from falling. As for maintenance, keep the tools clean after each use. Wipe off any dust or debris. Don't expose the batteries to extreme temperatures. If the tool isn't working properly, check the battery connection and the bit. If problems persist, contact DeWalt customer service.
