Using the DeWalt DCF630D2 drywall screwgun is easy. First, charge the two included 20V MAX* 2.0Ah batteries. Then, insert a battery into the screwgun. To start using it, choose the appropriate mode from the four available ones (Trigger High Speed, Trigger Low Speed, PushStart, or Lock - On) using the top - mounted mode selector. For different types of drywall or substrates, adjust the speed setting according to the job. When driving screws, use the adjustable nosecone to set the right screw depth. The LED light on the tool can be very helpful in dark work areas. Remember to keep the tool clean after each use. Wipe it down with a dry cloth to remove dust and debris. If you want to use the Tool Connect™ feature, insert the Tool Connect™ Chip (sold separately) into the chip pocket and connect it with the Tool Connect™ Site Manager app on your device. Also, store the tool in the provided kit bag to protect it from damage and keep all the parts together. And make sure to handle the tool with care to avoid any personal injury.
