Using the DeWalt DCF850P2 is easy. First, insert a charged 20V MAX* 5.0Ah battery into the impact driver. Choose the right bit for your job and insert it into the 1/4' hex drive. You can adjust the speed using the variable 3 - speed trigger according to the task at hand. For driving large - diameter screws, you can use the high - torque and high - rpm settings. When working in dim areas, turn on the 3 - LED work light to see better. As for maintenance, keep the tool clean after each use. Wipe off any dust or debris with a dry cloth. Make sure to store the batteries in a cool, dry place. If the tool isn't going to be used for a long time, remove the battery. Also, check the bits regularly for wear and replace them if needed. Always follow the safety instructions in the user manual to avoid any accidents.
