Using the DeWalt DCF809B impact driver is a breeze. First, make sure you have a fully - charged 20V MAX* battery (sold separately). Insert the appropriate 1/4 - inch bit into the driver. For delicate surfaces, use the variable - speed trigger to control the power and get precise results. When working in dark areas, the three LEDs will automatically light up to help you see what you're doing. Remember to attach the belt clip if you want to carry the tool around easily. As for maintenance, after each use, wipe down the tool with a clean, dry cloth. Store it in a cool, dry place. Avoid using the tool in wet conditions. If you notice any issues with the performance, check the warranty. The tool comes with a 3 - year limited warranty, so you can get it fixed or replaced if needed.
