Using the DeWalt DCF891B impact wrench is easy. First, make sure you have a fully - charged battery (battery and charger sold separately). Attach the appropriate bit or socket to the hog ring anvil. You can choose from 4 speed settings using the push - button switch and control the speed precisely with the variable - speed trigger. For different jobs, pick the right speed to get the best results. When you're using it, be careful not to overtighten. The Precision Wrench setting helps with that. If you're working in the dark, turn on the LED work light on the tool. After using the tool, clean it with a dry cloth to remove dust and debris. Store it in a dry place. Also, check the anvil and other moving parts regularly for any signs of wear. If you notice any issues, get it serviced by a professional.
