Using the DeWalt DCF911B impact wrench is easy. First, attach the appropriate socket to the hog - ring anvil. You can do this quickly and securely. Then, connect your compatible 20V MAX* battery (not included). When you need to loosen or tighten bolts, lug nuts, or other fasteners, simply position the socket over the fastener and pull the trigger. The tool will deliver powerful torque to get the job done. In low - light areas, turn on the on - board LED for better visibility. Remember, since the battery is not included, make sure you have a fully - charged one before starting your work. When not in use, keep the tool in a dry place. Periodically, check the anvil and the moving parts for any signs of wear or damage. If you notice any issues, stop using the tool and have it inspected. Also, clean the tool regularly to keep it in good working condition.
