Using your DeWalt DCF892B Impact Wrench is easy. First, make sure you have a compatible 20V battery (sold separately) and insert it properly. Then, select the appropriate speed setting using the 4 - mode push button switch based on the job you're doing. You can also use the variable - speed trigger for more control. When using the wrench, the Precision Wrench™ setting helps you avoid overtightening or fastener run - off. Just be careful not to use it with a damaged battery or charger. For maintenance, keep the wrench clean by wiping it down after each use. Check the anvil and other moving parts regularly for any signs of wear or damage. If you notice anything wrong, don't use the tool until it's been repaired. Also, store the wrench in a dry and cool place when not in use.
