Using your DeWalt DCF891P2 impact wrench is a breeze. First, charge the DCB205 5.0Ah batteries fully using the included charger. Then, insert the battery into the tool. You can select the appropriate speed mode using the 4 - mode push - button switch according to your task. For example, use lower speeds for more delicate jobs and higher speeds for tougher fastening. When using the tool, make sure to hold it firmly. The Precision Wrench™ setting is there to help you avoid overtightening or run - off, so take advantage of it. If you're working in a dark area, turn on the on - tool LED work light. As for maintenance, after each use, wipe the tool clean with a dry cloth. Keep the batteries in a cool and dry place. Periodically check the tool for any signs of damage. If you notice any issues, don't use the tool and contact DeWalt customer service.
