Using your DeWalt DCF900P1 Impact Wrench is easy. First, charge the 5.0 Ah battery fully using the included charger. Then, insert the battery into the tool. You can adjust the speed easily with the 4 - mode push button switch depending on the job you're doing. For jobs where you need to be careful not to overtighten, use the PRECISION WRENCH(TM) mode. When working in dark areas, turn on the LED work light. Remember, the BATTERYGUARD™ helps protect the battery, but the battery is sold separately. As for maintenance, keep the tool clean after each use. Wipe it down with a dry cloth. Don't expose the tool to extreme temperatures or moisture. If you notice any issues with the tool, stop using it immediately and have it checked by a professional. Also, store the tool in the included kit bag when not in use to keep it safe and protected.
