Using the Milwaukee 2462-20 is easy. First, make sure the battery is fully charged. You can check the on - board fuel gauge to see the battery level. Once it's charged, simply attach the appropriate bit to the 1/4" hex chuck. Hold the tool with the ergonomic handle for a comfortable grip. When you start the tool, the high - speed motor will start working at 0 - 2,500 RPM, allowing you to quickly fasten screws. As for the torque, the impact mechanism delivers 1,000 in - lbs, which is great for most fastening jobs. When not in use, remove the battery and store the tool in a dry place. Keep the tool clean by wiping it down after each use. If you notice any issues, refer to the 5 - year warranty for support. Charge the battery for 30 minutes to get a full 1.5Ahr capacity. Also, don't forget to use the belt clip to keep the tool within reach when you're working.
