Using the Milwaukee 2463 - 20 Impact Wrench is a breeze. First, make sure the battery is fully charged. You can check the battery level using the on - board fuel gauge. Attach the appropriate socket to the 3/8' anvil with the friction ring for quick changes. Then, position the wrench on the fastener and start the tool. It's powerful enough to handle tough jobs, but always use it with care. When not in use, store it in a dry place. Keep the tool clean by wiping it down after each use. Charge the battery regularly, and if you're not going to use it for a long time, store the battery at about 50% charge. Remember, the tool comes with a 5 - year warranty, so if you have any problems, reach out to the manufacturer.
