Using this Milwaukee compressor is easy. First, connect a compatible M18™ REDLITHIUM™ battery to the compressor. Then, you can adjust the pressure using the single - turn regulator according to your needs. When you're ready, start using it to power your nail gun or other air - powered tools. It can drive up to 1,600 18ga brad nails per charge, so you can work continuously. For safety, make sure to operate it in a well - ventilated area. Don't expose it to extreme temperatures or moisture. When not in use, store it in a dry place. To keep it in good condition, clean the compressor regularly, especially the air intake. Check the battery regularly for any signs of damage and charge it properly. If you notice any unusual noises or performance issues, stop using it and contact customer service.
