I'm reaching out regarding a compressor issue. It currently lacks a male plug necessary to halt air flow, which is causing a significant problem as the compressor runs non-stop without proper pressure build-up. Could you provide details on how to source this part? Additionally, I've noticed that the User Manual is missing pages 8 and 9, which include the Maintenance and Troubleshooting Guide. It would be great to get a complete manual for better guidance. Thanks!
