First time using this machine, I started pressurizing and as it reached about 90-100 PSI, it started making a metallic rattling sound, as if something inside the machine was being thrown around (as opposed to the loud pressurizing sound that the compressor should be making). I switched it off and tried to inspect it from the outside but could not see any issues. I switched it on once more, this time with video in case I can get someone to diagnose the issue (see upload), and quickly switched it See full review
