Ya, I was thinking about it after I wrote it and it doesn’t make any sense. The compressor is empty when you start so there’s no load, and it gradually increases. The regulator is never going to get dicked around with ever again, so what’s the point? Maybe to let moisture out? Metal shavings? Sounds like dumb instructions that everyone will ignore. Maybe it’s a way to void the warrenty? “Sorry to hear your brand new compressor shit the bed, did you remember to fuck around with the regulator on startup? No? Sorry, we can’t help you”
