I have a Hitachi Bebicon Air compressor, installed with black pipe to our school MakerSpace classroom.

How do I adjust the standing pressure for the compressor? The installer set it rather high, based on the occasional use of power nailers. But normally, we only use the compressor for a laser cutter air assist, and HVLP paint sprayer.
I cannot find any user manual to help me know how to adjust the standing pressure. Can someone teach me how to adjust? Right now, the compressor runs to maintain about 130 PSI, but I think 50 to 80 PSI would be adequate, except for the occasional times when we need to use the air nailers.
I am from the USA, teaching at an international school in Hong Kong; thus the Asian compressor.
Thank you,
Barry
