Emglo air compressor too much pneumatic fluid, how to determine correct amount?

Your referring to central pneumatic. It is a Chicago pneumatic. Correct your wrong g answer. Don't miss lead people

I just rebuilt my Emglo AM78 4CHV, new pressure switch, unloaded, check valve, aftercooler, and changed the #30 oil, It takes 4oz.
Runs like new after not cutting in/out correctly and purging air before reaching 125 psi. Kicked it down to 115 max psi via main spring setting. Don't need 125 for trim nailing and siding.
FYI don't use cheaper generic 125 psi pressure switch from Amazon!!
use Jenny M4-1247 (140-1074-01)

pressure switch is not working /replace it

Its not getting fuel. There is a low oil shut off switch as well that go bad. most just bypass this unit. its connected to the on off switch as a 3rd leg. try that
if not check your fuel delivery. either the fuel line pet **** is closed/ clogged or a stuck needle in the carb is causing no fuel
