This has been ongoing for the last year but has gotten much worse in the last month. Usually I notice it when I try to scew the unit two plate and I hear a hiss and I lose all my air pressure (guage drops to zero) I have to close the piston that allows me to scew the plate and wait for the pressure to go back up. If I don't notice the air drop (near feeder of our SM52 and it is loud so I cant hear the air on my press) unit 2 will ink up cause the water roller wont drop till pressure is up. Lately I have notice when I run unit two on start up it will lose air pressure. Could sure use some help as to what solenoid or valve might be doing this.
