I’m a new owner . The fill valve operation has me unsure Filling the tank seems to go ok but the disconnect has me questioning . Once the air tank is filled you are to close the valve on the air tank and then close the lever on the fill valve . What happens then is what has me in doubt. The compressor immediately goes into over pressure and the pressure relief valve opens with a pop. Seems like the fill valve handle should release pressure preventing the over pressure. The operation of the fill valve handle does not seem intuitive to me. What am I doing wrong or misunderstanding.
