There is only one valve to set PSI. Like I said, this is only a cheap compressor so I dont expect much from it. However, next time it will be a kick azz one semi commercial type.
I'll post a pic (not running) of the front and back where the valve/connection is. I have it set at 90psi due to the bodgey gun ....
