as you stand in front of the regulator the gauge on your right is the one that tells you how much psi of gas is in the co2 bottle, you cannot adjust that , it`s like your fuel gauge in your car.
The one on your left is the working pressure gauge which is adjusted by the black knob centre of the regulator - turning it to the right ( clockwise) will raise your working pressure, that is the one you want set between 20 - 30 PSI, as mentioned the manual says 10 but the bubble rate is much more consistent between 20-30 PSI.
The Brass needle valve is what will fine tune your bubble rate.
hope that helps
