Adjust Air Pressure

The Air-Regulator Valve changes the psi (pounds/square-inch) of the air coming out of the Airbrush. Use the regulator valve to set the pressure:

1. Pull the valve outward to open it.
2. Turn the valve to the right to raise the pressure, or to the left to lower the pressure.
3. When the pressure is set, push the valve back in to close it.
