1. Connect the pressure regulator to your device using a hose with a quick disconnection device.
2. Before connecting the gas cylinder, please ensure that the output pressure of your gas cylinder valve (the input pressure of the regulator) is lower than 1000psi.
3. Then, use an Allen wrench to loosen the pressure regulating screw counterclockwise. (If the regulator has no pressure or needs to be readjusted, first loosen the pressure regulating screw, reconnect the gas cylinder and then adjust the pressure; otherwise, the pressure gauge and quick coupling will be damaged.) Because if the screw is tightened clockwise, the input pressure will be completely released immediately after connecting the gas cylinder.
4. Tighten the regulator onto your gas cylinder, with an initial pressure of approximately 40psi. Then slowly tighten the pressure adjusting screw clockwise to reach the pressure you need. The maximum pressure can only be adjusted to around 160psi.
