As it is turned in (clockwise), the opening effort will increase. This will make the second stage less sensitive to sudden changes in ambient pressure.

Turning the knob “out” (counter- clockwise) will decrease the opening effort to make breathing easier. Sometimes a slight hissing may be heard in this setting. If this occurs, turn the knob clockwise just enough to stop the hissing.

Depress the second stage purge button to drain the remaining gas from the regulator and hoses. Keep the purge button pressed in until no more gas can be heard exiting the regulator.

Turn the yoke screw counterclockwise to loosen the regulator on the cylinder valve. While removing the regulator, keep the first stage inverted with the yoke screw facing down. This will prevent water drops for going in the inlet area where the filter is located.
