tor adjusting knob counterclockwise until the
adjusting spring pressure is released.

ly a fraction of a turn. When the cylinder pressure
gauge pointer stops moving, open the valve fully.

Never stand directly in front of or behind the flow
regulator when opening the cylinder valve. Always
stand to one side.
