Set the regulator while checking thedisplayed values of the inlet and outletpressure gauges. Turning the knobexcessively can cause damage to theinternal parts.2. The pressure gauge included withregulators for 0.02 to 0.2MPa setting is forup to 0.2MPa use. Exceeding 0.2MPa ofpressure can damage the gauge.3. Do not use tools on the pressure regulatorknob as this may cause damage. It must beoperated manually.Caution1. Be sure to unlock the knob before adjustingthe pressure and lock it after setting thepressure.Failure to follow this procedure can causedamage to the knob and the outlet pressuremay fluctuate.• Pull the pressure regulator knob to unlock.(You can visually verify this with the "orangemark" that appears in the gap.)• Push the pressure regulator knob to lock.When the knob is not easily locked, turn itleft and right a little and then push it (whenthe knob is locked, the "orange mark", i.e.,the gap will disappear).Orange mark0.150.15000.20.30.4 0.5 0.6 0.7 0.8Inlet pressure MPa0.91000.20.30.4 0.5 0.6 0.7 0.8Inlet pressure MPa0.91AW30KAW40K-060.250.25Outlet pressure MPa0.20.15000.20.30.4 0.5 0.6 0.7 0.8Inlet pressure MPaSet point0.91Outlet pressure MPa0.20.15000.20.30.4 0.5 0.6 0.7 0.8Inlet pressure MPaSet point0.912.
