Screw the second stage to the setting gauge (HZ 710011) connected with a
middle pressure hose to a correctly set MC9 first stage (10 bars – 200 bars
tank) ;
•
Unscrew the second stage knob fully;
•
Connect the regulator (including first and second stages) with a 200 bars
pressurized tank or with an equally pressurized workbench, then open the
air tap gently, while pressing the second stage air outlet button
•
If the regulator supplies air slightly, push and turn clockwise (+) the
Bsetting gauge ring (HZ 710011) until the air stops flowing; in this way,
the valve cutting edge should hardly touch the closing pad making it work
correctly.
•
Now turn the nozzle a little more than one half turn;
•
After checking the correct set of the valve nozzle, the gauge will read the
correct set of the first stage (10 bars);
