 Connect the pressure reducer 64 to the inert
gas cylinder 60.
 Screw the inert gas hose 65 to pressure reducer
64 and open the gas cylinder valve 61.
 Start the "gas test" and set the gas quantity
with setting screw 66 of the pressure reducer.
The gas flow rate is indicated on the flow meter
63.
Rule of thumb:
Gas nozzle size = litres/min.
‰ The cylinder content is indicated on the con-
