4. Set recommended working pressures by means of the adjusting screw on
the regulators.
5. Purge the hose briefl y with gas by opening the oxygen valve (4). Long hos-
es and/or small cutting nozzles require somewhat longer purges. Close the
oxygen valve (4).
6. Open the fuel-gas valve (3) and purge as above. Maintain suffi cient fuel-gas
