& closing should therefore be adopted.
5.3. Check that both oxygen & gas valves of the shank as well as the regulator adjusting
valves are closed. SLOWLY open the gas cylinder valves.
5.4. Set on the oxygen & gas regulators the recommended working pressure for each
thickness (see table 8).
5.5. Open one turn, first the oxygen valve on the shank & wait that oxygen flows out; it will
produce a noise in the flexible hose. Follow same procedure for the fuel gas valve of the
torch.
5.6. Light the flame preferably with special gas lighter.

the flame variation pushing on the oxy-cutting lever, while adjusting with the valves if
necessary. Check on regulators that preset pressures remain the same. On the
contrary, adjust till the recommended values are reached.
5.8. Adjust the torch by cutting with pre-heating flame on the side of the sheet metal till
reaching the suitable heat. Fully open the valve for cutting oxygen & push on at
