5. INSTRUCTIONS OF USE

EN
5.1. Connect the CS-300 shank to the flexible hoses as explained in chapter 2. Choose the
PT
suitable welding or cutting attachment & suitable nozzle for material thickness. Screw
nut of attachment on the shank, without excessive strength. In the case of cutting
application, set the suitable nozzle in the nut, screw on the attachment (apply specific
EN
instructions for the corresponding accessory).
5.2. The CS-300 torch works on the the INJECTOR principle and the following method of
lighting & 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.
5.7. Adjust with both valves on the shank until obtaining the suitable flame. Check on
regulators that preset pressures remain the same. On the contrary, adjust till the
recommended values are reached. When cutting attachment is being used, open the
"butterfly" valve (oxygen for cutting), adjust again oxygen pressure if necessary; adjust
oxygen & fuel gas flow till obtaining the right flame using both valves on the shank.
5.8. To extinguish the flame, first close the gas valve & then the oxygen one on the shank.

6. MAINTENANCE

6.1. Protect the torch from damage (check visually at regular intervals).
6.2. Clean the torch at regular intervals to avoid presence of grease or dirtiness. When
necessary, clean the holes of the cutting nozzles with the cleaning needles supplied (art
Cod. 2305203.
6.3. Check that flexible hoses are in good condition & remove parts that are damaged.
6.4. Check that connections are secured with hose clamps that cannot hurt the hose by
excessive pressure (to avoid cutting of the hose).
6.5. Replace non return valves when gas flow is reduced & every time a gas back-flowing has
happened.
