8Never apply oil or grease to any thread.
9For safety advice regarding gas bottles refer to the supplier of the bottles.

3. OPERATION
3.1. Make sure that the cylinder is secure as noted in safety precautions.
3.2. Whilst standing to one side ‘crack’ each cylinder valve. ‘Cracking’ is to quickly open and close the valve allowing gas to escape
and clear the valve of any foreign bodies.
WARNING! If grease or oil is found, discontinue use of cylinder immediately and contact your gas supplier.
3.3. Attach the regulator to the cylinder.
3.3.1. A wrench should be used to ensure tight connections. To tighten turn anti-clockwise.
3.3.2. The regulator adjusting screw should be turned anti-clockwise to relieve the pressure on the diaphragm before opening the cylinder
valves. If this is not done, pressure from the cylinder can damage the diaphragm and render the regulator inoperative.
3.3.3. Both cylinder valve-to-regulator connections should be checked for leaks. Stand so that the cylinder valve is between you and the regulator.
Slowly open the cylinder valve. Use an approved leak detector.
3.3.4. Connect a BLUE hose to the regulator. Tighten nut securely with wrench. If any sign of oil or grease is found, discontinue use
immediately.
3.4. Blowing out hoses.
3.4.1. Perform this on the hose in a well ventilated area, otherwise you may create conditions for fire or explosion.
a. Turn the regulator adjusting screw to allow 5psi to pass through hose.
b. Allow oxygen to flow approximately 10 seconds to purge the hose.
Note: New hoses contain a preservative talc which must be blown out before use.
3.4.2. On completion close the cylinder valve.
3.4.3. Drain gas from the regulator by opening the valve on the torch.
3.4.4. Release adjusting screws on the regulator by turning it anti-clockwise.
