3. Before attaching the oxygen regulator to the oxygen cylinder valve, carefully inspect the
regulator for damaged treads, dirt dust, and grease, oil, or other flammable substances.
Remove dust and dirt with a clean cloth. Be sure the inlet swivel filter is clean and in place.
Attach the regulator to the cylinder valve. Tighten securely with a wrench.
4. Before attaching the fuel gas regulator to the fuel gas cylinder valve, inspect the regulator
as in step three. Tighten securely with a wrench in the direction necessary for the particular
fuel gas connection in use.
5. Connect the gas hose to the regulator outlet fitting.
6. Before opening the cylinder valves, release the tension on the regulator adjusting screws
by turning them counterclockwise until all spring pressure is released.
Turning on the Cylinders
Be certain that the tension on the regulator adjusting screws has been released. Stand so 1.
that the cylinder valve is between you and the regulator.
WARNING
Never stand, nor have anyone stand in front or behind a regulator when opening the
cylinder valve. Always stand so that the cylinder is between you and the regulator (see
Figure 10, page 29).
2. Slowly and carefully open the oxygen cylinder valve until the maximum pressure registers
on the high pressure gauge. Now, open the oxygen cylinder valve completely to seal the
valve packing.
3. Slowly open the fuel gas cylinder valve in the same manner.
CAUTION
Open the acetylene cylinder valve approximately ¾ of a turn and no more than 1½ turns.
For all other fuel gases, open the fuel gas cylinder completely. Keep the cylinder wrench,
if one is required, on the cylinder valve so the cylinder may be quickly turned off in the
event an emergency situation arises.
