WARNING
DO NOT attach or use the regulator if oil, grease, flamma ble
substances, or damage is present! Have a qualified repair
technician clean the regulator or repair any damage.
2. Before opening the cylinder valve, turn the regulator adjusting
screw counterclockwise until there is no pressure on the
adjusting spring and the screw turns freely.
WARNING
Stand to the side of the cylinder opposite the regulator
when opening the cylinder valve. Keep the cylinder valve
between you and the regulator. For your safety, NEVER STAND
IN FRONT OF OR BEHIND A REGULATOR WHEN OPENING THE
CYLINDER VALVE!
3. Slowly and carefully open the cylinder valve (see Figure 4) until
the maximum pressure shows on the high pressure gauge. If the
regulator is of the gaugeless type, the indicator will register the
cylinder contents open.
4. On all cylinder valves, except acetylene, open the valve
completely to seal the valve packing. Acetylene cylinder valves
should be opened 3/4 of a turn and no more than 1-1/2 turns.
