5.IMPORTANT! The Pressure Adjusting Screw on the Acetylene Regulator (not included) and the Pressure Adjusting Screw on the Oxygen Regulator (not included) should be opened slightly by turning counterclockwise to relieve pressure on the regulator diaphragms before opening the cylinder valves. If this is not done, pres- sure from the cylinders may damage the diaphragms and render the regulators inoperable. (See Figure B.)

6.Check connections for leaks. Adjust the Acetylene Regulator and Oxygen Regulator operating pressure to coincide with the Tip used (1, 12, 13, 14, 15). Use an approved leak detection solution to check for leaks at the Welding Hoses (7, 8) and cylinder valve connections. If leaks are found, tighten the nuts more securely. If a leak still persists, discontinue use and call your gas supplier. (See Figures B and C.)

7. WARNING! NEVER set the Acetylene Regulator to a delivery pressure above that of which is required for a specific Tip (1, 12, 13, 14, 15) used. (See Figures B and C.)
