Carefully turn the air on. There should be no air leaking from the second stage with proper
intermediate pressure applied to the hose. Turn the inline adjustment tool left until you
hear a small leak and then turn the adjustment tool right until leaking stops. Then turn the
adjustment tool a further 1/8th of a turn to the right.
Check and adjust the work of breathing by attaching the Magnehelic gauge to the second
stage. Monitor the magnehelic needle on the inhalation and the exhalation effort. Adjust to
the appropriate work of breathing.
Primary 2nd Stage: 1 - 1.4 inches of water • Alternate 2nd Stage: 1 - 2.2 inches of water
The best test to check for the slightest leaks is to immerse the second stage (with no cover
or diaphragm installed) under pressure in water and look for bubbles indicating a leak. To do
this, unscrew the cover ring (8) and the diaphragm washer (7) and the diaphragm (6) from
the housing (3). Push the lever arm 2 or 3 times. Put the second stage in water and correct
the problem if leaks are found. When leak is fixed, assemble the cover ring assembly and
diaphragm again.
