7. If the hissing has stopped properly, continue turning the knob
felt. Breathe on the regulator. It should breathe fairly hard at this setting, but still deliver a good
air supply.
8. Check the purge button for proper operation.
9. After setting the poppet screw
plate and the tip of the lever
retaining ring. The tip of the lever should just barely touch the diaphragm. If when touching the
diaphragm lightly with the finger there seems to be a significant gap between the lever tip and
diaphragm, remove the diaphragm and bend the lever slightly upwards using the fingers. If the
regulator hisses slightly when the air is turned on, but stops hissing when the diaphragm is
removed, then the lever is too high. Use Sherwood's lever bending tool (p/n 4005-16) to bend
the lever slightly downward as shown in Photo #5. There are two indentations at the proper
lever bend point.
10. Replace the diaphragm and test the gap between the lever and the diaphragm again after each
bending. Lever bending is usually necessary only when a new lever is being installed in the
regulator. If you are re-using the same major parts of the regulator, this measurement will most
likely be correct, and no adjustment will be needed. In fact bending the lever should be avoided
unless necessary to get the tip of the lever in the proper position.
