Tuning the Second Stages
1) Turn the adjustment knob counterclockwise until it stops;
this will set the second stage for the least resistance.
2) Using the second stage adjusting tool set the resistance to
.8-1.0 inches of water.
3) Purge the regulator and observe the intermediate pressure.
An intermediate pressure drop of 2-8 psi is considered acceptable
Note: By setting the adjustment knob to the easiest setting, the diver
can increase breathing resistance to his/her preference. The regulator
should NOT be set to FREEFLOW.
