7. Second Stage Testing and Adjustment

(1) Second stage testing and adjustment can be accomplished by using a regulated supply or any

cylinder of air. There is no required supply pressure due to the second stage being supplied by a first

stage delivering air at the Intermediate Pressure (IP).
(2) Using a properly tuned first stage, connect the second stage to a low pressure hose with the Second

Stage In-Line Adjusting Tool. Slowly pressurize the system with the purge button slightly depressed.

Once the second stage starts to deliver air, release the purge button. It should not continue to flow. If

it does, depressurize the system and adjust the Orifice using the In-Line Adjusting Tool. Turn the Orifice

clockwise one-sixth turn to start. Retest. Depending on where the Orifice was initially set, it may be

necessary to do this several times.
(3) If the second stage does not flow on the initial pressurization, attempt several normal breaths from

it. If the breaths require significant effort, depressurize the system and with the purge button depressed

turn the Orifice counterclockwise one-sixth turn and retest. As with the clockwise adjustment, this may

need to be done several times.
(4) Once the second stage begins to deliver air at an acceptable level, it can be fine-tuned with the

adjusting tool. While inhaling through the second stage, turn the tool’s adjustment knob slightly in the

required direction.

Caution Note: To avoid excessive wear and cutting of the low pressure seat, only

turn the Orifice using the In-Line Adjusting Tool with the purge button depressed

by inhaling or by manually pressing it while making the adjustment.
