The regulator should begin to free flow once the adjustment
knob is screwed out several turns.
4) Rotate the adjustment knob out counterclockwise
slowly, until a slight steady flow develops.
5) Slowly rotate the adjustment knob in clockwise,
until the free flow stops. Lightly depress the purge but-
ton several times and ensure the gas flow has stopped.
6) Lightly depress the purge button. There should be
between 1/16" and 1/8" free travel in the button before
gas flow starts. When the button is fully depressed, a
strong surge of gas must be heard.
7) If the purge button travels less than 1/16" or greater
than 1/8" before free flow is heard, the demand regu-
lator requires internal adjustment, per this chapter.

Chapter 6 and wipe dry. Inspect the diaphragm for
holes, tears or any signs of deterioration by holding it
up to a white light and stretching and pulling. Check
for a good bond between the metal disc and the sili-
cone. Replace diaphragm if any doubt exists.
4) Inspect the interior of the demand regulator body
for damage, corrosion and cleanliness. Clean the in-
terior of the regulator body if necessary.
5) Reinstall the diaphragm, cover, and clamp. Do not
lubricate the diaphragm Tighten the clamp screw to
the recommended torque to 12 inch pounds using a
torque screwdriver.
WARNING
Use only replacement diaphragms manu-
factured by Kirby Morgan. Use of other
diaphragms may degrade performance
and may cause increased breathing re-
sistance. This can lead to fatigue and the
inability to work at full capacity.
