1) Remove the regulator cover clamp screw and
clamp.

The SuperFlow 350 regulator assembly.
3) Adjustment knob removal is started by unscrewing
the adjustment knob until it stops.
4) The packing nut is now exposed enough to use a
wrench on it for removal. As the nut is backed off,
unscrew the knob also.
5) The O-ring and washer will remain on the adjust-
ment shaft.
6) Tilt the helmet so that the spacer, spring set, and pis-
ton fall out of the adjustment tube of the regulator.
NOTE: If the spacer and the spring set are stuck,
this indicates possible corrosion or saltwater intru-
sion into the adjustment tube or the adjustment tube
may be bent. The demand regulator requires removal
from the helmet and cleaning per this Chapter and
This occurs if the helmet were dropped on the ad-
justment knob or the diver hit the adjustment knob
against a rigid object. Repairs must be made by a
trained KMDSI technician.
7) On the adjustment knob, drive out the roll pin using
a 3/32 punch. Use a block of wood with a 1/4 ” hole
