NOTE:
You may encounter a new revision spring carrier. This
was an inline change made as a cost savings. Either version of
the spring carrier is acceptable to use.
Original Spring Carrier
8
Remove the spring adjuster (22) from the diaphragm clamp
(21) using a 6mm hex key. Using a LP air nozzle inserted into
the MP port, blast a small amount of air into the first stage to
remove the diaphragm (3). Keep your finger over the diaphragm
to prevent it from ejecting. Discard diaphragm.
CAUTION: Never remove the diaphragm by prying or dig-
ging around the edges. This will cause irreversible dam-
age to the first stage body.

Remove the valve lifter (4) out of the first stage body (5).
Insert a 6mm hex key into the end of the turret retaining bolt
(15) and turn counter-clockwise to remove. Remove the spring
(12) and HP valve (11).

top of the turret (8). Remove o-ring (7) from the body (5).
