ure 1 for the diaphragm sub as sem bly.
To prevent damage to body, use soft jaws when
placing body in a vise.
SPRINGS UNDER COMPRESSION.
re mov ing spring chambers, relieve range
spring com pres sion by turn ing 2nd stage knob
(4) CCW until ro ta tion comes to a com plete stop.
Fail ure to do so may result in flying parts that
could cause personal injury.
B. 2nd Stage Diaphragm Replacement:
1. Securely install the body (1) in a vise with
knob (4) directed upwards.
2. Relax 2nd stage range spring (15) by turn-
ing knob (4) CCW until rotation comes to a
com plete stop. NOTE: It is not necessary
to remove knob (4) before re mov ing spring
cham ber (6) from the body (1).
3. Remove the spring chamber (6) by grasp ing
the flats and turning CCW. NOTE: Upon
re mov al, the range spring (15), range spring
clip (16), and spring button (5) should re main
inside the spring cham ber.
4. Remove 2nd stage diaphragm subassembly
(7) con sist ing of the actuator nut (7.3), di a-
