GENERAL CONVENTIONS
Unless otherwise instructed, the following terminology and tech-
niques are assumed:
1.
When instructed to remove, unscrew, or
part, turn the part counterclockwise.
2.
When instructed to install, screw in, or tighten a threaded
part, turn the part clockwise.
3.
When instructed to remove an o-ring, use the pinch method
(see figure) if possible, or use a brass or plastic o-ring
removal tool. Avoid using hardened steel picks, as they may
damage the o-ring sealing surface. All o-rings that are re-
moved are discarded and replaced with brand new o-rings.
Pinch Method
Press upwards on sides
of o-ring to create a
protrusion. Grab o-ring
or insert o-ring tool at
protrusion.
4.
The following acronyms are used throughout the manual:
MP is Medium Pressure; HP is High Pressure; LP is Low
Pressure.
5.
Numbers in parentheses reference the key numbers on the
exploded parts schematics. For example, in the statement,
"...remove the o-ring (8) from the venturi switch (9)...", the
number 8 is the key number to the venturi switch o-ring.
DISASSEMBLY PROCEDURES
NOTE:
Before performing any disassembly, refer to the
exploded parts drawing, which references all mandatory
replacement parts. These parts should be replaced with
new, and must not be reused under any circumstances
- regardless of the age of the regulator or how much use it
has received since it was last serviced.
CAUTION:
Use only a plastic or brass o-ring
removal tool (p/n 944022) when removing o-rings
to prevent damage to the sealing surface. Even
a small scratch across an o-ring sealing surface
could result in leakage. Once an o-ring sealing
surface has been damaged, the part must be
replaced with new. DO NOT use a dental pick, or
any other steel instrument.

1.
While holding the inlet
fitting (13) of the second
stage secure with a 3⁄4"
(19mm) open end wrench,
apply 11/16" (17mm) open-
end wrench to the female
fitting of the LP hose (25).
Turn the fitting counter-
clockwise to loosen and
remove the hose from the
second stage. Remove the
O-rings (24&27) from the
hose and discard. Set the
hose aside.
2.
Slide back the hose pro-
tector (26) and check that
the crimps look good and
that the hose is not pulling
out. If the hose is torn or is
pulling out of the crimps, it
should be replaced.
3.
To remove the mouthpiece clamp (5), simply lift the lever
on the cam latch with a screwdriver or thumbnail. Pull the
mouthpiece (6) off. Inspect the mouthpiece to ensure it is
free of any tears or cuts that may cause leakage of water
into the second stage or other discomfort. Discard the
mouthpiece or set it aside to be reused, depending on its
condition.
