Second Stage Disassembly
CAUTION
: Whenever possible, use only plastic or brass
O-ring tools for removing O-rings in order to prevent dam-
age to the sealing surface. Steel instruments, such as dental
picks, can easily damage the sealing surface of a softer brass
part, causing irreparable leakage and requiring the part to be
replaced with new.
1. Slide back the hose cover to expose the connection of the LP
hose.
2. While holding the inlet fitting(20) secure with a n" open-end
wrench, apply another n" open-end wrench to the fitting of
the LP hose. Turn the fitting counter-clockwise to loosen and
remove.
3. Using a plastic or brass O-ring tool, carefully remove the O-ring
from the post inside the hose fitting.
CAUTION: When performing the above step, be very care-
ful to avoid scratching the O-ring sealing surface. Doing so
may cause a permanent leak that will require the replacement
of the LP hose.
4. Using a n" open end wrench, turn the inlet fitting counter-
clockwise to loosen, and unscrew it completely by hand to
remove.
5. Snip the plastic tie-strap(21) that holds the mouthpiece(23), and
gently pull the mouthpiece off the second stage housing(12).
Inspect the mouthpiece to ensure that it is supple and free of
any tears or corrosion. If any damage is found that could result
in discomfort or leakage, discard the mouthpiece and do not
reuse.
6. While holding the second stage secure with one hand, firmly
grasp the retaining ring(17) with the other, and turn the ring
counter-clockwise to loosen and remove it, along with the dia-
phragm cover(16).
NOTE: If the retaining ring is difficult to loosen, XS Scuba
recommends using the Rim Clamp (P/N 20-790-200), avail-
able from Peter Built Co. Complete instructions are provided
with the tool.
7. Separate the diaphragm cover from the retaining ring, and
closely inspect the cover to ensure that it is perfectly round and
free of any distortion or other damage. If any damage is found,
discard the cover and replace with new.
