Second Stage Reassembly
WARNING: DO NOT attempt to use any other manu-
facturer's part as a substitute for any XS Scuba part,
regardless of any similarity in shape, size, or appear-
ance. Doing so may render the product unsafe, and
could result in serious injury or death.
1. Install the exhaust valve(25), if it was removed, into the
second stage housing(13) by gently pulling the stem
through the hole in the center of the sealing area, until the
barb has passed through and is securely seated against
the opposite side.
2. Mate two seating tabs on one side of the exhaust deflec
-
tor(26) into two slots inside the inner groove of the sec-
ond stage housing, and then press the opposite side until
it snaps securely into place.
3. Closely examine both sides of the white lever pad(14) to
identify that the mounting tabs on both legs are rounded
on one side and flat on the other. (See Fig. 6.) Hold
the air barrel with the
flat cut facing up
, and place the
clip over the tube with the rounded side facing toward
the flange, so that one tab engages in the hole next to it.
Then, gently press the opposite leg into place so the the
other tab engages in the opposite hole. When done cor-
rectly, the lever pad should rest flush against the flange,
with both tabs securely seated. (See Fig. 7.)
CAUTION: Do not stretch the legs of the plastic retain-
ing clip, or attempt to install it if damage or breakage
has occurred.
4. Insert the stem of the LP seat(16) into the large end of the
poppet(17). DO NOT use adhesive.
5. Lubricate and install the small O-ring(18) over the groove
on the opposite end of the poppet, being careful to avoid
stretching it excessively. Examine the poppet's features
to determine proper positioning. (See Fig. 8.)
6. While holding the air barrel with the
flat cut facing straight
down
, guide the poppet into the tube, LP seat first, with
the ears facing straight down. (See Fig. 9.)
NOTE: To better control the orientation of the poppet
inside the air barrel while the lever is being installed,
XS Scuba recommends using the Poppet Align/
Orifice Preset Tool (P/N 20-785-400), available from
Peter Built Co. (See Fig. 10.)
