8. Lift out the diaphragm(4) and thrust washer(3) from the
second stage housing. Inspect the diaphragm to ensure
that it is supple and free of any pinholes, tears, corrosion,
or other damage. If any damage is found, discard it and
replace with new.
9. Using a small regular screwdriver, rotate the metal
retaining clip(5) over the groove of the venturi
deflector(22) as needed so that the notch in the center
is visible. Place the tip of a 2mm flat blade screwdriver
inside this notch, and gently lift the clip off the groove.
(See Fig. 1.)
10. Apply a medium blade screwdriver to the screw(24) in
the center of the venturi deflector switch(23), and turn
it counter-clockwise to loosen and remove. Pull off the
deflector switch and set it aside.
11. While holding the lever(6) lightly depressed, slide the
entire valve assembly out of the second stage housing,
venturi deflector first (see Fig. 2). Remove and discard
the inlet fitting O-ring(8).
12. Unscrew the venturi deflector counter-clockwise from the
air barrel(15), and carefully remove the O-ring(21) with a
plastic tool.
13. Turn the air barrel over to allow the balance shuttle
cap(20) and LP spring(19) to drop out (see Fig. 3).
Inspect the spring closely with a magnifier to check for
any signs of corrosion. Discard it if corrosion is found,
and do not reuse.
14. Gently remove the lever from the air barrel by lifting out
one leg first, and then the other. Be careful to avoid
bending or stretching either leg.
15. Turn the air barrel over to allow the poppet(17) to drop
out. Using fingernails or a plastic tool, carefully remove
the LP seat(16) and small O-ring(18). Discard both soft
parts, and do not reuse. Closely inspect the poppet
around all seating surfaces, and compare it with new to
ensure no damage is visible. If damage is found, discard
the poppet and replace with new.
16. Remove the white lever pad(14) from the air barrel.
Discard, and do not reuse.
17. While holding the air barrel secure, apply a medium
blade screwdriver to the slotted head of the adjustable
orifice(9), and turn it counter-clockwise to disengage its
threads.
