4.2.3 With the Razor Valve/Regulator still installed tightly in the cylinder (AND ALL AIR BLED FROM THE
CYLINDER), use a 10” or 15” adjustable wrench to loosen (not remove) the Cap (2) from the Body (14).
4.2.4 Use a 3/16” Allen wrench to remove all port plugs from the body. Discard the port plug O-rings. (10,
18)
4.2.5 Use the 6” adjustable wrench to loosen and remove the male Quick Disconnect probe (31) from the
body. When removing probe, be careful not to lose the Spring (28) or Check Valve Plug (29). Discard the
Probe and Plug O-rings (18, 30, 32)
4.2.6 Turn the Valve Handwheel (25) so the Valve is about 1/2 way between open and closed. Use a 5/32”
Allen wrench to remove the Nut (27) from the Valve. Remove the Spring (26), Handwheel (25), and Washer
(24) from the Stem (21).
4.2.7 Use the 6” adjustable wrench too loosen and remove the Bonnet Nut (23). Remove the Stem (21)
from the Bonnet Nut and use it as a tool to turn the Plug Assembly (20) out of the body. (See Photo 1)

If the Valve was not turned 1/2 way between open and closed as described in step 4.2.6, you may need to
install the Handwheel (25) temporarily back on the Stem to turn the Plug Assembly out with more force.
4.2.8 Remove and discard the O-ring (18) and Seal (22) from the Bonnet Nut (23).
4.2.9 Unscrew the Burst Plug (11) that was previously loosened in step 4.2.1. Tip the tank and body so that
the Burst Disc (12) and Gasket (13) fall out. If the Gasket (13) does not fall out when the body is tipped,
you may need to pry it out with a soft brass pick. Be EXTREMELY careful and do not scratch the surface
under the gasket, since a scratch on the body at the gasket area will create a leak. The gasket can be
reused once or twice. If you are going to reuse it and it does not fall out easily, leave it in place when the
reg is cleaned. Check that it is still in place during assembly.
4.2.10 At this point, all of the ports on the body should be empty.
