condition. Check the air cylinder and oth-
er hardware of the air pressure assembly
for loose connections. Check that the
high pressure rupture disk assembly (15,
pressure) (5) are not blown out. Inspect
the frame and harness assembly (fig. 1-2)

straps and the air cylinder strap fasten the
agent container and the air cylinder to the
frame. Make sure that the spring loaded
clamps are fully closed. Verify that
shoulder straps and waist strap are in ser-
viceable condition, free of excessive wear,
and that no slide buckles are missing or
broken. Inspect the frame for damage or
missing identification (fig. 1-6). Check
that screws and nuts securely fasten the
pressure regulator to the frame. If inspec-
tion reveals deficiencies in the frame and
harness assembly, notify organizational
maintenance personnel.

GUN ASSEMBLY
Inspect the disperser to determine that the
nozzle is installed. If the disperser is being
used with CS dry agent, the jet spray unit
must be installed on the gun. If the dis-
perser is being used with CR liquid agent,
the multijet spray unit (fig. 1-1) must be
installed on the gun. Turn the grip knob
(1, fig. 1-4) clockwise until resistance is
felt (approximately I full turn) to make
sure that the high-pressure air is shut off.
Make sure that hole in jet spray unit is not
plugged.
