REGUlAR OPERATIONAl INSPECTION CONTINUED...
REGULATOR INSPECTION
Inspect the breathing regulator for damaged or missing components.
1. Verify that the regulator gasket is not damaged and is in place around
the outlet port of the regulator.
2. Verify that the purge valve (red knob) is not damaged and turns
smoothly one-half turn from stop to stop.
3. Inspect the Heads-Up Display for damage. Verify that the rubber
guard is in place and is not torn or damaged.
4. If the hose to the breathing regulator is equipped with a quick dis-
connect, inspect both the male and female quick disconnects. Pay
special attention to the following:
a) Inspect the operation of the locking sleeve on the female quick
disconnect. If any damage is noted, remove it from service and
tag for repair.
b) Inspect the condition of the male quick disconnect for signs of
wear. Particularly look for wear on the locking ridge as shown in
FIGURE 4. If the coating is worn through and bare metal is show-
ing, do not use the regulator assembly. Remove it from service
and tag for replacement.

Coupling. See FIGURE 5. Refer to the following instructions and
illustrations:

Pull-back Sleeve Quick Disconnect
a) While pushing the plug "D" into the socket, pull the locking sleeve
"E" back toward the guard. The plug "D" will separate.
b) To reconnect, align the HEADS-UP DISPLAY plug with the mating
connector. A collar on the female coupling prevents misalign-
ment of the connectors. Push plug "D" into the socket until the
locking sleeve "E" pops forward. Test for proper engagement by
tugging on the coupling.
