Inspection of the mask-mounted regulator includes checking the regulator gasket, purge valve, Heads-Up Display
(HUD), regulator hose, and quick-disconnect.
To inspect the regulator

.
2 Verify that the regulator gasket is not damaged and is in place around the outlet port of the regulator. See

3 Inspect the HUD for damage. Verify that the rubber guard is in place and is not torn or damaged.
4 If the hose to the mask-mounted regulator is equipped with a quick-disconnect, 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 it for repair.
b Inspect the condition of the male quick-disconnect. Look for
signs of wear on the locking ridge as shown in
Figure 1-6 Inspecting the male quick-disconnect
CAUTION
Do not use tools to open or close the purge valve. Using tools to open or close the purge valve may result in
damage to the valve. Instead, open or close the valve using finger pressure only. Rotation of the purge valve
is limited to one-half turn.
