QUICK-FILL AND URC COUPLING INSPECTION
3. Put the dust cover on the coupling.
4
. Grasp the dust cover by hand and, using maximum
effort, attempt to loosen the coupling at the joint by
turning the dust cover counterclockwise. Do not use
tools.
5. If the line does not line
up across the joint...
...or across the joint
where the coupling
attaches to the air
mask, remove the air
mask from service until
a replacement coupling
is installed. If the line
does line up, the cou-
pling is sufficiently tight
and the air mask may
be returned to service.
