Quick-Fill And Urc Coupling Inspection - Firehawk M7XT Operación E Instrucciones

QUICK-FILL AND URC COUPLING INSPECTION

DO NOT disconnect the Audi-Larm Alarm coupling nut when
pressure is shown on analog pressure gauge. Release all
pressure from the air mask by opening the Firehawk
Regulator bypass valve. Removing the coupling nut with the
air mask is pressurized can result in serious personal injury,
death, or damage to equipment.
QUICK-FILL AND URC COUPLING INSPECTION
Inspect the URC and Quick-Fill coupling for tightness of the
coupling halves and tightness of the coupling to the air mask.
Perform both inspections simultaneously.
1. Close the cylinder valve and relieve system pressure. (See
DISCONNECTING THE FIREHAWK PUSH-TO-CONNECT
REGULATOR or DISCONNECTING THE SLIDE-TO-CON-
NECT FIREHAWK REGULATOR for instructions).
2. Use a fine-tip ink marker
and a ruler or straight
edge to draw a line on
the male coupling. Make
sure the line extends
across the joint and cou-
pling hex flats onto the
Audi-Larm or Quick-Fill
manifold body.
3. Put the dust cover on the coupling.

WARNING
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 coupling is
sufficiently tight and the
air mask may be returned
to service.
