TM 10-4930-245-13&P
2-2. LOCATION AND USE OF CONTROL AND INDICATORS.
CAUTION
Never attempt to tighten or loosen the poppet unless the diaphragm assembly is securely held in
place by tool diaphragm wrench part number 220282. Failure to use this tool will cause damage
to the diaphragm making the nozzle unusable.
CAUTION
Never operate the flow actuating handle unless the diaphragm is wetted by fuel. Actuation of
this handle when the diaphragm is dry may greatly damage the diaphragm making the nozzle
unusable.
CAUTION. Never use a screwdriver or sharp object to push the staybacks. Failure to heed this
warning will result in damage to the collar causing binding. This will make the CCR nozzle non-
operational.
CAUTION
Never defuel system without first isolating the CCR nozzle beforehand. Damage to the
diaphragm may result making the nozzle unusable.
CAUTION
Never let the internal spring force slam the handle open because this may fracture the latch.
CAUTION
Never allow trapped fuel to remain in the CCR nozzles after use because damage results from
increased internal pressure. Drain a substantial portion of the trapped fuel from all nozzles fitted
with inlet valve fittings. This action should be taken immediately upon removing nozzle from the
system.
