GENERAL PRINCIPLES OF OPERATION
The D1N-1 or D-1R Nozzle mates with the aircraft adapter for fuel servicing. The clip and plug ground cable
connections provide for grounding and bonding the nozzle to the aircraft prior to connection and during servicing. ne
nozzle must align with the aircraft adapter before nozzle collar is turned and secured. The poppet handle assembly can
now be turned to the open position. The nozzle assembly is now firmly attached and cannot be removed. After servicing
is complete, the poppet handle assembly is returned to the closed position and the collar turned releasing the nozzle from
the aircraft. The collar also prevents the poppet handle from being turned to the open.
