fore making contact of nozzle to vehi-
cle.
a. Insert ground plug (17, fig. l-l) into vehicle,
and/or attach alligator clip (6) to unpainted metal
surface on the vehicle. Do not attach to propeller or
radio antenna. Nozzle and vehicle are now bonded
and grounded.
b. Make certain handle (4) is latched in the down
position. If handle is left in up (flow) position, it
may be difficult to make connection to gravity fill
adapter due to line pressure in nozzle.
c. Attach gravity fill adapter (3) to nozzle as-
sembly with a straight push motion. A positive con-
nection is indicated by the actuating ring moving
forward with an audible click.
d. Unlatch nozzle handle (4) and place in up pos-
ition. Remove vehicle fuel tank cap and adapter
dust cap and insert gravity fill adapter spout into
vehicle fuel tank. Start fueling by squeezing trigger
(9) of gravity fill adapter.
NOTE
Completion of fill is not controlled automatically by
shutoff valves in vehicle. The trigger of the gravity
fill adapter will allow metering flow rate to obtain
proper fuel level. Visually check fuel level in tank
of vehicle. Do not overfill.
e. Release gravity fill adapter trigger. Allow suf-
ficient time for fuel to drain from spout before re-
moving from vehicle. Replace cap on vehicle fuel
tank and cap adapter. Disconnect ground clip or
f.
plug.
Return nozzle assembly handle to the down
(no-flow) position. When fueling operations are fin-
ished for the day, disconnect gravity fill adapter
from nozzle by pulling actuating ring cable loop (15,
fig. 1-1), Replace dust plug (8) in coupling end of
nozzle assembly. Install dust caps (10) on gravity
fill adapter.
Section II.
OPERATION UNDER UNUSUAL CONDITIONS
2-4. Operation in Extreme Cold
The closed-circuit refueling nozzle assembly will
operate satisfactorily in temperatures down to -
25°F. (-32°C.). Protect the nozzle from ice and
snow.
245. Operation in Extreme Heat
The closed-circuit refueling nozzle assembly will
operate satisfactorily in temperatures up to 125°F.
(52°C.) when ordinary precautions are taken.
2-6. Operation in Dusty or Sandy
Areas
The closed-circuit refueling nozzle assembly is
affected by dusty or sandy conditions. The gravity
fill adapter spout should be cleaned immediately be-
fore starting refueling operations. Keep all dust
caps in place.
2-7. Operation Under Rainy or Humid
Conditions
Keep gravity fill adapter spout capped except
when in use. Dry nozzles thoroughly before re-
fueling vehicles and aircraft.
2-8. Operation in Salt Water Areas
Operation in salt water areas presents corrosion
problems. Keep exposed metal parts clean by wash-
ing with fresh water and drying thoroughly.
2-9. Operation at High Altitudes
Operation of the closed-circuit refueling nozzle
assembly is not affected by altitude.
