Aircraft Overwing/Closed Circuit Fuel Dispensing
Operation.
The overwing fuel dispensing operation is used
to fuel winged aircraft through a fill port on top of aircraft
wings. The closed circuit fuel dispensing operation is used
to fuel helicopters. Fuel is pumped through the filter/se-
parator, a meter, and a hose reel to the aircraft or helicop-
ter (fig. 2-38). Fuel dispensing operation is as follows:
(1) Review instructions in paragraph 2-8.
WARNING

hands when opening and closing. Use
latches to lock door. Do not slam.
(2) Open hose reel cabinet door. Pull release
cable and lift door with both hands.
(3) Ensure that all valves are closed.
(4) Unreel the static reel cable and connect first
to grounding stud and then to aircraft.
(5) Remove fire extinguishers and bring to point
of operation.
(6) Start engine (para 2-10) and when warm
adjust engine speed to 1000–1200 rpm.
(7) Open valves A (para 2-11f), H, M, and P.
Reset the meter to zero by pushing the meter reset knob
