WARNING
Bonding of the semitrailer to aircraft and
grounding procedures as in paragraph 2-8b
while refueling shall be mandatory, regard-
less of the amount of fuel to be dispensed,
due to the dangers of static electricity. Bond
the fuel nozzle ground wire to the aircraft be-
fore bringing nozzle In contact with the air-
craft.
(6) Unreel static reel cable and connect it first to
grounding stud, then to aircraft.
(7) Release lock (para 2-11) on the 1½-inch hose
reel, and unreel all hose. Remove the dust cap from the
bottom load adapter and connect converter to the
adapter.
(8) Remove dust cap from inlet C and connect
defueling hose to inlet. Next connect the defueling hose
ground wire to the aircraft, then connect the hose.
NOTE
Make sure valve E is closed and remains
closed during entire operation.
(9) Open valves A (para 2-11f), G, M, and P
Reset the meter to zero by pushing in reset knob (fig. 2-15)
and turning clockwise.
NOTE
If 2½-inch hose was used before using
1½-inch, depress and hold deadman release
plunger in the hose reel cabinet (fig. 2-15) for
5-10 seconds to deactivate the deadman
system. If this procedure Is not followed, no
fuel will flow to 1½-inch hose.
(10) Set engine throttle at desired flow rate
(table 2-2). Squeeze trigger on overwing nozzle.
WARNING
When filling tank by means of defueling, a test
of the precheck system is mandatory. If this
system Is not functioning, stop all operations.
Determine the problem and have It corrected
by a qualified technician. Failure of automatic
shut-off to function may result in uncontrolled
fuel spillage and danger of fire and explosion.
(11) Shortly after flow has begun, turn precheck
valve D to the OPEN position to precheck the automatic
shut-off float. If float is functional, flow should stop after
about 20-25 seconds (para 2-11g).

overwing nozzle,
and adjust engine to idle speed
(1000-1200 rpm).
(14) Remove the defueling hose from aircraft
first, then remove the hose ground wire. Disconnect the
defueling hose from inlet C. Replace the dust cap to
outlet C.
WARNING
DO NOT let go of the static reel cable when
rewinding until the ball stop is firmly touching
the reel. Failure to follow this warning may
cause injury to personnel.
(15) Disconnect the ground connection first from
the aircraft, then from the grounding stud. Rewind the
static reel cable.
