2-15.
PREPARATION FOR MOVEMENT- cont.
(2)
Disconnect ground cable from aircraft.
(3)
Lift slide (3) forcefully against upper stop collar (4). Repeat until ground rod (2) is pulled from soil.
(4)
Repeat steps (1), (2) and (3) for three remaining ground rods.
b.
Non-Valved Dry Break Coupling Disconnection. Refer to figure 2-18.
CAUTION
To prevent damage to the equipment and contamination of fuel system
components, use care when disconnecting couplings to avoid getting dirt, sand
and debris on coupling mating and sealing components. Install dust caps on all
open couplings.
NOTE
The following instructions apply to all operator tasks requiring disconnection of
non-valved dry break couplings. One coupling is shown. The others are similar.
(1)
Turn dust cap (1) to the left and separate from dust cap (3).
(2)
While pulling back on ring (7), turn coupling (2) to the left (counterclockwise) and disconnect from coupling
(4).
(3)
Position dust cap (3) on coupling (4). Turn dust cap to the right to secure cap to coupling.
(4)
Position dust cap (1) on coupling (2). Turn dust cap to the right to secure cap to coupling.
c.
Valved Dry Break Coupling Disconnection. Refer to figure 2-19.
CAUTION
To prevent damage to the equipment and contamination of fuel system
components, use care when disconnecting couplings to avoid getting dirt, sand
and debris on coupling mating and sealing components. Install dust caps on all
open couplings.
NOTE
The following instructions apply to all operator tasks requiring disconnection of
valved dry break couplings. One coupling is shown. The others are similar.
(1)
Turn dust cap (3) to the left and separate from dust cap (5).
(2)
Pull back on grip (1) and set control arm (2) to CLOSE position.
(3)
While holding coupling (6) in place, turn coupling (4) to the left (counterclockwise) until couplings
disconnect.
(4)
Position dust cap (5) on coupling (6). Turn dust cap to the right to secure cap to coupling.
(5)
Position dust cap (3) on coupling (4). Turn dust cap to the right to secure cap to coupling.
