2-10. ASSEMBLY AND PREPARATION FOR USE - cont.
f.
Non-Valved Dry Break Coupling Assembly. Refer to figure 2-9.
CAUTION
To prevent damage to the equipment and contamination of the fuel system, use
care when connecting couplings to avoid getting dirt, sand and debris on coupling
mating surfaces and sealing components. Do not remove dust caps from
couplings until components are ready to be connected.
NOTES
·
All dry break type couplings are interchangeable. A valved dry break coupling
may be connected to either a valved or non-valved dry break coupling.
·
The following instructions apply to all operator tasks requiring connection of
non-valved dry break couplings. One coupling is shown. The others are
similar.
(1)
Twist dust cap (1) to the left and disconnect from coupling (2).
(2)
Twist dust cap (3) to the left and disconnect from coupling (4).
NOTE
One locking lug is larger than the other. Both locking lugs match a socket in the
mating coupling.
(3)
Mate locking lugs (5) on coupling (4) with sockets (6) in body of coupling (4).
(4)
Twist couplings (5 and 6) to the right (clockwise) until both couplings lock together.
CAUTION
If couplings can be separated, couplings are not connected correctly.
(5)
Twist couplings (5 and 6) to the left (counterclockwise) and test security of connection.
CAUTION
To prevent dust, grit and sand from contaminating couplings, connect caps
together after couplings are joined.
(6)
Connect dust cap (1) to dust cap (3).
