Operation Instructions
13. Perform a pull test as an INITIAL CHECK
by locking the trailer brakes and pulling
forward with the tractor to ensure that
tractor-trailer separation DOES NOT
occur
(Figure 15)
.
14. Place the tractor into neutral and set
the parking brake.
15. Exit the cab and visually inspect for
the following to ensure that the lock
is closed:
a. Nut and washer MUST be snug
against the fifth wheel
(Figure 16)
.
b. No gap is permissible between the
trailer upper coupler plate and the
fifth wheel
(Figure 17)
.
c. Fifth wheel locks MUST be closed
around the trailer kingpin with 1/4"
(6.35 mm) or less gap visible between
the lock jaws
(Figure 18)
.
16. If proper coupling has NOT been
achieved, repeat the coupling procedure.
Failure to properly couple
the tractor and trailer could
result in tractor-trailer
separation while in use
which, if not avoided,
could result in death or
serious injury.
IMPORTANT:
DO NOT use any fifth
wheel that fails to
operate properly.
Failure to repair a
malfunctioning fifth
wheel before use could
result in tractor-trailer
separation which, if not
avoided, could result in
death or serious injury.
