Failure to couple with
the trailer at the proper
height could result in
improper coupling,
allowing tractor-trailer
separation which, if not
avoided, could result in
death or serious injury.

suspension when the
kingpin is above the
throat of the fifth wheel.
Failure to avoid inflating
the tractor suspension
when the fifth wheel
is NOT forward of the
kingpin, could result in
damage to the kingpin
and fifth wheel.

the kingpin into the fifth wheel.
11. Connect the air and electrical lines.
12. Raise the landing gear legs until the
pads are just above the ground.
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 12)
.
14. Place the tractor into neutral and set
the parking brake.

the following to ensure that the lock
is closed.
a. Nut and washer MUST be snug against

trailer upper coupler plate and the
fifth wheel
(Figure 14)
.
