7. Slowly back up, using the lowest gear
possible. Stop when the fifth wheel is
under the leading edge of the trailer
(Figure 13)
.
8. Place the tractor into neutral and set the
parking brake. Exit the cab and verify
proper fifth wheel-to-kingpin alignment.
9. Adjust the tractor suspension to ride
height. The fifth wheel top plate face
MUST make contact with the upper
coupler plate
(Figure 14)
. If the fifth
wheel DOES NOT make contact with
the upper coupler plate, use the landing
gear to lower the trailer until the fifth
wheel makes contact.
IMPORTANT:
If the trailer is too high,
the kingpin will NOT
properly connect with
the lock jaws.
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.
IMPORTANT:
NEVER inflate the tractor
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
king pin, could result in
damage to the kingpin and
fifth wheel.
10. Slowly back into the trailer, engaging
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.
