EXHAUST SUSPENSION AIR
BEFORE BACKING UP
4. Set tractor parking brake and place
into neutral.
5. Completely exhaust air from tractor
suspension, ensuring that the fifth
wheel is below the contact surface
of trailer (Figure 9).
6. Exit the cab and make sure the fifth
wheel is below the upper coupler plate.
Verify proper fifth wheel height. If
trailer is too low, use landing gear to
raise the trailer height.
NOTE: For proper operation of landing
gear, follow the instructions
published by the landing
gear manufacturer.
7. Slowly back up, using lowest gear
possible. Stop when fifth wheel is
under the leading edge of the trailer
(Figure 10).
8. Set tractor parking brake. Place in
neutral. Exit cab and verify proper fifth
wheel to kingpin alignment.
9. Adjust tractor suspension to ride height.
The fifth wheel plate face MUST make
contact with the upper coupler plate
(Figure 11). If fifth wheel does not
make contact with the upper coupler
plate, use the landing gear to lower the
trailer until fifth wheel makes contact.
IMPORTANT: If trailer is too high the
kingpin will not properly
connect with the lock jaw.
Failure to couple with the
trailer at the proper height
could result in improper
coupling, allowing tractor
and trailer separation,
which if not avoided,
could result in death or
serious injury.
