Operation Instructions
3. Tilt ramps of fifth wheel downward
(Figure 5).
4. Make sure locks are open. If locks
are closed:
a. Manual Release: If equipped with
a manual secondary lock, first pull
secondary release handle and hook on
casting (Figure 6). Pull the release
handle completely out (Figure 7).
b. Air Release: Set the tractor parking
brake and pull the fifth wheel release
valve until locking mechanism opens
and locks in place. Release the pull
valve. Release the tractor parking brake.
5. Visually inspect fifth wheel throat to
ensure locks are completely open and
ready to accept kingpin (Figure 7).
6. If locks are not completely open
(Figure 7), check the following:
a. Nut and washer at front of fifth wheel
are not snug against the wheel.
b. Release handle is in extended
“open” position.
If both of these conditions exist, you will
still be able to couple the fifth wheel
even though the lock jaws appear closed.
The movement of the kingpin into the
fifth wheel jaws will allow them to open
and successfully couple.
If either above conditions do not exist,
repeat Steps 4 - 6.
7. Coupling Procedures
1. Chock trailer wheels.
2. Position the tractor so the center of the
fifth wheel is aligned with the kingpin.
3. Traveling in a straight line, slowly back
tractor to trailer. STOP the tractor before
making contact with the trailer
(Figure 8).
