Coupling Procedures for Over-The Road Use
For private yard operation (yard-spotter) coupling instructions, proceed to page 9. The
two steps below are required for operation of this fifth wheel on public streets.

ROD VISIBLE
HANDLE IS IN
1. Unhook and engage the secondary lock for operation on public streets.
IMPORTANT: This unit is not intended for operation on public streets and
highways with the fifth wheel in the up position. Do not operate
this unit on public highways unless the fifth wheel manual
secondary lock is engaged. The fifth wheel must be in the full
down position and the lockdown pins (option -87) fully engaged.
2. Place the fifth wheel in the full down position and engage the top plate lock
down pins.
NOTE: The fifth wheel must be fully lowered to allow the lockdown pins to
engage. If the wheel is up too high, put the transmission in neutral and
engage the power take off (PTO). Set the engine speed to 1,000 to 1,200
r.p.m. and operate the control valve to lower the trailer and fifth wheel
until they are all the way down.
To engage the pins, move the handle from the “Yard Use” position (handle
pointing toward the front of the tractor), to the “Highway Use” position (handle
pointing toward the rear of the tractor) as shown below. This operation is also
illustrated on the instruction label located directly above the handle on the left
front side of the fifth wheel frame assembly.

Failure to lower fifth wheel to full down position and engage
lockdown pins prior to moving a coupled tractor will increase vehicle
instability which, if not avoided, could result in serious injury or death.
