Driver's Manual
NOTICE
Ensure the trailer landing gear does not come in
contact with the tractor frame or other compo-
nents, and that the front of the trailer will not
come in contact with the rear of the cab or other
components if they extend beyond the rear of the
cab.
5.
Apply the tractor parking brakes.
WARNING
Check that the locking wedges have seated in the
slots. Failure to achieve complete lockup may
allow disengagement of the tractor from the
trailer, possibly resulting in serious personal in-
jury or death.
6.
Set the air-slide switch to LOCK. Visually inspect
the locking wedges or plungers to make sure
that they are fully inserted in the slide rail slots.
Verify that the plungers have engaged by tugging
the tractor forward while the trailer brakes are
locked and the tires are chocked.
NOTE: The fifth wheel may need to be moved
slightly to enable the locking wedges to fully
lock.
