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
injury 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.
The fifth wheel may need to be moved slightly to
enable the locking wedges to fully lock.
Further verify that the plungers have engaged by
tugging the tractor forward while the trailer
brakes are locked and the wheels are chocked.
