Operation Instructions
8. Slowly back tractor just past the
leading edge of the trailer so that fifth
wheel is under trailer (Figure 12).
9. Adjust tractor suspension to ride
height. Fifth wheel plate face must
make contact with bolster plate
(Figure 13).
Failure to couple with the
trailer at the proper height
may result in improper
coupling, allowing tractor
and trailer separation,
which if not avoided, could
result in death or serious
injury.
10. Slowly back into trailer, engaging
kingpin in fifth wheel.
11. Perform a pull test as an INITIAL
CHECK by locking trailer brakes and
pulling forward with tractor to make
sure tractor trailer separation does
not occur (Figure 14).
12. Get out of tractor and visually inspect
the following to be sure lock is closed
and tractor and trailer are properly
coupled (Figure 15).
a. Nut and washer must be snug
against the fifth wheel casting.
b. No gap is permissible between
trailer bolster plate and fifth
wheel.
c. Fifth wheel locks must be closed
around the trailer kingpin with
1/4” or less gap visible between
the lock jaws.
