8. Uncoupling Procedures
1. Position the tractor and trailer, in straight
alignment, on firm, level ground clear
of obstacles and persons.
2. Set the trailer brakes.
3. Slowly back the tractor tightly against
the trailer to relieve pressure on the
fifth wheel locks.
4. Place the tractor into neutral and set
the parking brake.
IMPORTANT:
DO NOT exhaust air from
the tractor suspension
before uncoupling.
Failure to avoid exhausting
air from the tractor
suspension before
uncoupling could result in
difficulty uncoupling the
tractor from the trailer
which, if not avoided, could
result in damage to the
fifth wheel and kingpin.
5. Chock the trailer wheels.
6. Lower the landing gear until the pads
just touch the ground
(Figure 17)
.
NOTE:
For proper operation and ability
to transfer the trailer weight
from the fifth wheel, follow the
instructions published by the
landing gear manufacturer. DO
NOT raise the trailer off of the
fifth wheel.
7. Disconnect the air and electrical lines
from the trailer and secure to the tractor.
8. If equipped, pull the secondary lock
release handle and hook on the top
plate casting
(Figure 18)
.
