Operation Instructions
13. Perform a pull test as an INITIAL CHECK
by locking the trailer brakes and pulling
forward with the tractor to make sure
that tractor-trailer separation does not
occur (Figure 15).
14. Set the tractor parking brake.
15. Exit the cab and visually inspect for
the following to ensure that the lock
is closed (Figure 16).
a. Release handle fully retracted with
lock notch behind rib.
b. No gap is permissible between the
trailer upper coupler plate and the
fifth wheel.
c. Lock securely closed behind jaw.
16. If proper coupling has NOT been achieved,
repeat the coupling procedure.
Failure to properly couple
the tractor and trailer could
result in tractor-trailer
separation while in use
which, if not avoided,
could result in death or
serious injury.
IMPORTANT: DO NOT use any fifth
wheel that fails to
operate properly.
Failure to repair a
malfunctioning fifth
wheel before use could
result in tractor-trailer
separation which, if not
avoided, could result in
death or serious injury.
17. Fully retract the landing gear legs
off the ground and secure the crank
handle (Figure 17).
NOTE: For proper operation of landing
gear, follow the instructions
published by the landing
gear manufacturer.
18. Remove the wheel chocks and continue
with the pre-trip inspection.
