Hookup/Coupling and Uncoupling
Never operate a tractor/trailer combination that is
not properly coupled.
Inspect the trailer coupler and kingpin for damage,
cracking, excessive corrosion, and wear.
Position the tractor directly in front of the trailer,
never back under the trailer at an angle. This can
result in damaged landing gear.

Adjust the trailer height so that the trailer contacts
the fifth wheel approximately 6" behind the pivot.
IMPORTANT! When coupling, you must lift the
trailer to ensure proper engagement of the kingpin
to the fifth wheel.
Back up the trailer carefully, slowing to a near stop
until the fifth wheel locks.
Pull forward in low gear to test the coupling. This
initial check also confirms the trailer parking brakes
are applied.
WaRNING:
Never operate a trailer without first visually
inspecting and verifying a proper coupling.
a visual inspection is required by law. Some
improper couplings can pass a pull test. Sound
alone is not reliable. a visual inspection is
mandatory.
