until it is manually disengaged from the
guide plate. See

sure both side plungers have released.

prevent the trailer from moving.

move the tractor forward or backward until the
fifth wheel is in the desired location.
NOTICE
When moving the fifth wheel to the desired posi-
tion, be sure the trailer landing gear will not at
any time come in contact with the tractor frame
or other components. Make sure that the front of
the trailer will not come in contact with the rear
of the cab or with other components if they ex-
tend beyond the rear of the cab.
