handle will stay in the unlocked position
until it is manually disengaged from the
guide plate. See
Fig. 17.12.
2.2
Holland: Pull the operating rod out. Make
sure both side plungers have released.
See
Fig. 17.13.
3.
Lower the trailer landing gear just enough to re-
move the weight from the vehicle.
4.
Chock the front and rear trailer tires to prevent
the trailer from moving.
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 vehicle 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.
5.
Release the vehicle parking brake, then slowly
move the vehicle forward or backward until the
fifth wheel is in the desired location.
WARNING
Check that the locking wedges have seated in the
slots. Failure to achieve complete lockup may
allow disengagement of the tractor from the
trailer, possibly resulting in serious personal in-
jury or death.
6.
Apply the vehicle parking brake, then lock the
sliding member in position using one of the fol-
lowing methods:
6.1
Fontaine: Disengage the slide release
pull handle from the guide plate. The slide
release pull handle is spring-loaded in the
locked position and will seek the locked
position when disengaged from the guide
plate. After the slide release pull handle
returns to the fully locked position, visually
and physically check the locking wedges
to make sure they are fully inserted into
the slots in the slide rails. Make sure the
handle is locked in position against the
guide plate.
6.2
Holland: Raise the operating rod so that it
is free to move inward. Make sure that the
lock pins have seated in the base plate
rail holes and the operating rod moves
into the locked position.
NOTE: The fifth wheel may need to be moved
slightly to enable the locking wedges to enter
the fully locked position.
