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 tractor parking brakes, 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.
Air Slide Operation
The slide feature may be operated with an air switch
mounted in the dash, that operates an air cylinder
that locks and unlocks the slide. See
Fig. 20.14 .
1. Set the air-slide switch ( Fig. 20.14 ) to SLIDE.
Ensure the locking plungers have released. See
Fig. 20.15 .
For Jost fifth wheels, the mechanism activates as
shown in
Fig. 20.16 .
2. Lower the trailer landing gear just enough to re-
move the weight from the tractor.
3. Pull the red trailer-air-supply knob to set the
trailer-parking brakes.
4.
Slowly move the tractor forward or backward
until the fifth wheel is in the desired location.
NOTICE
Ensure the trailer landing gear does not come in
contact with the tractor frame or other compo-
nents, and that the front of the trailer will not
come in contact with the rear of the cab or other
components if they extend beyond the rear of the
cab.
5.
Apply the tractor parking brakes.
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.
