1. Position tractor and trailer in a straight line on level ground.
2. Lock the trailer brakes.
The trailer must be stopped and the trailer brakes
locked to prevent damage to the tractor or trailer
by uncontrolled sliding of the fifth wheel.
3. Release slide locking
plungers.
4. Visually check that both
plungers are fully extended,
as shown in Figure 4A.
NOTE: If the plungers do not
release, using low gear on the
landing gear, raise the trailer
to relieve pressure on the
plungers. This will allow the
fifth wheel to slide easier.
5. Slowly drive the tractor forward or backward to position
the fifth wheel.
6. Re-engage the slide
locking plungers.
Verify that both
plungers have fully
engaged.
NOTE: Retract landing
gear if lowered.
