Operation Instructions
11. Completely exhaust air from tractor
suspension, ensuring that fifth wheel
is below the contact surface of trailer
(Figure 21
) .
12. Slowly pull away from trailer.
13. Air-up tractor air suspension to ride
height (Figure 22).
8. Positioning Sliding
Fifth Wheels
1. Position tractor and trailer in a
straight line on level ground.
2. Lock trailer brakes.
Failure to stop and
properly lock the trailer
brakes may cause
uncontrolled sliding of fifth
wheel which, if not
avoided, may result in
component damage to
tractor or trailer.
3. Release slide locking plungers by
moving cab switch to unlock position
(Figure 23). (If manual slide release
equipped, pull release lever.) If
plungers do not come out, lower the
landing gear to relieve pressure on
the fifth wheel. This will allow fifth
wheel to slide easier.
4. Slowly drive the tractor forward or
backward to position fifth wheel and
stop tractor at desired position.
5. Re-engage slide locking plungers by
moving cab switch to the lock position
(Figure 24). (If manual slide release
equipped, trip release arm to allow
plungers to retract.).
NOTE: Cab switch style may differ by OEM
design.
