WARNING
Ensure that all fifth wheel mainte-
nance, adjustments, and rebuilding are
done
only by a qualified mechanic. An
improperly maintained fifth wheel can
cause a trailer to separate from a trac-
tor. This could lead to a serious acci-
dent. Failure to comply may result in
property damage, personal injury, or
death.
Your vehicle is equipped with either a
Fixed or an Air-Controlled Sliding Fifth
Wheel. Either type should self lock when a
trailer king pin trips the locking dogs as the
tractor is backed under a trailer
.
How to Lock the Kingpin
Ensure that the fifth wheel lock is in the
unlocked position.
WARNING
Always inspect the fifth wheel for prop-
er
locking after coupling the tractor to
a trailer. Failure to properly couple the
tractor to a trailer (the kingpin is en-
gaged
in a closed lock jaw with the
lock jaw secured by a closed plunger)
may cause trailer separation which
could result in an accident involving
death or personal injury.
To lock the fifth wheel around the kingpin:
1.
Ensure trailer brakes are locked
and the landing gear is down.
2. Back the tractor fifth wheel into the
trailer kingpin to engage and lock.
JOST Fifth Wheel Indication
If equipped with JOST fifth wheel
3.
Pull the tractor forward to ensure
the kingpin has been locked in
place.
4. Set the tractor parking brake.
5. Connect the tractor brake air and
electric lines to the trailer.
Conduct a pre-trip inspection prior to
releasing the brakes, raising the landing
gear, and driving the vehicle.
How to Release the Kingpin
Remotely (option)
CAUTION
Do not deflate the rear suspension be-
fore
unlocking the fifth wheel. Deflating
the rear suspension before unlocking
the fifth wheel could cause difficulty
during uncoupling and result in dam-
age to the fifth wheel and kingpin.
1. Set both the vehicle and trailer
parking brakes.
2.
Lower the landing gear.
3. Disconnect the tractor brake air
and electric lines from the trailer.
4. Flip up cover, then press and hold
the Kingpin Release switch for 3
seconds. A countdown timer popup
will appear on the display, and the
unlock symbol on the Kingpin
Release switch will illuminate.
