2. Visually check that the release lever is engaged
(locked).
3. Attempt to pull forward as an initial test of the locking
of the release lever.
raise the Drop-leg Jack
A trailer having a fifth wheel kingpin will be outfitted with one
or two drop leg jacks to support the trailer. Because we use
several drop leg jack mechanisms, the general instructions
below may vary slightly from the jack manufacturer’s
instructions.
1. Rotate the jack handle counterclockwise (Figure 13).
This will slowly retract the jack and transfer the weight
of the trailer to the towing vehicle. Continue retracting
the jack to its fully-retracted position.

Breakaway Brake system
If the kingpin gets disconnected, a properly connected
and working breakaway brake system will apply brakes
on the trailer.

uncoupling Fifth-wheel
Follow these steps to uncouple fifth wheel kingpin from
the tow vehicle:
1. Block trailer tires to prevent the trailer from rolling.
2. Make certain that ground surface below the jack base
will support trailer load.
3. Rotate the handle (or crank) clockwise to slowly extend
the jack to the ground and transfer the weight of the
trailer to the jack.
4. If your trailer has two drop leg jacks, lower them both
to the ground.
5. Unlock the release lever on the fifth wheel:
6. Slowly drive the tow vehicle away from the trailer.
NOTICE
If the drop leg jacks are not set at the same level, one
of the drop leg jacks can be overloaded and can be
damaged.
