wheel jaws are locked per the fifth wheel manufacturer's
recommendations. Reapply the tractor parking brake.

Failure to retract the landing gear fully
before moving the trailer could result

7.4 Landing Gear Operation During Uncoupling
NOTE: For specific uncoupling instructions relating to
the fifth wheel, tractor, and trailer, refer to the
respective manufacturer's instructions.
1. Position the tractor and the trailer on a well lit, level
surface, clear of persons and obstacles. Verify that the
surface beneath the landing gear is capable of supporting
the trailer weight. Also ensure that the tractor and trailer
are in line with each other.
NOTE: If necessary, place landing gear pads on a support
plank to prevent the landing gear from sinking
into the supportive surface. (This is especially
important with liquid cargo, where a shift in the
contents could overturn the trailer).
Failure to align the tractor and trailer
properly could result in damage to the
landing gear.
Failure to rest the landing gear pads on
a hard, flat surface, could result in trailer
tip-over which, if not avoided, could
result in death or serious injury.
2. Engage the trailer brakes. Slowly back tractor tightly against
the trailer. Set the tractor brakes, and chock the trailer wheels.
3. Engage the landing gear crank handle and shift to high
gear (Figure 23).
