With hydraulic power operating, raise
landing gear:
CAUTION
ALWAYS GRIP CRANK HANDLE SE-
CURELY WITH BOTH HANDS. NEVER
SHIFT LANDING GEAR UNDER LOAD,
LEAVE THE GEARS IN NEUTRAL OR
LEAVE THE CRANK UNSECURED.
a.
For crank landing gear, retract landing gear
by turning hand crank on control panel coun-
terclockwise. Use low gear until the load is off
the landing gear. Then shift to high gear and
continue cranking until fully retracted. Leave
the landing gear in high gear.
b.
For pin drop landing gear, unit weight is off
the landing gear. Raise landing gear. Secure
each leg with a park stand retaining pin in the
full “up” position before transporting.
CAUTION
1. LANDING GEAR LEGS MUST BE
FULLY RETRACTED AND SECURED
WITH PINS BEFORE OPERATING OR
MOVING SEMITRAILER.
2. IF SEMITRAILER IS LOADED WHEN
OPERATING LANDING GEAR, LOAD

3-5.2
Determine that the traveling undercar-
riage is completely slid back to transport po-
sition. Hold
TAIL/AXLE CONTROL LEVER
(See Section 3-9)
in the transport position
until hydraulic system works against the fully
extended hydraulic axle cylinder.
3-5.3
Check the operation of all lights and sig-
nals on the semitrailer for proper response to
switch positions (stop, right turn, left turn,
and clearance). Check operation of remote
function if present. Shut off hydraulic power.
3-5.4
Check tire inflation, adjust as needed to
the pressure listed on the semitrailer VIN
plate, located on the front of the semitrailer.
3-5.5
Check
tractor/semitrailer
rig
for
air
leaks. If air leakage is found, repair the de-
fect before transporting.
3-5.6
Check the oil in each hub for proper
level and freedom from contamination. If
hubs are contaminated with water, dirt or
some other foreign material, clean before
transporting.
3-5.7
Check tractor air pressure. Pressure
must not fall below 90 psi, even after activat-
ing brakes a couple of times. Set parking
brake and carefully remove all wheel chocks.
Set emergency brake and try pulling forward.
The semitrailer wheels must not rotate. If
semitrailer brakes do not apply,
DO NOT
transport until defect, or defects, are re-
paired.
