
WARNING
1. With hydraulic power operating, raise landing gear:

CAUTION
a. For pin drop landing gear, activate the TRAILER
TILT lever “UP” until weight is off the landing
gear. Raise landing gear (See Figure 3-4.) (See
“Trailer Tilt Lever” on page 3-8 for operation
of TRAILER TILT lever.)
Secure each leg with a
park stand retaining pin in the full “up” position
before transporting.
b. For crank landing gear, retract landing gear by
turning hand crank on control panel
counterclockwise. 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.
2. The LANDING GEAR lever is located above the
hydraulic control panel. It has three positions:

CAUTION
3. Activate the TRAILER TILT lever (See “Trailer Tilt
Lever” on page 3-8.) “DOWN” until the semitrailer is
fully lowered. Hold semitrailer tilt lever in the down
position until hydraulic system works against the
bottomed out Hydraulic Tilt Cylinders.
4. Determine that the traveling undercarriage is
completely slid back to transport position. Hold
AXLE
CONTROL lever (See “Axle Control Lever” on
page 3-8.) in the transport position until hydraulic
system works against the fully extended hydraulic
telescopic axle cylinder. Shut off hydraulic power.
5. Check the operation of all lights and signals on the
semitrailer for proper response to switch positions
(stop, right turn, left turn, and clearance). Check
operation of remote function if present.
6. Check tire inflation; adjust as needed to the pressure
listed on the semitrailer VIN plate, located on the
front of the semitrailer.
7. Check tractor/semitrailer rig for air leaks. If air
leakage is found, repair the defect before
transporting.
8. 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.
9. Check tractor air pressure. Pressure must not fall
below 90 psi, even after activating 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 repaired.
Failure to properly set and check parking brake,
and chock wheels when parking and during
storage, could allow movement of the
truck/semitrailer rig resulting in serious personal
injury, death, or damage to property in its path.
Always grip crank handle securely with both
hands. Never shift landing gear under load, leave
the gears in neutral or leave the crank unsecured.
RETRACT In this position, the landing gear is
pulled up off the ground.
CENTER This is neutral position.
EXTEND In this position, the landing gear is
lowered to the ground.
1. Landing gear legs must be fully retracted. Pin
drop landing gear and hydraulic operated
landing gear must be secured with pins
before operating or moving semitrailer.
2. If semitrailer is loaded when operating
landing gear, load must be centered on the
trailer.
3. Do not tilt semitrailer with landing gear on
ground.
