While hydraulic power is operating,
raise the front end of the semitrailer with the
TRAILER TILT CONTROL (See Figure 3-2)
until weight is off the landing gear. Raise
landing gear. Secure each leg with a park
stand retaining pin in fully retracted position
before transporting.
Lower the front end with the TRAILER
TILT CONTROL lever until the semitrailer is
fully lowered. Hold lever in the down position
until hydraulic system works against the bot-
tomed out hydraulic tilt cylinders.
Verify that the traveling undercarriage is
completely slid back to transport position.
Shut off hydraulic power.
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 that tire inflation matches the
pressure listed on the tire.
Check tractor/semitrailer rig for air leaks.
If air leakage is found, repair the defect before
transporting.
Check that the oil in each hub is at the
proper level and free from contamination. If
hubs contain water, dirt, or other foreign mat-
ter, clean them before transporting.
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 trans-
port until defect, or defects, are repaired.
Check your maintenance schedule and
be sure everything is up-to-date.
