OPERATING INSTRUCTIONS
3-3
Connecting Tractor Services to
the Semitrailer
1. Connect the tractor 7-way electrical plug to the
electrical receptacle on the front of the semitrailer
(See Figure 3-1.)
IMPORTANT
The key on the plug and the keyway in the socket
must be properly aligned before inserting the plug
into the semitrailer socket.
2. If you have not already done so, connect the tractor
hydraulic lines to the semitrailer, unless your
semitrailer is equipped with the auxiliary hydraulic
power engine package.
IMPORTANT
Some oil may need to be removed from the tractor
reservoir to allow room for 12 gallons of additional
oil displaced from the semitrailer hydraulic system.
Tractor and Semitrailer
Check-Out
1. While hydraulic power is operating, raise the front
end of the semitrailer with the
TRAILER TILT lever
until weight is off the landing gear (See Figure 3-2.)
Raise landing gear. If pin drop leg, secure each leg
with a retaining pin in fully retracted position before
transporting.

WARNING
2. Lower the front end with the TRAILER TILT lever
until the semitrailer is fully lowered. Hold lever in the
down position until hydraulic system works against
the bottomed out hydraulic tilt cylinders.
3. Verify that the traveling undercarriage is completely
slid back to transport position. Shut off hydraulic
power.
4. Check the operation of all lights and signals on the
semitrailer for proper response to switch positions
(stop, right turn, left turn and clearance).
5. Check that tire inflation matches the pressure listed
on the tire.
6. Check tractor/semitrailer combination for air leaks. If
air leakage is found, repair the defect before
transporting.
7. Check that the oil in each hub is at the proper level
and free from contamination. If hubs contain water,
dirt, or other foreign matter, clean them before
transporting.
8. Check tractor air pressure. Pressure must not fall
below 65 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.
