All structural hardware (wheel
chocks, side underrun guards, lad-
der and etc.) are in their place and

5.2. Semi-Trailer and Tractor Cou-
pling
Apply the following steps to couple the
semi-trailer with the tractor:
•
Check that kingpin and its coup-
lings are normal. Make sure that
there is an adequate amount of
grease oil on the fifth wheel, top-
connection plate and kingpin that
will ensure undamaged coupling
and not contain any dust and con-
taminant.
•
Lower the height of the rear sus-
pension airbags of the tractor until
it can be inserted in the king pin
section of the semi-trailer.
•
Set the 5th wheel locking system
on the tractor to the "On" position.
•
Adjust the height of the semi-trailer
to insert it into the tractor. The he-
ight of the semi-trailer can be ad-
justed with the mechanical landing
gear. Prevent the movement of the
semi-trailer by using the parking
brake. Put wheel chock at the rear
of the wheels for safety.
•
Move the tractor, fifth wheel until it
touches the top-connection plate
of the semi-trailer and moves
backwards slowly on the same le-
vel. The fifth wheel will slide smo-
othly under the top-connection
plate and enter the kingpin's shoes
and lock automatically with the in-
tensity of impact.
•
Raise the landing legs of the semi-
trailer and insert the landing legs
arm to its place.
•
Connect the air, electrical and EBS
cable and hoses to their places on
the tractor. Be sure that all the
functions are working properly.
•
If the vehicle has a parking brake,
release the parking brake.
If your vehicle is driven at the
wrong 5th wheel height, mal-
functions may occur in the vehi-
cle. You may have height problems. The
vehicle must be driven at the correct
fifth wheel height.
Apply the following steps to uncouple the
semi-trailer with the tractor:
