Trailer conduits connectors and sockets on the tractor must be free of dirt. Pneumatic system
connectors are equipped with rubber seals that cannot be damaged or contaminated.
DANGER
During aggregation, no unauthorized persons are allowed between the trailer and the
tractor. When coupling the machine, the tractor driver should maintain extreme caution
during operation and make sure that no unauthorized persons are present in the danger
zone.
Before connecting the trailer, check the technical condition of the trailer and tractor
coupling system as well as connecting elements for electrical, hydraulic and pneumatic
systems.
Maintain extreme caution when connecting the machine.
When connecting the hydraulic hoses to the tractor, make sure that the tractor and trailer
hydraulic systems are not under pressure.
When connecting the braking system lines, the correct order of connection is very important.
First, connect the yellow connector to the yellow socket on the tractor, and then connect the
red connector to the red socket on the tractor. After connecting the second conduit, the brake
release system will switch to normal operation mode (disconnection or interruption of the air
conduits causes the trailer control valve to automatically move to the position for actuating
the pneumatic brakes of the machine).
In order to connect the trailer with the tractor, perform the following actions in order. The
trailer should be immobilized with the parking brake.
