DANGER
When hitching, there must be nobody between the trailer and the tractor. When hitching
the machine, tractor driver must exercise caution and make sure that nobody is present in
the hazard zone.
When connecting the hydraulic conduits to the tractor, make sure that the tractor
hydraulic system and trailer are not under pressure.
Ensure sufficient visibility during hitching.
Exercise particular caution during folding support - danger of severing limbs.
While connecting the braking system conduits (in pneumatic double conduit system and
pneumatic-hydraulic system) the correct sequence of conduit connection is very important.
First connect the yellow connector to yellow socket in the tractor and only then connect the
red connector to the red socket in the tractor. Once the 2nd conduit is connected, the brake
release system will switch to normal mode of operation (disconnection or interruption of the
air conduits causes the trailer's braking system control valve to automatically apply brakes).
Conduits are marked with coloured protective covers, which identify the appropriate system
conduit.
Disconnecting the trailer
In order to disconnect the trailer from the tractor follow these steps.
Immobilise tractor and trailer with parking brake.
