Connect pneumatic conduit marked black with black socket in tractor.
Connect hydraulic braking system conduits (applies to trailer version with
hydraulic braking system).
Hydraulic braking system conduit is marked with information decal (9)
– table (2.1).
Connect hydraulic tipping system conduits.
Hydraulic tipping system conduit is marked with information decal (10)

Connect main lead supplying electrical lighting system.
Raise the support to driving position.
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 hydraulic
system of the tractor and the hydraulic system of the trailer are not under pressure.
Ensure sufficient visibility during hitching.
Exercise particular caution during folding support - danger of severing limbs.
During connection of braking system conduits (pneumatic double conduit) 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.
ATTENTION
Ensure compatibility of oils in tractor hydraulic system and in the trailer hydraulic tipping
system.
