Rules of use
conduit, the brake release
system will switch to normal op-
eration mode (disconnection or
interruption of the air conduits
causes the trailer control valve
to automatically move to the ma-
chine braking position).
• If the brakes do not react after con-
necting the pneumatic hoses, this
may indicate a low pressure in the
tank. For the system to work, it must
be filled with the correct pressure.
• Connect the hydraulic brake system
hose terminated in the socket (4) -
figure (4.3).
When connecting the trailer with the
overrun brake, it is only necessary to
adjust the height of the drawbar eye in re-
lation to the transport hitch, connect the
hydraulic tipping system and the electrical
installation cable.
CONNECTING OF THE HYDRAULIC

TRICAL INSTALLATION
