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 line is connected, the braking system will switch to normal mode of
operation (disconnection or interruption of the lines 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.
Trailer may only be hitched to a tractor, which has the appropriate transport hitch,
connection sockets for braking, hydraulic and electrical systems, and hydraulic oil in both
machines is the same type and may be mixed.
When hitching is completed, secure the electrical leads and hydraulic and braking system
conduits in such a way that they do not become entangled in tractor's moving parts and
are not at the risk of breaking or being severed when making turns.
Unhitching the trailer
In order to unhitch the trailer from the tractor follow these steps.
Immobilise tractor and trailer with parking brake.
