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 while folding the 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 braking system will switch to normal mode of
operation (disconnection or interruption of the 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.
ATTENTION
Trailer may only be hitched to a tractor, which has the appropriate 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.
