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 due caution during folding support - danger of severing limbs.
ATTENTION
Ensure compatibility of oils in tractor hydraulic system and in the trailer hydraulic tipping
system.
When connecting the hydraulic braking system conduits, first connect the hydraulic conduit.
Then, connect the electric lead of the electro-hydraulic brake valve. After connecting the
electric lead and starting the tractor (energizing the connection lead), the braking system is
ready for work. If the connection lead is not energized, the trailer will be immobilized with
brake.
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.
Unhitching the trailer
In order to unhitch the trailer from the tractor follow these steps.
