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.
Be especially careful when hitching the machine to tractor.
When connecting the hydraulic conduits to the tractor, make sure that the tractor
hydraulic system and trailer are not under pressure.
IMPORTANT!
Trailer may only be hitched to a tractor, which has the appropriate connection sockets for
braking, hydraulic and electrical, and hydraulic oil in both machines is the same type and
also the tractor hitch is capable of bearing the vertical drawbar loading of the loaded
trailer.
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 severed when making turns.
During connection of braking system conduits the correct sequence of conduit connection is
very important. First in sequence connect yellow coloured plug to yellow socket in tractor,
and then afterwards the red coloured plug to the red socket in 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).
