ATTENTION
Trailer may only be hitched to a technically reliable tractor, which has the
appropriate hitch, required connection sockets for braking, hydraulic and
electrical systems, and hydraulic oil in both machines is of 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.
Ensure compatibility of oils in tractor hydraulic system and in the trailer
hydraulic system.
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 second conduit is connected, the brake applying system will switch to
normal mode of operation (when pressure in the trailer's air tank reaches the proper level, the
trailer's control valve will automatically switch to the position in which the machine brakes are
applied).
TIP
Hydraulic and pneumatic conduits are marked with coloured protective covers,
which identify the appropriate system conduit.
Unhitching the trailer
In order to unhitch the trailer from the tractor follow these steps.
Immobilise tractor and trailer with parking brake.
DANGER
Do NOT unhitch the trailer when the load box is raised.
Exercise caution when unhitching the trailer from the tractor. Ensure good
visibility. Unless it is necessary, do not go between tractor and trailer.
Before disconnecting conduits and drawbar eye, close tractor cab and secure it
against access by unauthorised persons. Turn off tractor engine.
Place chocks under trailer wheel.
Wheel chocks shall be so placed that one is in front of the wheel and
the second is behind wheel of rear axle - see section 2.
