Correct use
automatic coupler, ensure that the
hitching operation is completed and
that drawbar eye is secured.
• Raise support foot, turn it to transport
position and secure it with pin and
cotter pin.
Read subsection (4.3), (4.4).
CONNECTING THE SYSTEMS
• Turn off the engine and remove key
from ignition. Immobilise tractor with
parking brake.
• Connect pneumatic braking system
connections (1) to appropriate tractor
sockets - figure (4.1).
First connect the conduit with
a yellow cover (control conduit),
then connect the pneumatic
conduit with a red cover (supply
conduit).
ATTENTION
In the event of a prolonged idle period of the trailer,
the air pressure in the pneumatic brake system may
be insufficient to release the brake shoes. In such a
case, start the tractor's engine and air compressor
and supplement air in the pneumatic system tank.
• Connect the electrical system lead -
7pin (2) - figure (4.1).
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 and pneumatic con-
duits to the tractor, make sure that the hydraulic and
pneumatic systems of the tractor and the trailer are
not under pressure.
Ensure sufficient visibility during hitching.
• Depending on the trailer equipment,
e.g. hydraulic ramps, winch, connect
the appropriate hydraulic system
conduits (3) - figure (4.1).
Ensure correct connection of
the hydraulic conduits of the
hydraulic winch. Conduit with
return valve should be con-
nected to "free drain" socket by-
passing the tractor's hydraulic
distributor.
ADDITIONAL INFORMATION
• After connecting all conduits make
sure that they will not get entangled
in moving parts of the tractor or trailer
during work. If necessary, secure the
conduits.
• Conduct daily inspection of the trailer.
• If the trailer is fully operational, one
may commence work.
• Immediately before driving remove
wheel chocks and release the parking
brake.
