DANGER
Before disconnecting wires and drawbar eye, close
tractor cab and secure it against unauthorized ac-
cess. The tractor engine must be turned off.
DANGER
The use of defective trailers is forbidden.
CAUTION
If the trailer is parked for a long time, it may turn out
that the air pressure in the pneumatic braking sys-
tem is insufficient to release the brake shoes. In this
case, after starting the tractor and the air compres-
sor, wait until the air in the pneumatic tank is topped
up.
CAUTION
When disconnecting the pneumatic conduits of a
2-wire system, first disconnect the conduit marked
red and then the conduit marked yellow.
ADVICE
Before disconnecting the hydraulic hoses, reduce
the pressure in the hoses. For this purpose move
the lever of the distributor of the external hydraulic
system of the tractor to the floating position with the
tractor engine running.
CAUTION
After completing the coupling, secure the hydraulic,
braking and electrical wiring in such a way that they
do not become entangled in the moving parts of the
agricultural tractor during travel and are not exposed
to kinking or cutting during turning.
