SECTION 4 Pronar T286
4.8
In case of straight hydraulic support or folding hydraulic support, start
a proper section of the manifold in the tractor in order to raise the
support maximally.
In case of folding hydraulic support, fold and secure the cylinder
according to chapter 4.3.2.
Set valve (4) in hydraulic support to "Z" position - figure (4.2) and set the
manifold lever in the tractor to "neutral" position.
Turn off tractor engine. Ensure that unauthorised persons do not have access
to the tractor cab.
Connect the drawbar's hydraulic system (to the sockets of a single section of
the tractor's external hydraulic system).
Connect pneumatic system conduits.
Keep the correct sequence of conduit connections. 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 2nd line 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).
If the brakes do not react after connecting the conduits, pressure in
the tank may be too low. Increase the pressure to proper level in order
to ensure operation of the system.
Connect hydraulic braking system conduit (applies to trailer version with
hydraulic braking system).
The connection socket is different than in other systems (female
socket).
Connect the conduits of the hydraulic system of the turning interlock (to the
sockets of a single section of the tractor's external hydraulic system).
Connect the central hydraulic system conduits.
