SECTION 4 Pronar T669
4.7
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 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). Conduits are marked with coloured protective
covers, which identify the appropriate system conduit.
IMPORTANT!
Trailer may only be hitched to a tractor, which has the appropriate hitch, connection
sockets for braking, hydraulic and electrical systems, and hydraulic oil in both machines
is 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 severed when making turns.
Ensure compatibility of oils in tractor hydraulic system and in the trailer hydraulic system.
Disconnecting the trailer
In order to disconnect the trailer from the tractor carry out the following actions in the
following sequence:
Immobilise tractor and trailer with parking brake.
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.
Lower shear type drawbar support to the ground.
Operate the manifold on the tractor in the direction corresponding to
the support cylinder piston extension.
When the support is lowered, set manifold lever in tractor to "neutral"
position.
Turn off tractor ignition. Ensure that unauthorised persons do not have access
to the tractor cab.
