5.3.6 CLEANING AND MAINTENANCE OF PNEUMATIC SOCKETS AND LINE
CONNECTORS
DANGER
Unreliable and dirty trailer connectors may cause faulty functioning of braking system.
Damaged connector body or sockets for connecting the second trailer should be replaced. In
case of damage to cover or seal, change these elements with new reliable ones. Contact of
pneumatic connector seals with oils, grease, petrol etc. may cause damage and accelerate
ageing process.
If the the trailer is disconnected from a tractor, connectors should be protected by cover or
placed in sockets specially designated for this purpose. Before the winter season it is
recommended to preserve the seal with special compounds (e.g. silicon grease for rubber
elements).
Each time before hitching the the machine, inspect technical condition and cleanness of
connectors and sockets in a tractor. If necessary, clean or repair tractor socket.
5.3.7 INSTALLATION OF SINGLE-LINE PNEUMATIC SYSTEM
The standard version of the trailer is fitted with a twin-line pneumatic braking system. If use of
single-line pneumatic system is required, machine's user can rebuild the system – figure
(5.9). Elements required to alter the system are delivered as the standard equipment of the
trailer.
Sequence of rebuild procedure:
Completely reduce the pressure in the air reservoir (3).
Reduction of pressure in tank is achieved by tilting the drain valve
stem (4).
