5.3.6 CLEANING AND MAINTAINING PNEUMATIC LINE CONNECTIONS AND
PNEUMATIC SOCKETS
DANGER
Unreliable and dirty trailer connections may cause unreliability and faulty functioning of
braking system.
Damaged connection body or connection socket to second trailer should be replaced. In
event of damage to cover or seal, change these elements for new reliable elements. Contact
of pneumatic connector seals with oils, grease, petrol etc. may cause damage and accelerate
ageing process.
If the trailer is unhitched from the tractor, connections should be protected by covers or
placed in their designated sockets. Before the winter period it is recommended to preserve
the seal with special preparations (e.g. silicon grease for rubber elements).
Each time before connection of the machine inspect technical condition and cleanness of
contacts and sockets in tractor. If necessary clean or repair tractor socket.
