5.4.3 CLEANING AND MAINTAINING PNEUMATIC CONDUIT
CONNECTIONS AND PNEUMATIC SOCKETS
DANGER
Unreliable and dirty trailer connections may cause unreliability and faulty
functioning of brake system.
Connection with damaged body should be replaced. In event of damage to cover or seal,
change these elements for new reliable elements. Contact of pneumatic connection 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 cover or placed
in their designated socket. 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.
