the 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

in their designated socket. Before the winter, it is recommended to preserve the seal with
special preparations (e.g. silicon grease for rubber elements).
Each time before hitching the machine, inspect technical condition and cleanness of
connectors and sockets in tractor. If necessary, clean or repair tractor sockets.
