designed to facilitate detecting air leaks. Damaged components should be replaced or
repaired. If leaks appear at connections then tighten the connections. If air continues to
escape, replace connection components or seals with new ones.
Check system tightness:
Visual inspection of the system
During tightness inspection attention should additionally be given to technical condition and
degree of cleanness of the system components. Contact of pneumatic conduit seals etc. with
oil, grease, petrol etc. may cause damage and accelerate the ageing process. Bent,
permanently deformed, cut or worn conduits should be replaced.

ATTENTION
Repair, exchange or regeneration of pneumatic system components may only be
performed in a specialised workshop.

CLEANING THE AIR FILTERS

Depending on trailer working conditions, but not less than once in three months, take out and
clean air filter elements, which are located in pneumatic system connection conduits. Filter
elements are used many times and are not subject to change unless they are mechanically
damaged.
• after travelling the first 1 000 km,
• each time after making repairs or changing system components,
• annually.
• Conduct inspection of system at the same time as when checking tightness.
