ATTENTION!
Use only high-quality lubricants! The hubs must be with covers!
The durability of tractor semi-trailers depends on the conditions and intensity of use, timely
maintenance and servicing. Any negligence may have adverse consequences. Timely removed failures require
minimal cost but produce maximum effect.
The failures of the semi-trailer can be identified and quickly removed only if constant cleaning and
monitoring of the technical condition is ensured. If the semi-trailer is clean, it is easier to detect shortcomings.
Attention shall be paid to the lubrication of assemblies.
It is preferable to store it under a roof thus avoiding atmospheric effects.
Daily maintenance:
checking of thread connections and their protection against undesirable loosening;
checking of the condition of pivot connections (for wear and for the reliably of the pinning of
the axles).
checking of the tightness of the hydraulic system and elimination of inconsistencies;
checking of the tightness of the pneumatic system and elimination of damage;
checking of the operation of mechanisms;
compliance of lubrication with the requirements of the manual;
checking of the tyre pressure in accordance with the requirements of the manual;
checking of the closing of the tailgate and discharge port;
checking of the operation of the brake and light signalling systems.
When performing minor repairs, pay attention to the cleanliness of works and correct installation and
adjustment of parts.
Dismantled parts shall be stored and protected against contamination. Pay attention to the preservation
of bearings.
