Pneumatic and hydraulic systems
The pneumatic system is under high pressure. When connecting the pneumatic lines
to the tractor's pneumatic system, make sure that the valves on the side of the tractor and the
Trailer are not pressurised. Check the pneumatic connection on a regular basis, and replace
damaged components and ageing parts. Check the tightness of the hoses. Air leakage is not
permitted. The replacement of lines must comply with the manufacturer's technical
requirements. Replace flexible lines every five years, unless damage has been found earlier.
Before starting repair work, de-pressurise the air system and switch off the tractor’s
engine. Only an authorised representative of the Trailer’s manufacturer can make repairs of
the pneumatic system.
The Trailer’s hydraulic system is also under high pressure. Check the condition of the
hydraulic lines on a regular basis. Oil leaks are not permitted. There is a shut-off valve in the
hydraulic system, which limits the tilting angle of the Trailer's body. The user is not permitted
to adjust the length of the control rope.
When connecting the hydraulic hoses to the tractor, make sure that the tractor's and
Trailer's hydraulic systems are not under pressure. If necessary, reduce the residual pressure
of the system.
