Pronar T683

SECTION 3

3.18

The system is equipped with a hydraulic lock (5) located on the cylinder (4). Application of

hydraulic lock improves safety of trailer operation. During raising or lowering, the support may

damage conduits (rupture, loss of tightness). In such a case, the hydraulic lock will lock

cylinder (4) in a fixed position.

TIP

The hydraulic system of the support is filled with L-HL32 Lotos hydraulic oil.
