7.2.3 Pressure relief valve

The pressure relief valves are adjusted to a set pressure and secured.

NOTE:

The system pressure that is generated between the Mobile Selection Manifold

and hydraulic cylinders is not identical to the system pressure between the

Mobile Selection Manifold and hydraulic unit! (Consult the "Technical Data" data

WARNING / CAUTION / ATTENTION!

The pressures set on the pressure relief valves may not be changed without the

direct permission of LUKAS!

7.3 Removal of the components

The components are removed in reverse order from the installation.

ATTENTION!

Before the nal removal of the system components, it is absolutely essential to

ensure:

- that the load is located in a stable, immovable position.

- all hydraulic cylinders are retracted to approx. 10 mm (0.39 in.).

- the hydraulic unit is stopped.

- the hose lines to the hydraulic cylinders are depressurised.

7.2.2 Distribution valve (cover sheet, item 2)

The movement is controlled with the distribution valve. Turning the hand wheel controls

which port is supplied with more hydraulic uid. The uid supply of the other port can be

throttled down to almost 0.

The extension and retraction speed of the hydraulic cylinders is indirectly affected by

controlling the uid quantity.
