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 final 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 fluid. The fluid 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 fluid quantity.
