Hydraulic system


Depressurize the system!
– Switch off the hydraulic unit before working on the circuit.
– Check the system using pressure gauges to make sure that the entire circuit is fully depressurized.
– Please note that energy may be stored in reservoirs, cylinders with spring load and
cylinders with weight load. Further information on this issue is
available in the data sheets and operating instructions included with the components.

Limit system pressure to 6 MPa or 6.5 MPa (60/65 bar).

Risk of injury due to oil temperatures greater than 50° C!
Hydraulic oil with a temperature greater than 50° C may result in burns or scalding.

Risk of injury when switching on the hydraulic unit!
Cylinders may advance and retract automatically.

Connecting the hoses
– Never connect or disconnect the hoses when the hydraulic unit is running, or while under pressure!
Couplings must be connected when unpressurized.
– Place the coupling socket vertically onto the coupling nipple.
The coupling socket and the coupling nipple must not be fitted askew.
– After each disconnection, make sure that the couplings have closed themselves!

Before commissioning, make sure that all tank lines have been connected and that all couplings have
been fitted securely.
