The operating pressure required for cutting the cable is
generated in the pump.
The pump is operated by means of a foot pedal.

The
oil discharge pedal
enables the return of the insulating oil to the pump tank and is used to open
the blades of the cutting head on termination of the cutting operation.
The
manometer
shows the operating pressure present in the system.
The pressure field with red background represents the maximum acceptable overpressure operat-
ing limit which cannot be exceeded.
On reaching the maximum allowed operating pressure, the maximum pressure valve inside the
pump stops any further increase in pressure.
The
earth connection terminal
on the base of the pump enables the connection of an earthing
cable. To avoid the danger of tension gradients, the pump must be connected to the environment
potential (grate, steel sheet, etc.).
