Hydraulic block safety devices

The hydraulic block features three solenoid valves with possible manual by-pass.
These solenoid valves, indicated with 1-2-3, are part of the safety system of the
machine and

must never be operated manually

ATTENTION: If the valve 3 is not fully inserted by pressing and turning

clockwise (hearing a click) and the valves 1-2 are all unscrewed and locked

with a seal, the safety of the machine will be compromised.
