| Maximum working pressure | 12 MPa (120 bar) |
| Water flow rate | 500 L/h (8.3 L/min) |

When the machine is stationary, read the oil‑pressure value on the display; the oil level must be above two marks.
The safety valve opens when the pressure/flow control reduces flow, allowing water to return to the pump suction side.
The filter in the water connector should be cleaned regularly, as described in the maintenance section.
Rinse the hose and filter with clean water, run the machine with clean water for one minute, then store it in a frost‑free location.
