Low-pressure hose connection
The machine is supplied with water via the low-pressure hose.
The water flows through the water filter so that the water supplied
to the high-pressure water pump is clean.
The high-pressure water pump pumps the water into the high-pres-
sure hose at the preset water pressure.
The pressure limiting valve is sealed. It limits the maximum water
pressure. Excess water pressure is dumped via the drain hose.
Adjust the current water pressure by turning the unloader and view
the reading on the pressure gauge.
The unloader limits the water pressure, excess water is depressuri-
zed and runs through the bypass hose back into the water inlet.
