Read the operating instructions before starting the device.

Safety devices protect the user and may not be disabled or functionally circumvented.

The safety latch on the high-pressure gun prevents the high pressure water jet from being triggered unintentionally.

The pressure relief valve opens when the high-pressure gun is closed. This causes water to be returned from the high-pressure outlet to the suction side of the high-pressure pump. This prevents the maximum permissible working pressure from being exceeded.

The pressure relief valve is set and sealed at the factory. Only the Customer Service department is authorised to adjust the pressure relief valve.

The safety valve opens when the maximum permissible operating pressure is exceeded and the water flows into the open.

The safety valve is set and sealed at the factory. Only the Customer Service department is authorised to adjust the safety valve.

Only the Advanced version has this function.

The thermostat valve protects the high-pressure pump from overheating in circulation mode when the high-pressure gun is closes. The thermostat valve opens when the water temperature exceeds 80 °C and channels the hot water into the open.
