Read these original instructions and the enclosed safety instructions before using the device for the first time. Act in accordance with them.

Keep both books for future reference or for future owners.

• If the operating instructions and safety instructions are not observed, the device can be damaged and dangers could arise for users and other persons.

• Notify the dealer immediately in the case of shipping damage.

• Check the package contents when unpacking for missing accessories or for damage. Scope of delivery see illustration A.

• At operating elevations of approx. 800 m above sea level or higher, please contact your dealer to have the burner setting adjusted to the elevation and reduced oxygen content.

The following safety instructions apply to the device:

• Observe the respectively applicable national regulations for liquid jet cleaners.

• Observe the respectively applicable national accident prevention regulations. Liquid jet cleaners must be tested regularly and the results of the test recorded in writing.

• Note that the heating system in the device is classified as a furnace. Furnaces must be inspected regularly according to the applicable national regulations.

• No modifications may be made to the device or accessories.

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

• When reducing the water volume at the pump head or with the pressure/quantity regulator on the high-pressure gun, the overflow valve opens and part of the water flows back to the pump suction side.

• If the high-pressure gun is closed so that all the water flows back to the pump suction side, the pressure switch on the overflow valve switches off the pump.

• If the high-pressure gun is opened again, the pressure switch on the cylinder head switches the pump on again.

• The overflow valve is set and sealed at the factory. The adjustment is performed only by customer service.

• The safety valve opens if the overflow valve or pressure switch is faulty.

• The safety valve is adjusted and sealed at the factory. The adjustment is performed only by customer service.

The water shortage safeguard prevents the burner from activating in case of water scarcity. If there is a lack of water during operation, the burner and the fuel supply are switched off.

The exhaust gas thermostat switches the device off when the emission temperature is too high.
