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 packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.

Electrical and electronic devices contain valuable, recyclable materials and often components such as batteries, rechargeable batteries or oil, which - if handled or disposed of incorrectly - can pose a potential danger to human health and the environment. However, these components are required for the correct operation of the device. Devices marked by this symbol are not allowed to be disposed of together with the household rubbish.

Current information on content materials can be found at: www.kaercher.de/REACH

Please do not allow engine oil, heating oil, diesel and petrol to enter the environment. Please protect the ground and dispose of old oil in an environmentally friendly manner.

Only use the device for cleaning, e.g. machines, vehicles, buildings, tools, façades, terraces and garden equipment.

The following limit values apply to the water supply:

• pH value: 6.5-9.5

• Electrical conductivity: Conductivity of fresh water + 1200 µS/cm, maximum conductivity 2000 µS/cm

• Settleable particles (sample volume 1 l, settling time 30 minutes): < 0.5 mg/l

• Filterable particles: < 50 mg/l, no abrasive substances

• Hydrocarbons: < 20 mg/l

• Chloride: < 300 mg/l

• Sulphate: < 240 mg/l

• Calcium: < 200 mg/l

• Total hardness: < 28 °dH, < 50° TH, < 500 ppm (mg CaCO₃/l)

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.

• To avoid hazards from excessive temperatures, you must set the pressure/quantity regulator of the pump unit to MAX at work temperatures above 60 °C.

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.

• When the high-pressure gun is closed, the pressure relief valve opens and all the water flows back to the pump suction side. The pressure switch on the overflow valve sends a signal to the control unit, which switches the pump off after approx. 30 seconds of after-running time.

• If the high-pressure gun is opened again, the pressure switch at the overflow valve 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 system pressure is too high.

• 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 switching on when there is a lack of water.

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

The flame monitoring system monitors the brightness of the flame on the burner and switches the burner off in the event of a fault.

The device current is limited by the HDS control circuit board. In addition, the fan motor and the pump motor are each protected by a winding protection contact.

The temperature sensor switches the burner off when the set water temperature is reached.

The safety catch on the high-pressure gun prevents the device from being switched on inadvertently.

If the device is not used for 30 minutes, the device switches off. The readiness time can be activated and deactivated by customer service via the service menu.
