For your safety
Before you use the cleaner for the first time, read these operating instructions and take special note of the accompanying booklet “Safety Instructions for High-Pressure Cleaners” No. 5.951-949.
Symbols on the machine
High-pressure jets can be dangerous if improperly used. The jet must not be directed at per- sons, animals, live electrical equipment, or at the appliance itself.
The appliance is not suited for use in the drinking water supply network. It is necessary to install a suitable system separator from Kaercher if the device is to be used in the drinking water supply network.
Use of the cleaner
Use this unit exclusively for

• cleaning with a high-pressure jet and deter- gent (e.g. cleaning of machines, vehicles, buildings, tools),
• cleaning with a high-pressure jet without detergent (e.g. cleaning facades, terraces, gardening equipment).

For stubborn dirt, we recommend the dirt blaster as an optional accessory (for HD … Plus included in the delivery).

Safety features

Overflow valve with pressure switch
On reducing the flow rate with the pressure and flow control, the relief valve opens and part of the water runs back to the suction side of the pump.
If the lever of the hand-held spray gun is released, the pressure switch switches the pump off. If the lever is retracted, the pressure switch switches the pump on again.
Safety valve
The safety valve opens when the admissible operating excess pressure is exceeded; the water flows back to the pump suction side. The overflow valve, pressure switch, and safety valve are present in the factory and are sealed.
Adjustments are made only by Customer Service.
Protection of the environment, disposal
The packaging material can be recycled. Please do not place the packaging into the ordinary refuse for disposal, but arrange for the proper recycling.
