Please follow the national rules and regulations for accident prevention of the respective country. Fluid spray jets must be tested regularly and the results of these tests must be documented in writing.

Hazard levels

DANGER
Pointer to immediate danger, which leads to severe injuries or death.

WARNING
Pointer to a possibly dangerous situation, which can lead to severe injuries or death.
CAUTION
Pointer to a possibly dangerous situation, which can lead to minor injuries.
ATTENTION
Pointer to a possibly dangerous situation, which can lead to property damage.

Symbols on the machine

High-pressure jets can be dangerous if improperly used. The jet may not be directed at persons, animals, live electrical equipment or at the appliance itself.
According to applicable regulations, the appliance must never be used on the drinking water net without a system separator. A suitable system separator by KÄRCHER or alternatively a system separator according to EN 12729 type BA must be used.
Water that was flowing through a system separator is considered non-drinkable.

CAUTION
Always connect the system separator to the water supply, never directly to the appliance!

Proper use

Use this high-pressure cleaner exclusively for

Cleaning using low-pressure jet and detergent (for e.g. for cleaning machines, cars, buildings, tools),
For cleaning using high pressure jet without detergent (for e.g. for cleaning facades, terraces, garden appliances).
For stubborn dirt, we recommend the use of the dirt blaster as a special accessory. Quality requirements for water:

ATTENTION

Only clean water may be used as a high-pressure medium. Impurities will lead to increased wear and tear or formation of deposits in the appliance.
If recycled water is used, the following limit values must not be exceeded.

pH value	6,5…9,5
electrical conductivity *	Conductivity fresh water

Safety Devices
Safety devices serve for the protection of the user and must not be put out of operation or bypassed with respect to their function.

Overflow valve with pressure switch

While reducing the water supply/quantity regulation at the pump head, the overflow valve opens and part of the water flows back to the pump suck side.
If the pulling lever on the trigger gun is released the pressure switch turns off the pump, the high-pressure jet is stopped. If the pulling lever is pulled the pump is turned on again.
The overflow valve and pressure switch are set and sealed at the factory. Setting only by customer service.

Motor protection switch
The motor protection switch switches off the device if the power consumption is high.

Environmental protection

The packaging material can be recycled. Please do not place the packaging into the ordinary refuse for disposal, but arrange for the proper recycling.
Old appliances contain valuable materials that can be recycled; these should be sent for recycling. Batteries, oil, and similar substances must not enter the environment. Please dispose of your old appliances using appropriate collection systems.
Electrical and electronic devices often con-tain components which could potentially pose a danger to human health and the environment if handled or disposed of incor-rectly. However, these components are necessary for the proper operation of the device. Devices marked with this symbol must not be disposed of with regular household rubbish.
Notes about the ingredients (REACH) You will find current information about the ingredients at: www.kaercher.com/REACH

Open the water supply.
Screw the suction hose with filter (order no. 4.440-238.0) to the water connection.

Deaerate the appliance:

Unscrew the nozzle. Switch on the appliance and let it run until the water exiting is bubble-free.
At the end let the appliance run for approx. 10 seconds – then switch off. Repeat the procedure for a couple of times.
Switch off the appliance and fit the nozzle again.

Operation

DANGER
Risk of explosion!
Do not spray flammable liquids.
If the appliance is used in hazardous areas (e.g. filling stations) the corresponding safety regulations must be observed. Risk of injury!
