Environmental protection

The packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.
Electrical and electronic appliances contain valu-able, recyclable materials and often components such as batteries, rechargeable batteries or oil, which – if handled or disposed of incorrectly – can pose a potential threat to human health and the environment. However, these components are required for the correct operation of the appliance. Appliances marked by this symbol are not allowed to be disposed of together with the household rubbish.
Notes on the content materials (REACH)
Current information on content materials can be found at: www.kaercher.com/REACH

Accessories and spare parts

Only use original accessories and original spare parts. They ensure that the appliance will run fault-free and safely. Information on accessories and spare parts can be found at www.kaercher.com.

Scope of delivery

Check the contents for completeness when unpacking. If any accessories are missing or in the event of any shipping damage, please notify your dealer.

Safety instructions

• It is essential that you read the safety instructions 5.951-949.0 before initial start-up.
• Observe the national regulations for liquid jet cleaners.
• Observe the national accident prevention regulations. Liquid jet cleaners must be tested regularly. The test result must be recorded in writing.
• Do not modify the device or accessories.

Safety devices

CAUTION
Missing or modified safety devices
Safety devices are provided for your own protection. Never modify or bypass safety devices.

Safety lever
The safety lever on the high-pressure gun prevents the device from being switched on inadvertently.
Overflow valve
If the high-pressure gun is closed, the overflow valve opens and the entire water volume will flow back to the pump suction side.
The overflow valve is set by the manufacturer and sealed. Setting shall only be carried out by Customer Service.

Symbols on the device

Do not aim the high-pressure jet at persons, animals, live electrical equipment or the device itself.
Protect the device against frost.
According to applicable regulations, the device must never be used with the drinking water network without a system separator. Ensure that the connection to your house water system, with which the high-pressure cleaner is operated, is equipped with a system separator according to EN 12729 type BA. Water that has flowed through a system separator is classified as undrinkable. Always connect the system separator to the water inlet and never directly to the device.

WARNING
The high nozzle outlet speed of the high-pressure water jet results in a high noise level that can cause discomfort or hearing damage (e.g. tinnitus) to persons in the immediate vicinity. A continuously high noise level can result in deafness.

• Wear the prescribed personal protective equipment.
• High noise levels can impair vocal communication and impair or prevent your ability to perceive acoustic warning signs. Never work alone. A second person must be present outside the work area.
