Safety instructions

Please read and comply with these original instructions prior to the initial operation of your appliance and store them for later use or subsequent owners.

Apart from the notes contained herein the general safety provisions and rules for the prevention of accidents of the legislator must be observed.

Warnings and notes that are attached on the appliance provide important notes for the safe operation.

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.

Safe handling

DANGER

The user must use the appliance as intended. The person must consider the local conditions and must pay attention to other persons in the vicinity when working with the appliance.
Check important components, such as high-pressure hose, hand spray gun and safety installations, for damage prior to every operation. Immediately replace damaged components. Do not operate appliance with damaged components.
High-pressure jets can be dangerous if improperly used. The jet may not be directed at persons, animals, live electri cal equipment or at the appliance itself.
The high-pressure jet must not be directed at other persons or the user him-/herself to clean clothing or footwear.
Vehicle tyres/tyre valves are susceptible to damage from the high-pressure jet and may burst. The first indication for this is a discolouration of the tyre. Damaged vehicle tyres/ tyre valves are perilous. Keep a minimum jet distance of 30 cm during cleaning!

WARNING

Do not use the appliance when there are other persons around unless they are also wearing protective clothing.
The appliance must not be perated by children or persons who have not been instructed accordingly.
This appliance is not intended for use by persons with limited physical, sensory or mental capacities or lacking experience and/or skills, unless such persons are accompanied and supervised by a person in charge of their safety or they have received precise instructions on the use of this appliance and have understood the resulting risks.
Children must not play with this appliance.
Supervise children to prevent them from playing with the appliance.

CAUTION

Create stability for the appliance prior to any work on or with the appliance to prevent accidents or damage.
The water jet that is emitted from the high-pressure nozzle results in a repulsion power acting on the hand spray gun. Make sure that you have a firm footing and are also holding the hand spray gun and spray lance firmly.
Never leave the appliance unattended as long as it is in operation.

ATTENTION

In case of extended breaks, switch off the appliance at the appliance switch.
Do not operate the appliance at temperatures below 0 °C.

Other risks

DANGER

The appliance may not be operated in explosive atmospheres.
Never use the appliance to clean objects containing hazardous substances (e.g. asbestos).
Do not spray flammable liquids.
Never draw in fluids containing solvents or undiluted acids and solvents! This includes petrol, paint thinner and heating oil. The spray mist is highly inflammable, explosive and poisonous. Do not use acetone, undiluted acids and solvents, as they corrode the materials used on the appliance.
Keep packaging films away from children, there is a risk of suffocation!

WARNING

According to applicable regulations, the appliance must never be used on the drinking water net without a system separator. Ensure that the connection of your building water installation on which the high-pressure cleaner is operated is equipped with a system separator pursuant to EN 12729 Type BA.
Water that has flown through a system separator is no longer classified as drinking water.
High-pressure hoses, fixtures and couplings are important for the safety of the appliance. Only use high-pressure hoses, fixtures and couplings recommended by the manufacturer.
When disconnecting the supply or high pressure hose, hot water may leak from the connections after operation.

CAUTION

Mind the weight of the appliance when selecting the storage location and during transport (see technical data) to prevent accidents or injuries.

Working with detergent’

WARNING

This appliance was designed to be used with detergents which are supplied or recommended by the manufacturer. The use of other detergents or chemicals may compromise the safety of the appliance.
The improper use of detergents can cause severe injuries or toxication.
Store detergents away from the reach of children.

Safety Devices

CAUTION
Safety installations serve the protection of the user and may not be modified or bypassed.

Appliance switch

The appliance switch prevents unintentional operation of the appliance.

Lock trigger gun

The lock locks the lever of the trigger gun and prevents the accidental start of the device.

Auto-stop function

If the lever on the trigger gun is released, the pressure switch turns off the pump, the high-pressure jet stops. If the lever is pulled the pump is turned on again.

Dry running protection

The device shuts off automatically after 2 minutes of dry running so as to prevent damage to the high-pressure pump.

Personal protective equipment

CAUTION

Wear protective clothing and safety goggles to protect against splash back containing water or dirt.
During the use of high-pressure cleaners aerosols can develop. Inhaling aerosols can cause health damage.
- Depending on the application, completely shielded nozzles (e.g. surface cleaner) that significantly reduce the emission of aqueous aerosols can be used for highpressure cleaning.
- The use of such shielding is not possible with all applications.
- If the use of a completely shielded nozzle is not possible, a respirator of the category FFP 2 or the like should be used, depending on the environment to be cleaned.

Symbols on the machine

The high pressure jet must not be directed at persons, animals, live electrical equipment or at the appliance itself. Protect the appliance against frost.

The appliance must not be directly connected to the public drinking water network.

for cleaning machines, vehicles, buildings, tools, facades, terraces, gardening tools, etc. by means of a high pressure water jet (if necessary, with additional cleaning agents).
with accessories, replacement parts and cleaning agents approved by KÄRCHER. Please observe the information accompanying the cleaning agents.

Environmental protection

Old appliances contain valuable recyclable materials that should be recycled properly. Batteries and accumulators contain substances that must not enter the environment. Please dispose of old devices and batteries or accumulators in an environmentally friendly way.

Electrical and electronic devices often contain components which could potentially pose a danger to human health and the environment if handled or disposed of incorrectly. 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.

The packaging material can be recycled. Please arrange for the environmentally appropriate disposal of the packaging.

Cleaning operations which produce oily waste water, e.g. engine washes, underbody washes, may only be carried out using washing stations equipped with an oil separator.

Work with detergents must only be performed on liquid-tight work surfaces with a connection to the sewer system. Do not let release detergent into waters or earth.

Display	Meaning

Battery in storage
| Charging state of the battery pack while not in use.
Battery in use
| Remaining battery life of the bat- tery pack while in use.
Battery charging
| Remaining charging time of the battery pack during charging.
| Battery pack fully charged.
Error display
| Battery pack temperature outside the permitted values or disabled due to short-circuit (see Help in case of malfunctions).
| Battery pack defective and disa- bled for safety. Do not use the battery pack anymore and dis- pose of it properly.
