Safety instructions
Danger
- Never touch the mains plug and the socket with wet hands.
The appliance must not be used if the power cord or important parts of the appliance, e.g. high-pressure hoses, trigger gun or safety devices are damaged.
Check the power cord and mains plug for damage before every use. If the power cord is damaged, please arrange for it to be replaced immediately by an authorised repair agent or a skilled electrician
Check the high-pressure hose for damage before every use. Please arrange for the immediate replacement of a damaged high-pressure hose.
The appliance may not be used in areas where a risk of explosion is present.
If the appliance is used in hazardous areas (e.g. filling stations) the corresponding safety provisions must be observed.
High-pressure jets can be dangerous if improperly used. The jet must not be directed at persons, ani
mals, live electrical equipment or at the appliance itself.
The high-pressure jet must not be directed at other persons or directed by the user at him/herself to clean clothing or footwear.
- Never use the appliance to clean objects containing hazardous substances (e.g. asbestos).
Vehicle tyres or tyre valves are susceptible to damage from the high-pressure jet and may burst. The first indication of this is a discolouration of the tyre. Damaged vehicle tyres/tyre valves are highly dangerous. Ensure that a distance of at least 30~cm is observed when cleaning with the jet!
- Never draw in fluids containing solvents or undiluted acids and solvents! This includes petrol, paint thinner and heating oil. The spray mist thus generated is highly inflammable, explosive and poisonous. Do not use acetone, undiluted acids and solvents as they are damaging to the materials from which the appliance is made.
Warning
The mains plug and the coupling of an extension cable must be watertight and must never lay in the water.
- Unsuitable extension cables can be hazardous. Only use extension cables outdoors which have been approved for this purpose and labelled with a sufficient cable cross-section: 1 - 10 m: 1.5 mm²; 10 - 30 m: 2.5 mm²
Always fully unroll electrical cables from the cable drum.
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.
This appliance is not intended for use by persons with reduced physical, sensory or mental capabilities.
The appliance must not be operated by children or persons who have not been instructed accordingly. Children should be supervised to prevent them from playing with the appliance.
The operator must use the appliance correctly. When working with the appliance, he must consider the local conditions and pay due care and attention to other persons, in particular children, who are nearby.
- Do not use the appliance when there are other persons around unless they are also wearing safety equipment.
Wear protective clothing and safety goggles to protect against splash back containing water or dirt.
Caution
- Do not operate the appliance at temperatures below 0^ .
Observe a distance of at least 30 cm when using the jet to clean painted surfaces to avoid damaging paintwork.
Never leave the appliance unattended when it is in operation.
Make sure that the power cable or extension cables are not damaged by running over, pinching, dragging or similar. Protect the power cable from heat, oil, and sharp edges.
All current-conducting parts in the working area must be protected against jet water.
The appliance may only be connected to an electrical supply which has been installed in accordance with IEC 60364.
The appliance may only be connected to alternating current. The voltage must correspond with the type plate on the appliance.
The maximum tolerable mains impedance at the electrical contact point (see Technical Data) must not be exceeded.
For safety reasons, we recommend that you operate the appliance only via a earth-leakage circuit breaker (max. 30 mA). - 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.
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.

Screw the coupling unit (supplied) to the water connection on the appliance.
Push the water supply hose onto the
coupling unit, then connect it to the water supply.
Drawing in water from open reservoirs
This high-pressure cleaner is suited to work with the KÄRCHER suction hose with backflow valve (Optional accessory, order no. 4.440-238) to draw in surface water, e.g. from water butts or ponds (see specifications for max. suction height).
Fill the KÄRCHER suction hose with backflow valve with water, screw to water supply and hang into he water butt.
Separate the high pressure hose from the high pressure connection of the appliance.
Switch the appliance on "I/ON" and operate until the water exits the high-pressure connection without bubbles.
