The appliance must not be used if the power cord or important parts of the ap- pliance, e.g. high-pressure hoses, trig- ger 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 dam- age 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 ar- eas (e.g. filling stations) the corre- sponding safety provisions must be observed. High-pressure jets can be dangerous if improperly used. The jet must not be di- rected at persons, animals, live electri- cal equipment or at the appliance itself. The high-pressure jet must not be di- rected at other persons or directed by the user at him/herself to clean clothing or footwear. Never use the appliance to clean ob- jects containing hazardous substances (e.g. asbestos). Vehicle tyres or tyre valves are suscep- tible to damage from the high-pressure jet and may burst. The first indication of this is a discolouration of the tyre. Dam- aged vehicle tyres/tyre valves are high- ly dangerous. Ensure that a distance of at least 30 cm is observed when clean- ing with the jet! Risk of explosion! Do not spray flammable liquids. Never draw in fluids containing solvents or undiluted acids and solvents! This in- cludes petrol, paint thinner and heating oil. The spray mist thus generated is highly inflammable, explosive and poi- sonous. Do not use acetone, undiluted acids and solvents as they are damag- ing to the materials from which the ap- pliance is made. 몇 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 suffi- cient cable cross-section:
