– 2– The operating elements for the cleaningprocess are yellow.– The controls for the maintenance andservice are light gray.The appliance was developped specificallyfor working in areas with risks of explosion(zone 1 and zone 2).Use this high pressure cleaner exclusivelyfor:– to clean machines, vehicles, buildings,containers and tools, which are exclu-sively permitted for cleaning using ahigh-pressure cleaner.– with accessories and spare parts ap-proved by Kärcher.– It is wrong and therefore prohibited isthe cleaning of humans and animals.There is a high risk of injury due to thehigh pressure jet.– It is wrong and therefore prohibited iscleaning loose parts. These can getthrown off due to the high pressure jetand can cause damage to persons orother parts of the plant.– The appliance should only be operatedwith water.– If water is used for cleaning, protect theappliance from frost to prevent damag-es by freezing water.High-pressure jets can be dan-gerous if improperly used. Thejet may not be directed at per-sons, animals, live electrical equipment orat the appliance itself.– Please follow the national rules andregulations for fuel spray jets of the re-spective country.– Please follow the national rules andregulations for accident prevention ofthe respective country. Fuel spray jetsmust be tested regularly and the resultsof these tests must be documented inwriting.1 The pump must only be used in zonesthat correspond to the ignition protec-tion type on the typeplate.2 The pump must be grounded electro-statically. The ground must be conduc-tive.3 The pump must only be operated afterits been ventilated.4 Never draw in fluids containing solventsor undiluted acids and solvents! This in-cludes petrol, paint thinner and heatingoil. The spray mist thus generated ishighly inflammable, explosive and poi-sonous. Do not use acetone, undilutedacids and solvents as they are aggres-sive towards the materials from whichthe appliance is made.5 The infeed temperature of the cleaningliquid water with detergents must notmust not exceed 50 °C.6 The pump must be checked regularlyfor flawless condition and function afteran appropriate operating period (amongothers, bearings for wear, pump forleaks). If applicable, a repair needs tobe conducted.7 The pump must only be used withcleaning liquids, whose affect on thematerials is not damaging.8 Hoses must be conductive (electrostat-ically) (resistance R < 10 6 Ohm).Use only original parts.9 Please follow the national rules andregulations of the respective country.Safety devices serve to protect the userand must not be rendered in operational ortheir functions bypassed.Colour codingProper useSymbols on the machineSafety instructionsSpecial conditions in the Ex areaSafety Devices15EN
