– 3Quality requirements for water:ATTENTIONOnly clean water may be used as highpressure medium. Impurities will lead to in-creased wear and tear or formation of de-posits in the appliance and accessories.If recycled water is used, the following limitvalues must not be exceeded. DANGER– Do not use high pressure cleanerswhen there has been an oil spill; movethe appliance to another spot and avoidany sort of spark formation.– Do not store, spill or use fuel in the vi-cinity of open flames or appliances suchas ovens, boilers, water heaters, etc.that have an ignition flame or can gen-erate sparks.– Keep even mildly inflammable objectsand materials away from the silencer (atleast 2 m).– Do not start the engine without the si-lencer; check, clean and replace, if re-quired, the silencer at regular intervals.– Do not use the engine in forest, bushesor grassy areas without fitting a sparkreceiver at the exhaust.– Except for setting jobs, do not run theengine when the air filter is removed orthere is no cover over the suction sup-port.– Do not make any adjustments to theregulator springs, regulator bars or oth-er parts that can bring forth an increasein the engine speed.– Risk of burns! Do not touch hot silenc-ers, cylinders or radiator ribs.– Do not put hands or feet close to mov-ing or rotating parts.– Risk of poisoning! The appliance shouldnot be operated in closed rooms.– Please follow the national rules andregulations for fluid spray jets of the re-spective country.– Please follow the national rules andregulations for accident prevention ofthe respective country. Fluid spray jetsmust be tested regularly and the resultsof these tests must be documented inwriting.– The heating appliance of the machine isan ignition plant. All national laws andregulations about heating systems mustalso be followed.– The appliance/accessories must not bemodified. DANGERRisk of injury!– Only use original high-pressure hoses.– The high-pressure hose and the injec-tion system must be suitable for themaximum operating pressure given inthe Technical Data.– Avoid contact with chemicals.pH value 6,5...9,5electrical conductivity * Conductivityfresh water+1200 μS/cmsettleable solids ** < 0,5 mg/ltotal suspended solids *** < 50 mg/lHydrocarbons < 20 mg/lChloride < 300 mg/lSulphate < 240 mg/lCalcium < 200 mg/lTotal hardness < 28 °dH< 50 °TH< 500 ppm (mgCaCO3/l)Iron < 0,5 mg/lManganese < 0,05 mg/lCopper < 2 mg/lActive chloride < 0,3 mg/lfree of bad odours* Maximum total 2000 μS/cm** Test volume 1 l, settling time 30 min*** no abrasive substancesSafety instructionsGeneral notes on safetyHigh pressure hose22 EN
