– 6For connection values refer to technicalspecifications Connect the supply hose (minimumlength 7.5 m, minimum diameter 3/4“) tothe water connection point of the ma-chine and at the water supply point (fore.g. a tap).Note: The supply hose is not included.If you want to suck in water from an exter-nal vessel, the following modification isnecessary: Remove the water connections from thepump heads. Unscrew the upper supply hoses to theswimmer tanks and connect them to thepump heads. Connect suction hose (minimum diame-ter 3/4“) with filter (accessory) to thewater connection point.Until the pump sucked in water, you should: Set the pressure/quantity regulation tomaximum quantity. Close the dosing valve for the detergent. DangerNever suck in water from a drinking watercontainer. Never suck in liquids which con-tain solvents like lacquer thinner, petrol, oilor unfiltered water. The sealings within thedevice are not solvent resistant. The spraymist of solvents is highly inflammable, ex-plosive and poisonous.– For connection values, see technicaldata and type plate.– The electrical connections must bedone by an electrician according to IEC60364-1. DangerDanger of injury by electric shock.– Unsuitable extension cables can behazardous. Only use extension cablesoutdoors which have been approved forthis purpose and labelled with a suffi-cient cable cross section:– Always unwind extension lines com-pletely.– The plug and coupling of the extensioncable used must be watertight.CautionThe highest allowed net impedance at theelectrical connection point (refer to techni-cal data) is not to be exceeded. In case ofconfusion regarding the power impedancepresent on your connection, please contactyour utilities provider. DangerRisk of explosion!Do not spray flammable liquids. DangerRisk of injury! Never use the appliancewithout the spray lance attached. Checkand ensure proper fitting of the spray lanceprior to each use. The screw connection ofthe spray lance must be fingertight.CautionNever operate device with empty fuel tankThe fuel pump will otherwise be destroyed. WarningLong hours of using the appliance cancause circulation problems in the hands onaccount of vibrations.It is not possible to specify a generally validoperation time, since this depends on sev-eral factors:– Proneness to blood circulation deficien-cies (cold, numb fingers).– Low ambient temperature. Wear warmgloves to protect hands.– A firm grip impedes blood circulation.– Continuous operation is worse than anoperation interrupted by pauses.In case of regular, long-term operation ofthe device and in case of repeated occur-rence of the symptoms (e.g. cold, numb fin-gers) please consult a physician.Water connectionSuck in water from vesselPower connectionOperationSafety instructions22 EN
