– 4 WarningRisk of injury on account of unsuitable ac-cessories. Only use accessories approvedfor the working pressure of the appliance(see "Specifications").Only install accessories when the appli-ance is switched off. Install the rotating coupling for the connec-tion of the high pressure hose to the gun.(not with HD 16/15-4 Cage) Connect high pressure hose and spraypipe to the hand spray gun. Tighten the screw connection of thespray lance finger tight. Insert high pressure nozzle into cover-ing nut Install covering nut and tighten firmly Connect the high pressure hose to thehigh pressure connection point of themachine.– For connection values refer to technicalspecifications– The electrical connections must bedone by an electrician according to IEC60364-1. WarningThe highest allowed net impedance at theelectrical connection point (refer to techni-cal data) is not to be exceeded.In case of confusion regarding the powerimpedance present on your connection,please contact your utilities provider. Danger– Check whether the voltage indicated onthe type plate corresponds to the volt-age of the socket.– Unsuitable extension cables can behazardous. Only use extension cablesoutdoors which have been approved forthis purpose and labelled with a suffi-cient cable cross section:1 - 10 m: 4 mm210 - 30 m: 6 mm2 WarningObserve regulations of water supplier.According to the applicable regula-tions, the appliance must never beused on the drinking water supplywithout a system separator.
