For my new kraenzle HDR I bought a suitable used foam lance at ebay in order to be able to foam the car properly. Now I have the following problem: with mounted foam lance I have no steady pressure…. Sometimes more times less fluctuating (heart and see also on the manometer). The threads are all tight; and the HDR otherwise works perfectly (with normal or dryfraeser lance). So must lie on the foam lance. Can someone give me a n Tip what I can do, or is the part defect? Other question: in the case of kranzle detergents (and others) various evaporation conditions are given for different applications. Think this refers to the mixture in the cleaning tank(-container),or? I mean by the foam lance also additional water is consumed = the cleaning agent still further evaporates…. MfG Imsi
