- the high-pressure cleaner 10 despite its compact design, in which the assembly 34 is installed below the heat exchanger 104, characterized by a high ease of maintenance.
- the user may remove the hood 118 of the housing 120 so that the high pressure cleaner 10 presents to the user substantially as shown in FIG.
- the upper part 19 forming a first appliance unit 134 of the high-pressure cleaning appliance 10 from the lower part 18 forming a second appliance unit 136 of the high-pressure cleaning appliance 10 it is possible to proceed as follows:
- the user can release the connecting elements 92 and 93 which connect the support plate 84 to the support elements 62 and 63, as well as the third connection element, not shown in the drawing, with which the support plate 84 is connected to the support element 66.
- the liquid discharge line 108 can be detached from the pump unit 42 without tools.
- the electrical lines, not shown in the drawing can be solved without tools.
- the fuel lines, also not shown in the drawing, for example, from the fuel pump 48, the heat exchanger 104 or the fuel tank 130 can be solved.
- the upper part 19 can be spaced apart relative to the lower part 18, for example by a user gripping the upper part 19 on the grip element 100.
- connection of the support means 80 is solved with the support means 60, in particular the non-positive connection of the support plate 84 with the support members 62, 63, 66 and 68 and also the positive connection of the profile bars 88 and 89 with the receptacles 70 and 73.
- positive connection of the lower edge 124 of the housing wall 116 is solved with the edge 126 on the chassis 20 and the positive connection of the support member 132 of the fuel tank 130 with the receptacle 76th
- the high-pressure cleaning device 10 substantially assume the relative arrangement shown in Figure 7 of the upper part 19 and the lower part 18 to each other.
- a formed below the support plate 84 and from this top side covered receiving space 138 is freely accessible to the user in this way.
- the assembly 34 is partially covered by the cover 52.
- the lower part 18 is thus substantially as shown in FIG. 5, the lower part 18 additionally additionally comprising the electrical devices 54 and 56.
- the user now freely accessible cover 52 can be solved by him in a simple manner, so that he has access to the complete assembly 34, their individual components and thus to numerous functional tions of the high-pressure cleaner 10 has. At these functional devices, the user can perform the required maintenance.
- the above-mentioned fuel lines, the electrical lines and a function of the liquid discharge line 108 engaging liquid discharge line or the same should be re-connected functionally.
- the assembly 34 may be retained on the support 60 and the heat exchanger 104 on the support 80.
- the high-pressure cleaning device 10 is characterized in that it can be mounted again in a simple manner. For this purpose, for example, in the reverse order to proceed as described above for separating the upper part 19 and the lower part 18 from each other.
