Operating Instructions
Operating the Kärcher T-Racer T 5 is straightforward:
- Surface Preparation:
Clear the area to be cleaned of any loose debris, furniture, or obstacles.
- Adjust Nozzle Distance:
Rotate the grey knob on top of the T-Racer T 5 to adjust the distance of the nozzles from the cleaning surface. Turn towards "HARD" for robust surfaces like stone or concrete, and towards "SOFT" for delicate surfaces like wood or painted areas. This adjustment helps prevent damage and optimizes cleaning performance.
