How to use

Attach the dirt blaster to a compatible Kärcher K4 or K5 pressure washer via the bayonet connection until it locks into place. Operate the pressure washer according to the machine’s instructions and hold the nozzle at a safe distance from the surface to be cleaned while moving steadily to cover the area. Adjust the working distance to control cleaning intensity and avoid concentrating the jet on one spot for too long.

Usage recommendations

Use appropriate personal protective equipment and follow the pressure washer manufacturer’s safety guidelines. Test the nozzle on a small, inconspicuous area first to ensure the surface tolerates the rotating point jet and the selected working distance.
