How to use

Attach the DB 120 nozzle to a compatible K 2 or K 3 Kärcher pressure washer according to the washer's accessory fitting instructions. Operate the pressure washer at the appropriate pressure setting for the surface being cleaned, maintaining a safe distance and sweeping the rotating jet across the area to gradually remove dirt and biological growth. Adjust approach angle and distance as needed to avoid surface damage on softer materials.

Recommendations

Use personal protective equipment such as eye protection and gloves. Test the nozzle on a small inconspicuous area before full cleaning. Avoid directing the jet at people, animals, electrical components or fragile surfaces. For best results on heavily soiled areas, combine mechanical cleaning with suitable cleaning agents recommended for pressure washer use and follow manufacturer guidance.
