5.2 Using the Vario Power Spray (VPS) Wand

- Adjusting Pressure: Rotate the nozzle on the VPS wand to increase or decrease the water pressure.
- Detergent Application: For detergent application, rotate the VPS nozzle to the lowest pressure setting. Ensure the detergent tank (if applicable to your model) is filled with Karcher pressure washer detergent.
5.3 Using the DirtBlaster Spray Wand
The DirtBlaster spray wand provides a concentrated, rotating jet of water for maximum cleaning power, increasing effective pressure by up to 50%. Use this wand for tough dirt and grime on durable surfaces like concrete.
5.4 Cleaning Techniques
- Always test a small, inconspicuous area first to ensure the surface can withstand the pressure.
- Start cleaning from top to bottom on vertical surfaces to allow detergent to work effectively.
- Maintain a consistent distance from the surface for even cleaning.
