Using the Pressure Washer and Nozzle Selection
The pressure washer comes with 5 quick-connect nozzles, each designed for specific cleaning tasks. Select the appropriate nozzle based on the surface and cleaning intensity required.

Figure 4: The five quick-connect nozzles, offering different spray patterns and intensities for various cleaning applications.
- 0° Red Nozzle (Pencil Jet): Most Abrasive. Delivers a concentrated, high-impact stream. Use for tough, localized stains on concrete, metal, or for removing cracks in pavement.

- 15° Yellow Nozzle (Chisel Tip): Medium Abrasive. Provides a 15-degree fan spray. Ideal for general cleaning of hard surfaces like concrete, asphalt, and brick.

- 25° Green Nozzle (Fan Spray): Less Abrasive. Offers a 25-degree fan spray. Suitable for general cleaning of wood decks, fences, and patios.

- 40° White Nozzle (Wide Fan Spray): Gentle. Produces a 40-degree wide fan spray. Best for delicate surfaces like vehicles, windows, and outdoor furniture.

- Black Soap Nozzle: Lowest Pressure. Used for applying detergent at low pressure. Activates the soap tank.

Always test the spray on an inconspicuous area first to avoid damage. Maintain a safe distance from the surface being cleaned.
