Nozzle Selection and Usage

- 15° Yellow Nozzle (Powerful Stain Removal): Provides a powerful, narrow spray for removing paint, grease, grime, oil, and cleaning concrete or boats.
- 25° Green Nozzle (Surface Cleaning): Offers a wider spray for general cleaning of decks, wood, fences, and siding.
- 40° White Nozzle (Light Dusting & Dirt Removal): Produces a wide, gentle spray suitable for delicate surfaces, automobiles, windows, and garden areas.
To change nozzles, pull back the collar on the quick-connect fitting, insert the desired nozzle, and release the collar to lock it in place. Always ensure the nozzle is securely attached before operating.

Foam Cannon Usage
The foam cannon is ideal for applying detergents or cleaning solutions for pre-treatment and deep cleaning, especially for vehicles. Fill the detergent bottle with your chosen cleaning solution. Attach the foam cannon to the spray gun. The cleaner will not pass through the pump, protecting the internal components.
