5. Instruccions de funcionament
- Ajusteu el gruix de l'escuma: Use the top knob on the foam cannon to adjust the foam thickness. Turning it clockwise typically increases foam density, while counter-clockwise reduces it.
- Ajustar el patró de polvorització: The front nozzle can be rotated 360 degrees to change the spray pattern from a narrow stream to a wide fan. The V3.0 structure allows for smoother control.
- Aplicar escuma: Once connected and adjusted, activate your pressure washer and spray the foam onto your vehicle. Cover all surfaces evenly.
- Temps d'estada: Allow the foam to dwell on the vehicle surface for a few minutes to loosen dirt and grime. Do not let the foam dry on the surface.
- Esbandida: After the foam has worked, rinse the vehicle thoroughly with clean water using your pressure washer, starting from the top and working downwards.

6. Manteniment
- Esbandida després de l'ús: After each use, empty any remaining soap solution from the bottle. Fill the bottle with clean water and run it through the foam cannon for 30-60 seconds to flush out any soap residue. This prevents clogging.
- Clean Orifice Nozzle: Periodically check the orifice nozzle for blockages. If foam production is reduced, the nozzle may be clogged. Use a small pin or needle to clear any obstructions.
- Inspeccionar connexions: Regularly check all connections and O-rings for wear or damage. Replace worn parts to prevent leaks.
- Emmagatzematge: Store the foam cannon in a clean, dry place away from direct sunlight and extreme temperatures.
7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Weak or no foam production | Incorrect soap dilution, clogged orifice nozzle, insufficient pressure washer PSI, unsuitable shampoo. | Adjust soap-to-water ratio (1:9 recommended). Clean or replace orifice nozzle. Ensure pressure washer meets minimum PSI (1300 psi). Use a shampoo designed for foam cannons. |
| Fuites de les connexions | Loose connections, worn O-rings, damaged fittings. | Tighten all connections. Inspect and replace any worn or damaged O-rings. Ensure fittings are not cross-threaded. |
| Bottle tipping over easily | Unstable placement, external force. | The V3.0 bottle has an improved design for stability. Ensure it is placed on a flat, stable surface when not in use. |
Shampoo Suitability
The type of shampoo used significantly impacts foam quality. Always use shampoos designed to lather well in a foam cannon. Some shampoos, especially those intended for direct application without dilution or those with wax/iron remover properties, may not produce adequate foam.
