Unscrew the bottle from the brass unit. Fill the wide-mouth bottle with your desired car wash soap or cleaning solution and water mixture according to the solution's instructions. The wide opening facilitates easy filling and reduces spills.

Choose the appropriate connector (M22 or 1/4 Inch Quick Connector) for your pressure washer. Attach the chosen connector to the foam cannon's inlet. Then, connect the foam cannon assembly to your pressure washer gun. Ensure a tight and leak-free connection.
Operating Instructions
- Adjust Spray Pattern:
Rotate the front nozzle of the foam cannon to adjust the spray pattern. You can switch between a wide fan spray for covering large areas and a narrow stream for targeted cleaning. The nozzle allows for 360-degree adjustment.

Use the top control knob to regulate the foam thickness. Turning the knob clockwise generally increases foam density, while turning it counter-clockwise reduces it. Experiment to find the desired foam consistency for your cleaning task.

Once connected and adjusted, activate your pressure washer. Point the foam cannon at the surface to be cleaned and spray an even layer of thick foam. Allow the foam to dwell for a few minutes to loosen dirt and grime, as recommended by your cleaning solution's instructions.

After the foam has worked, rinse the surface thoroughly with clean water using your pressure washer (without the foam cannon attached) or a standard hose.
- Multiple Usages:
The DANCINGBOAR Foam Cannon is suitable for various cleaning tasks, including vehicle washing, motorcycle cleaning, driveway cleaning, patio cleaning, and siding cleaning.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your foam cannon:
- After Each Use:
After each cleaning session, empty any remaining solution from the bottle. Fill the bottle with clean water and spray for 15-20 seconds to flush out any soap residue from the internal components. This prevents clogging and corrosion.
- Clean the Filter:
The foam cannon includes a mesh filter at the end of the suction tube to prevent impurities from entering the system. Regularly inspect and clean this filter to ensure unobstructed flow.

If foam production decreases or becomes inconsistent, the orifice may be partially clogged. Use the provided cleaning needle to clear any blockages. A spare 1.1mm orifice is included for finer foam production or as a replacement.
- Storage:
Store the foam cannon in a clean, dry place, away from direct sunlight and extreme temperatures. Ensure it is thoroughly cleaned and dry before storage.
