Operation
- Wet the Surface: Before applying foam, wet the surface to be cleaned (e.g., car body) with plain water using your pressure washer.
- Adjust Foam Density:
- Locate the knob on the top of the foam cannon.
- Turn the knob towards the “–” sign to decrease water flow and increase detergent concentration, resulting in thicker foam for stubborn stains.
- Turn the knob towards the “+” sign to increase water flow and decrease detergent concentration, resulting in thinner foam for quick cleaning.
- Adjust Spray Angle:
- Rotate the front lance of the foam cannon to adjust the spray pattern from a narrow stream to a wide fan.
- Apply Foam: Once adjustments are made, activate your pressure washer and spray the foam evenly over the desired surface.
- Rinse: After allowing the foam to dwell as recommended by your cleaning solution, rinse the surface thoroughly with clean water using your pressure washer.
