Safety Information
Always read and understand all safety warnings and instructions before using the foam cannon. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
- Always wear appropriate personal protective equipment, including eye protection, when operating the pressure washer and foam cannon.
- Ensure the pressure washer is turned off and disconnected from the power source before attaching or detaching the foam cannon.
- Do not direct the spray at people, pets, or electrical devices.
- Use only detergents specifically designed for pressure washers and foam cannons.
- Keep children and bystanders away from the work area.
Setup
- Prepare Detergent Solution: Fill the 34 fl oz heavy-duty plastic bottle with your preferred pressure washer detergent. The bottle features fluid ounce and milliliter markings for accurate mixing.
- Attach Foam Cannon: Connect the foam cannon to your pressure washer's spray wand using the 1/4" quick connect inlet. Ensure it is securely fastened. The foam cannon is compatible with most pressure washers up to 3000 PSI.

Operating Instructions
- Adjust Detergent Dial: Use the detergent dial at the top of the foam cannon to control the soap-to-water ratio. Turning the dial allows you to adjust the thickness of the foam produced.
- Adjust Spray Nozzle: The spray nozzle adjusts with a twist, allowing you to change the spray pattern from a pinpoint jet to a wide-angle fan spray.
- Apply Foam: Once adjusted, activate your pressure washer and begin applying the foam to the desired surface. The high-powered foamer covers gunk, grease, and grime with a thick lather.
- Rinse: After allowing the foam to dwell and break down dirt, rinse the surface thoroughly with clean water using your pressure washer or a hose.
