4. Operating Instructions
Once assembled and filled, operate the sprayer as follows:
- Connect Water: Ensure your garden hose is connected to a water source and the water supply is turned on.
- Adjust Ratio: Set the mixing ratio dial on the sprayer head to your desired concentration. Refer to the chemical manufacturer's instructions for recommended dilution rates.
- Activate Spray: Squeeze the trigger on the sprayer handle to begin spraying. The unit will automatically mix the chemical solution with water at the selected ratio.
- Foam or Stream: The foaming attachment provides a wide fan spray for broad coverage. To achieve a solid stream without foam, remove the foaming attachment.
- Rinsing: To rinse with plain water, detach the chemical reservoir from the sprayer head. The sprayer handle can then be used to deliver a stream of water directly from the hose.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Foamaster Sprayer:
- Rinse After Use: After each use, empty any remaining chemical solution from the reservoir. Fill the reservoir with clean water and spray until all chemical residue is flushed from the system. This prevents clogging and corrosion.
- Clean Reservoir: Periodically clean the inside of the chemical reservoir with warm, soapy water. Rinse thoroughly.
- Inspect Nozzle: Check the foaming attachment and nozzle for any blockages or damage. Clean as needed.
- Storage: Store the sprayer in a cool, dry place, away from direct sunlight and freezing temperatures. Ensure the reservoir is empty and clean before storage.

If you encounter issues with your Foamaster Sprayer, refer to the following common problems and solutions:
- No Foam or Low Foam:
- Check if the chemical solution is sufficiently concentrated for foaming.
- Ensure adequate water pressure from your hose.
- Verify that the foaming attachment is securely in place and not clogged.
- Confirm the ratio dial is set correctly.
- Leaking from Connections:
- Tighten all connections, including the hose connection and the reservoir attachment.
- Inspect O-rings and gaskets for wear or damage. Replace if necessary.
- No Solution Dispensed:
- Ensure the chemical reservoir contains solution.
