Operating Instructions

1. Build Pressure: Pump the handle up and down repeatedly until resistance is felt and the desired pressure is built up in the tank. The sprayer is designed to operate at 3 bar.
2. Adjust Nozzle: Rotate the nozzle at the end of the spray wand to adjust the spray pattern from a fine mist to a direct stream, depending on your application needs.
3. Begin Spraying: Press the trigger on the spray wand handle to begin spraying. Release the trigger to stop.
4. Maintain Pressure: If the spray pressure decreases during use, pump the handle again to re-pressurize the tank.
5. Release Pressure After Use: Once finished, always release any remaining pressure in the tank by pulling the pressure relief valve or by holding down the spray trigger until all pressure is dissipated.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your sprayer.

• Cleaning After Each Use:
  • Empty any remaining liquid from the tank.
  • Rinse the tank thoroughly with clean water.
  • Pump clean water through the hose and nozzle to flush out any residue.
  • Clean the nozzle and filter (if applicable) to prevent blockages.
• Storage: Store the clean and dry sprayer in a frost-free environment, away from direct sunlight. Ensure the pressure is released before storage.
• Seal Lubrication: Periodically inspect and lubricate the pump seals and O-rings with silicone grease to maintain a good seal and smooth operation.
