Maintenance

Regular maintenance will prolong the life and efficiency of your sprayer.

  1. Clean After Each Use: After each use, empty any remaining liquid from the tank. Rinse the tank thoroughly with clean water and a mild soap solution. Operate the sprayer with clean water for a few minutes to flush the pump, hose, and wand. This prevents chemical buildup and clogs.
  2. Nozzle Care: Remove nozzles and clean them separately. Use a small brush or pin to clear any blockages.
  3. Battery Storage: Remove the battery from the adapter and store it in a cool, dry place. Ensure the battery is charged before long-term storage.
  4. General Cleaning: Wipe down the exterior of the sprayer with a damp cloth.
