Maintenance Tips
  • Always remove the battery before cleaning, nozzle changes, or maintenance to prevent accidental spray activation.
  • Flush the tank, hose, wand, and pump with clean water after every use to remove chemical residue and prevent clogging or seal damage.
  • Clean the in-tank filter screen regularly to maintain steady flow and reduce pump strain and battery drain.
  • Inspect and clean nozzles frequently; replace if spray pattern becomes uneven or blocked.
  • Check O-rings and seals on hose connections and wand for cracks or flattening; lubricate lightly with silicone grease.
  • Do not store chemicals inside the tank—always empty and dry the sprayer before storage to prevent corrosion and odor buildup.
  • Store indoors in a cool, dry place away from direct sunlight and freezing temperatures to protect plastic tank and electronics.
  • Wipe exterior surfaces with a damp cloth only; avoid solvents or pressure washing.
  • Keep battery terminals clean and dry for reliable power delivery and consistent pressure output (up to 350 PSI).
  • Remove battery during long-term storage and keep it at a moderate charge level for extended lifespan.
