Maintenance Tips
  • Always prime before operation: Ensure proper priming with compatible fluid to prevent dry-start damage.
  • Flush after each use: Clean thoroughly with water or approved solvent to prevent paint buildup and internal clogging.
  • Inspect inlet filter regularly: Clean or replace to maintain steady flow and protect pump components.
  • Check seals and packings: Replace worn seals early to avoid leaks and pressure loss.
  • Avoid dry running: Never operate without fluid to prevent rapid internal wear.
  • Monitor spray pressure: Address pulsation or reduced output promptly to prevent long-term damage.
  • Lubricate as recommended: Use approved lubricant on moving parts to reduce friction and extend service life.
  • Store properly: Keep in a dry, frost-free environment to protect internal components and prevent corrosion.
