Maintenance Tips
- Flush the AR45 diaphragm pump, hoses, and tank system with clean water after every use to prevent chemical (bleach/surfactant) crystallization and internal damage
- Never leave softwash chemicals sitting in the system—drain and rinse immediately after operation to protect valves and diaphragms
- Inspect and clean inlet filter/strainer regularly to prevent debris from restricting flow or damaging the pump head
- Check oil level and condition in the 6.5 HP Vanguard engine and follow scheduled oil changes for consistent starting and power delivery
- Keep air filter clean to maintain proper combustion, especially in dusty job-site environments
- Inspect AR45 pump fittings, pulse dampener, and hose connections for leaks or chemical seepage before each use
- Avoid dry-running the pump—always ensure liquid supply is primed before engaging the system
- Use only compatible softwash nozzles and tips to maintain correct low-pressure, high-volume output (300 PSI / 11.5 GPM system design)
- Store the skid unit in a dry, shaded area to prevent corrosion on frame, pump manifold, and engine components
- Winterize system in freezing conditions by fully draining all water lines, pump, and hoses to prevent cracking
- Periodically check battery (electric start system) terminals and charge level for reliable ignition performance
