Maintenance
Regular maintenance ensures the longevity and optimal performance of your undercarriage cleaner:
- Clean Nozzles: If the spray pattern becomes irregular or weak, the nozzles may be blocked. Remove the nozzles and clean them with a needle or a thin wire, then rinse with fresh water.

- Check Connections: Periodically check all quick-connect fittings and threaded connections for tightness. Tighten any loose connections to prevent leaks.
