Maintenance of a street sweeper includes several essential steps. In addition to cleaning brushes, filters and emptying the dirt container after each use, periodically checking for brush wear and replacing them in a timely manner is important. Also regularly check fluids such as oil, hydraulic fluid and coolant, and refill as needed. Ensure proper tire pressure and lubricate moving parts to keep the machine running smoothly. Finally, perform regular engine inspections and check the operation of lights and electrical components.
