How do I flush out the main tank?

The main tank can be flushed out thoroughly by filling it with fresh water (and a cleaning agent if required) and then disposing of the water through the boom or main tank drains in a suitable area. Tank rinsing nozzles can be fitted to assist in cleaning. The tank rinsing nozzles operate under high pressure from the main pump and can be easily removed from the top of the tank for cleaning and inspection.
