The operation of the front and rear pump and motor groups, (5) and (16), are similar. Water pump (20) turns when electric motor (19) is activated. Water flows from the corresponding tank through inlet water line (21) to water pump (20). Water pump (20) creates pressure and the water flows through outlet water line (22) to the corresponding spraybar. High pressure shut down switch (23) regulates the water pressure to the spraybars by turning electric motor (19) on and off.Spray Bars And Nozzles

See "Spray Nozzle Adjustment" in the Testing And Adjusting section of this module.The front spraybar (8) is equipped with seven spray nozzles. The rear spraybar (14) is equipped with four spray nozzles. The nozzles can be taken apart and cleaned by hand (no tools needed).Circuit Functions
