SECTION III USE
Electronic control of engine cooling system
The engine cooling system is controlled by an electronic control unit.
The control unit uses a temperature sensor to switch the cooling fan on
when the engine reaches 92°C and to switch it back off again when
temperature drops below 90°C.
Important: The operator should be able to hear the fan working.
