High speed ESG (Electronic Safety Governor)
High speed ESG is a device to prevent over revolution of the engine. If the load to the engine becomes light for
some reason, it runs at a higher speed than the usual. In such the case, the buzzer sounds and the ESG is
activated not to ignite the spark plug. Therefore, the engine speed varies and is controlled following specified
engine speed.
