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 be controlled under 6300rpm.
Remedy
1.
Reduce the throttle to less than half
opening, and move to safe place
quickly, and stop the engine.
Check the propeller for bent or dam-
aged blades.
Consult an authorized dealer if engine
shows the same result even after
replacing propeller with new one.
2.
Move to safe place quickly, and stop
the engine.
Check the engine oil level, and add
engine oil if necessary.
