Troubleshooting Insights

EC Motor:

• Engine speed remains at idle even when the control dial is adjusted.
• Difficulty in starting the engine, potential for stalling above specified speeds.
• Uncontrollable engine behavior at speeds below specification, unable to stop with key switch.

EC Sensor:

• Errors in setting are rare, but when on the lower side, engine speed runs slower than normal.
• Setting errors on the upper side prevent stalling through a constant maximum position.
• Fluctuations in engine speed upon starting and occasional starting difficulties.
