RELATIONSHIP BETWEEN MACHINE TROUBLE SYMPTOMS AND RELATED PARTS EXTRACT:
Symptoms in machine operation when trouble occurs..

EC Motor

• Even if engine control dial is turned, engine speed does not increase from slow idle speed.
• Engine start may be difficult though starter rotates. • Engine will stall if discontinuity occurs in EC motor while engine is running at more than a specified speed.
• Engine will become uncontrollable if discontinuity occurs in EC motor while engine is running at lower than a specified speed. Engine cannot be stopped with key switch.

EC Sensor

• Error in setting will seldom occur so that change in machine operation will not be noticed.
• In case error is set on lower side, engine speed changes but runs slower than normal through the full range when engine control dial is turned. (Note: In case error is set on upper side, EC motor is driven so that it runs faster than the control range. However, motor, a worm gear type, holds governor lever at maximum constant position, preventing engine stall. When engine control dial is turned to minimum speed position, governor lever is returned to idle position.) • When starting engine, engine speed fluctuates.
• Starting engine is occasionally difficult.
