• Shutdown may be due to low fuel level
  Fix: Check for a low fuel or low coolant level condition. Add coolant at the pressure cap if it is not completely full. Add coolant to the recovery tank to bring the level up to the appropriate mark.
• Shutdown may be due to low coolant level in the radiator
  Cause: Low coolant level in the radiator

• High Water Temperature
  Cause: Engine coolant temperature exceeds 230_F (110_C)
• Generator set shuts down automatically
