a)When the engine is running and the buzzer emits a continuous beep, the buzzer is warning the user that the engine is overheating. Perform the following steps.

1.Disengage the mower blades, and idle down the engine.

2.Look at the temperature gauge to determine if temperature continues to increase. If it does, turn the unit off and allow the engine and engine components to cool.

3.Check the coolant level. If necessary fill with coolant as described in Section 4.1.2.

4.Remove any debris on or around the radiator that may restrict airflow.

5.Check to see if the water pump/alternator belt is intact. If belt is missing, do not run unit, as unit can overheat and damage the engine. See Engine Service Dealer.

b)When the engine is running and the buzzer emits intermittent beeps, the buzzer is warning the user that the engine oil pressure is low. Perform the following steps.
