g)Check for corrosion at all wiring connections. Even minor corrosion may cause a faulty connection. Clean connector terminals thoroughly with electrical contact cleaner; apply dielectric grease and reconnect.
NOTE: When disconnecting electrical connectors DO NOT pull on the wires to separate the connectors.
NOTE: After carefully checking the above steps, attempt to start the engine. If it does not start, contact your authorized Exmark service dealer.
IMPORTANT: It is essential that all operator safety mechanisms be connected and in proper operating condition prior to mower use.
When a problem occurs, do not overlook the simple causes. For example, starting problems could be caused by an empty fuel tank.
The following table lists some of the common causes of trouble. Do not attempt to service or replace major items or any items that call for special timing of adjustment procedures (such as valves, governor, etc.). Have this work done by your Engine Service Dealer.

a)When the engine is not running and the ignition switch is turned to the ON position, the buzzer emits intermittent beeps. The intermittent beeps remind the user that the switch is ON and the hourmeter is running. A switch left ON could also drain the battery.
b)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.
