NOTE: After carefully checking the previous steps, attempt to start the engine. If it does not start, contact your authorized Exmark service dealer.
ENGINE TROUBLESHOOTING
When a problem occurs, do not overlook the simple causes. For example, starting problems could be caused by an empty fuel tank, key switch not "ON" etc. The following tables list some common causes of troubles.
Do not attempt to service or replace major items or any items that call for special timing or adjustment procedures (governor, valves, etc.). Have this work done by your Engine Service Dealer.
