Troubleshooting

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 adjustments procedures (such as valves, governor, etc.). Have
this work done by your Engine Service Dealer.
Note: When disconnecting electrical connectors Do Not pull on the wires to separate the connectors.
