Troubleshooting
Important:
Ensure that the operator safety mechanisms for the machine are connected and in proper
operating condition before you use the machine.
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
engine 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.
