Troubleshooting

Important: It is essential that all operator safety mechanisms be connected and in proper operating
condition prior to use.
When a problem occurs, do not overlook the simple causes. For example: starting problems could be caused
by an empty fuel tank.

items or any items that call for special timing of adjustments procedures (such as valves, governor, etc.). Have
