General Troubleshooting Information
Visual inspections are the first steps in order to troubleshoot a problem. When the visual inspections are complete and the problem is not fully understood, perform operational checks. After visual inspections and operational checks are complete and the problem is not fully understood, perform test procedures. These procedures will help identify system problems. These procedures are located in the Testing and Adjusting module for your machine.
For the locations of your individual system components, refer to the Systems Operation module for your machine.
