2.7.1 General
One of the first rules of troubleshooting is to first understand the normal operating
sequence of the machine (see Principle of Operation). Then carefully listen to the
key operator's description of the problem or complaint. Follow this by your own
visual observation. The cause of the problem can be determined by noting at
which point in the operating cycle the problem occurred. To pinpoint the problem
to a defective electrical component or mechanical part, use the Troubleshooting
Guide and the Electrical Schematic Diagram.
During any service call, it is a good practice to check the cable connections for fit
and alignment.
