5. HOW TO USE THE TROUBLESHOOTING CHARTS
Troubleshooting is divided into mechanical, hydraulic, and brake sections. An overall fault index is located at the beginning of
the troubleshooting procedures and individual indexes are located at the beginning of each troubleshooting part. The fault
index lists common problems that you may have with the ATLAS and the page number where each can be found.
Troubleshooting procedures are divided into logic tree pages and test pages. A logic tree page is always a left-hand page facing
the test page on the right. The logic tree page provides the sequence of steps required to isolate a fault to a failed component.
All critical information for decision making is on the left-hand page.
A test page is always a right-hand page facing the logic tree page on the left. The test provides detailed instructions for testing
the first component listed in the POSSIBLE PROBLEMS box. This test will also provide an answer for the question in the
middle column. Note the arrow connecting the test on the right-hand page to the REASON FOR QUESTION. When possible,
illustrations are included to provide visual details. Warnings, cautions, and notes contain additional information for testing.
Please refer to Introduction to Logic Tree Troubleshooting (Para 2-6) for additional troubleshooting instructions.
