How to Use This Manual explains the manual format and design and contains the Table of Contents and START page. Safety explains warning and caution notes, general safety rules and safety rules for batteries, static, jacking, and welding. Systems Overview includes truck specifications and functional overview of the major systems.

Scheduled Maintenance outlines the recommended schedule of preventive services to keep your truck working most efficiently.
Troubleshooting is a set of “decision-tree” charts designed to take you from a symptom to a specific sequence of tests in order to isolate a failing component. The START TROUBLESHOOTING chart (on page 5-20) will guide you to the individual troubleshooting symptom chart you need.

Once you’re familiar with the symptoms listed, you may instead simply find the symptom chart from the List of Troubleshooting Charts (page 5- 19). Manual Design Index lists subjects alphabetically. When you complete a troubleshooting procedure, be sure to follow the steps in End of Troubleshooting Chart END- 1 (page 5-23).
Electrical Codes and Tests contains detailed description of the software modes of operation and information about electrical error codes and diagnostic tests under the control of the system firmware.
Component Procedures gives step-by-step procedures for testing, removal, installation, and adjustment of individual truck components. Components are listed in an order which considers: Frequency of attention Physical attachment (e.g., brake must be removed before drive motor) Functional relation (e.g., carriage and mast components are grouped together) To find a component procedure, you may use one of three methods: Look up the component name in the List of Component Procedures (page 7- 1). Find the component in the Component Locators (page 7-3). Look up the component name in the maintenance manual Index (10- 1).
Theory of Operation gives detailed theory of operation information for all major systems. Appendix contains reference information such as torque values, lubricants, and schematics
