The Technical manuals are divided in two parts: Repair and Operation and Tests.
-Repair sections tell how to repair the components.
-Operation and tests sections help you identify the majority of routine failures quickly.
Information is organized in groups for the various components requiring service instruction. At the beginning of each group are summary listings of all applicable essential tools, service equipment and tools, other materials needed to do the job, service parts kits, specifications, wear tolerances, and torque values. Technical Manuals are concise guides for specific machines. They are on-the-job guides containing only the vital information needed for diagnosis, analysis, testing and repair.
