Toyota Pallet Truck Service Manual How To Use This Manual Manual Design 00700-CL398-07, Issued: 9 August 2007 1-3 Manual Design The Toyota Pallet Truck Service Manual is designed with the following objectives in mind: • Provide technical coverage for expected levels of user expertise • Anticipate your needs and reduce your decisions regarding maintenance • Reduce page flipping thru a “one-stop shopping” approach The two-line running page header at the top of each page tells you: • Name of the manual (Toyota Pallet Truck Service Manual) • Current section title (for example, this page How to Use This Manual) • Current topic (for example, this page Manual Design) We suggest you get in the habit of turning to the START page first when you use this manual. • The START page asks a few questions to guide you to the correct section. How to Use This Manual explains the manual format and contains the 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 theory of operation information. Planned Maintenance outlines the recommended schedule of preventive services to keep your truck working most efficiently. Troubleshooting is a set of fault, caution, and error codes, charts and tables designed to take you from a symptom to a specific sequence of actions in order to isolate a failing component. • The chart “Traction Power Amplifier Flash Codes” on page 5-27 will guide you thru the flash codes displayed on the LED’s installed on the TA. • The section “Caution and Error Codes” on page 5-33 defines the various codes displayed on the operator display. • The chart “TS1: START TROUBLESHOOTING” on page 5-29 will guide you to the symptom chart you need. • When you’re familiar with the symptoms listed, you may simply look up the symptom from the “Troubleshooting” on page 5-29. • As you work with a troubleshooting chart, code, or table, you may be instructed to test various electrical connector pins. The pinout matrix chart lists information on functions and normal voltages of terminals and harness connector pins. See “Pinout Matrix” on page 5-69. • When you complete a troubleshooting procedure, perform the steps in the “END1: End of Troubleshooting Procedure” on page 5-31. Component Procedures gives step-by-step procedures for testing, removal, installation, and adjustment of individual truck components. Components are listed in an order that considers: • Frequency of attention • Physical attachment (for example, remove the brake before the traction motor) • Functional relation (for example, traction motor and drive unit 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” on page 6-2. • Find the component in the “Component Locator Photos” on page 6-5. • Look up component name in the “Index”. Appendix contains reference information such as torque values, lubricants, and schematics. Index lists subjects alphabetically.
