This official 513-page OEM PDF publication (P/N 00700-CL220), issued 10/01/98, covers the 1998 Toyota Reach 6BRU18, 6BRU23, 6BDRU15, 6BSU20, and 6BSU25 electric lift trucks. It documents electrical, hydraulic, and mechanical specifications for both 24V and 36V platform builds.

• Features 38 diagnostic troubleshooting flowcharts for electrical and hydraulic systems
• Includes specific testing data for lift pump operation, travel systems, and reach/retract functions to help plan your next repair
• Provides comprehensive lubrication equivalency charts and metric/standard conversion data
• Detailed electrical connector locator charts for all control boards and motors
• The only technical reference documenting the unique 24V pulsing logic for 36V lift components
• Outlines component procedures for the steer controller, traction power amplifier, lift power amplifier, caster assembly, contactor tips, motor brushes, deadman pedal, and staging cylinders
• Explains software functions and diagnostics including Analyzer mode, Calibrate mode, Configure mode, Tuning mode, Self-diagnosis mode, passwords, brush wear warning, and the shorts to frame test

Manual Contents and Workshop Benefits

Getting these reach trucks back on the warehouse floor requires accurate specifications. The document opens with critical safety protocols. You will find guidelines on battery handling, jacking safety, and static-discharge mitigation for sensitive electronic control cards. Keep in mind that working on high-voltage industrial equipment requires specialized training; always consult a certified technician before servicing these electrical systems to ensure a safe working environment.

Following the safety section, the text defines the vehicle layout. It details the integration between the tractor section, mast assembly, and reach-mechanism components. By referencing the exact pinout values and diagnostic flowcharts, your shop can accurately trace voltage drops across the electrical system, preventing the unnecessary and expensive replacement of perfectly functioning control boards. Furthermore, step-by-step procedures for adjusting the caster assembly, separating the lift pump and motor, and performing the shorts to frame test allow you to safely bypass costly external service calls. A major focus is placed on scheduled maintenance intervals. These range from daily checks to biennial service requirements. The manual outlines specific lubricants and inspection points for the drive unit, hydraulic system, and overhead guard mounting. Need to prep a truck for a freezer application? You get detailed guidance on cold storage conditioning, specifying fluid requirements for various temperature environments.

Technical Specifications and Diagnostics

Troubleshooting segments utilize a straightforward decision-tree structure. This allows you to efficiently isolate faults within the traction and hydraulic circuits during the diagnostic phase of a repair. To support your visual inspections, the documentation includes wiring diagrams, electrical schematics, hydraulic schematics, component location photos, standard torque charts, metric torque charts, and decimal equivalent charts, alongside a comprehensive electrical connector locator mapping pinouts for the tractor interface card and lift power amplifiers.

Essential calibration data is provided throughout. For instance, the hydraulic pressure relief valve is set between 1900–2200 psi for standard operations. Intake valve clearance specifications for the hydraulic system sit in the appendix. Finally, magneto pick-up coil resistance for the steer tachometer is fully documented to ensure accurate steering controller communication.
