Mitsubishi FBP20 72V,80V – TR3500 Forklift Service Manual (99759-50100)

On a real floor this FBP20 is your basic electric counterbalance truck, moving pallets and racks where you'd normally run a sit-down electric. People grab this service manual when a code pops up, the truck loses drive or lift, or someone has to go deeper than swapping a contactor. Around my shop, this is what we pull when it's time to meter through the wiring, set pressures, or pull the drive unit apart without guessing.

What this manual helps you do

• Diagnose drive and lift problems on the 72V/80V system using wiring diagrams and step-by-step checks
• Trace and meter wiring and contactor circuits to find shorts, opens, and bad connections
• Follow teardown and reassembly of the drive unit, steering, brakes, and hydraulic components
• Adjust hydraulic pressures, limit switches, and mechanical linkages to spec after repairs
• Troubleshoot fault codes and performance issues in the traction and pump control systems

Who this is for

This is aimed at warehouse maintenance techs, independent forklift shops, dealer techs, and rental fleet mechanics who actually wrench on these trucks. If you only need basic operating instructions or safety info, you want the operator's handbook, not this service manual.

FAQ

Q: What format is it in and how readable are the diagrams?

A: You get 14 PDF files, scanned pages with no text search. They zoom and print fine, including wiring diagrams, but you'll scroll and read like a paper book.

Q: Will this cover my truck's serial number and variant?

A: It's for FBP20 72V/80V, TR3500, serials starting at E1BP2-82001 and up. If your plate matches that family, this is the right one.

Q: Is this the right document if I'm planning in-house repairs?

A: Yes, if you're doing real troubleshooting and component work. For parts ordering, you'd still want the separate parts catalog.

Bottom line: If your plate says FBP20 72V or 80V TR3500 in that serial range and you're doing your own repairs, this is the manual you want. If not, skip it.
