Mitsubishi FB20AN Forklift Service Manual (640902-EN-A1)

A Mitsubishi FB20AN is an electric counterbalanced forklift you'll see working docks, warehouses, and production areas. The service manual is what I'd pull when the truck is faulting, a drive unit sounds wrong, or hydraulics start doing something weird. Around my shop, this is the book you want when you're past basic checks and you need wiring diagrams, adjustment specs, and step-by-step teardown info to get it fixed over a weekend.

What this manual helps you do

• Diagnose drive, lift, and steering problems using step-by-step checks and fault code information for the FB20AN.
• Trace, check, and repair wiring and connectors using the electric schematics and harness layouts.
• Follow procedures to remove, rebuild, and reinstall traction motors, hydraulic pumps, and major mechanical assemblies.
• Adjust brakes, steering, and hydraulic valves to the right settings after repair work.

FAQ

Q: What format is it in, and can I search it and read the wiring diagrams clearly?

A: It's a set of 23 PDF files with a real text layer, so you can search and copy text. Wiring diagrams are in the PDFs as section files.

Q: How do I know it matches my exact truck?

A: It's written for the Mitsubishi FB20AN electric counterbalance. For absolute certainty, match the model on your data plate to "FB20AN" and confirm with your dealer if your serial is a rare variant.

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

A: Yes. This is the workshop-level service manual, not parts or operator info, and it's what you'd use for real repair work on an FB20AN.

Bottom line: If your truck is an FB20AN and you're doing your own repairs, this is the right manual. If your model code is different, stop and verify before you buy.
