Mitsubishi FB20ANT Forklift Service Manual (640902-EN-A1)

On the floor this FB20ANT is a small electric counterbalanced forklift, good for dock work, loading trucks, and feeding lines in tighter aisles. The service manual is what you pull when the truck is out of warranty and you've got to keep it running over a weekend with no dealer tech in sight. Around my shop that means chasing intermittent electrical faults, fixing leaks, and doing planned component swaps without guessing at settings.

What this manual helps you do

• Trace and diagnose electrical faults using wiring diagrams and connector pinouts.
• Check and adjust hydraulic pressures, valve settings, and mast functions after repairs.
• Follow teardown and reassembly steps for drive units, traction motor, and brake components.
• Troubleshoot fault codes and controller issues on the electric drive and hydraulic systems.
• Verify torque specs, inspection intervals, and service data when you sign off the job card.

Who this is for

This is for a warehouse or plant maintenance tech, dealer technician, independent shop, or rental fleet mechanic looking after an FB20ANT electric counterbalance truck. If you want basic operating instructions or daily checklists, you need the operator's handbook instead, not this manual.

FAQ

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

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

Q: Will it match my serial number and truck variant?

A: The exact serial range isn't listed, so you'll want to confirm your model code is FB20ANT on the nameplate before relying on it.

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

A: Yes, this is the workshop-level service manual, not a parts list or safety/operation booklet.

Bottom line: If your truck is a Mitsubishi FB20ANT and you're doing real repair work, this is the right manual. If your truck is any other model, it isn't.
