Mitsubishi FD70NMS Forklift Service Manual (99709-17100)

This FD70NMS is a big diesel counterbalance truck, the kind that lives on docks, yards, and heavy production floors. The people who grab this service manual are the ones who actually have to keep it running when it starts hard, loses power, or drops hydraulic pressure. They're looking for real procedures, specs, and wiring so they can get it fixed today and back in the rotation, not guess at it.

What this manual helps you do

• Diagnose hard-start, smoke, or power loss issues on the diesel engine and fuel system
• Trace, check, and repair electrical faults using wiring diagrams and connector pinouts
• Follow step-by-step teardown and reassembly on the powershift transmission, drive axle, and brakes
• Adjust mast, carriage, and hydraulic settings after hose, cylinder, or valve work
• Troubleshoot hydraulic and steering problems using test ports, pressures, and adjustment procedures

Who this is for

This is the right manual if you're a warehouse or plant maintenance tech, a dealer or independent forklift shop, or a rental fleet mechanic looking after FD70NMS trucks. If you just need operating instructions or daily checks, you want the operator's handbook instead, not this service manual.

FAQ

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

A: You get 16 PDF files split by section, with a real text layer, so they're searchable. Wiring diagrams are in PDF so you can zoom in for detail.

Q: How do I know if it covers my exact truck?

A: It's written for the Mitsubishi FD70NMS series. For borderline serials or odd options, I'd match your model tag and engine type against FD70NMS before buying.

Q: Is this the right document if I'm planning a full rebuild?

A: Yes. This is the workshop-level service manual, meant for real repair work, not a parts book or safety/operations booklet.

Bottom line: if you're wrenching on an FD70NMS and need real repair procedures and specs, this is the right manual. If your truck is a different model prefix, this isn't what you need.
