This Mitsubishi FGC45K is a cushion-tire LPG counterbalance truck, the kind that lives on docks and in plants hauling heavy pallets all day. The service manual is what you grab when the truck is out of warranty, it's throwing a code, or it's due for real work, not just a fluid top-off. Around my shop, this is the book we use when a unit needs to ship tomorrow and we can't afford to guess at adjustments or wiring.
What this manual helps you do
- Diagnose LPG engine issues, trace fuel and ignition problems, and confirm settings after repairs
- Trace, check, and repair electrical and charging circuits using the wiring diagrams and connector callouts
- Follow procedures to pull the powershift transmission, inspect the differential, and reinstall everything correctly
- Rebuild or reseal hydraulic valves and cylinders, then pressure-test and adjust reliefs to spec
- Adjust steering, brakes, mast, and carriage components so the truck tracks straight and lifts clean without chatter
Who this is for
This is aimed at dealer techs, independent forklift shops, rental fleet mechanics, and plant or warehouse maintenance that actually tear into trucks. If you only need operating instructions or daily checks, you want the operator's handbook, not this manual.
FAQ
Q: What format is it in, and can I search it and read the wiring diagrams?
A: It's a multi-file PDF set split by section, with a real text layer, so you can search and zoom in on wiring and hydraulic diagrams.
Q: Will this cover my specific FGC45K truck?
A: It's written for FGC45K trucks in the AF87B-10011-up serial range, so check your data plate against that.
Q: Is this the right document if I'm planning in-house repairs?
A: Yes, this is the workshop service manual with procedures, specs, and diagnostics, not a parts book or safety/operations manual.
Bottom line: If your truck is an FGC45K in that serial range and you're doing real repairs or diagnostics, this is the right manual. If you just need to drive it, it's not.
