Mitsubishi FG20K FC Forklift Service Manual (99719-53120)

This FG20K FC is a small LPG cushion-tire counterbalance truck, the kind that lives on docks and in tight warehouse aisles pulling pallets off trailers all day. Around my shop, this service manual comes out when a truck is down in the aisle and you need hard data, not guesses, to get it back before the next wave hits. It's the workshop book: you use it when you're chasing a drive issue, a hydraulic problem, or an engine fault and you need specs and step-by-step procedures.

What this manual helps you do

• Trace LPG engine problems, check systems, and follow teardown and reassembly steps for the FG20K FC powertrain
• Diagnose and repair the automatic transmission, differential, and drive axle to stop slipping, noise, or no-drive complaints
• Check, adjust, and rebuild steering, service brakes, and parking brake so the truck tracks straight and stops right
• Pressure-test and troubleshoot the hydraulic system, then rebuild or replace pumps, valves, tilt and lift components, mast, and carriage parts
• Read and follow wiring diagrams to diagnose charging, starting, and electrical faults when the truck won't crank or keeps blowing fuses

Who this is for

This is for a warehouse or plant maintenance tech, dealer tech, independent forklift shop, or rental fleet mechanic keeping FG20K FC trucks alive between shifts. If you just need operating instructions or daily checks, you want the operator's handbook instead, not this manual.

FAQ

Q: What format is it in, and can I search it?

A: It's a multi-file PDF set, split by section. It's a scanned image manual, so you can zoom and print, but you can't text-search it.

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

A: It's written for FG20K FC trucks in the EF17B-15001 and up range. If your plate shows that prefix and a higher number, you're in the right place.

Q: Is this the right document for general maintenance and repairs?

A: Yes, this is the full service manual for shop-level diagnostics and repairs, not a parts book and not an operator's manual.

Bottom line: If you're wrenching on an FG20K FC with an EF17B-15001-up serial, this is the right service manual. If your model or serial don't match, skip it.
