Mitsubishi FG20S Forklift Service Manual (99729-10100)

This FG20S is a small LPG counterbalance truck you park in docks and aisles all day, loading trailers and feeding lines. The service manual is what you grab when one dies in the aisle on second shift and you need more than guesses and YouTube. It's the workshop book for the FG20S, built for people who actually turn wrenches and need the right adjustment steps and specs so the truck goes back out and stays out.

What this manual helps you do

• Diagnose LPG engine no-starts, misfires, and power loss on the FG20S, using the right checks and test points
• Trace electrical faults with readable wiring diagrams and connector callouts so you stop chasing the wrong circuit
• Follow step-by-step teardown and reassembly on power train, powershift transmission, steer axle, and brakes
• Adjust hydraulic valves, mast chains, tilt, and carriage so the truck lifts straight and hits spec pressures
• Check and set steering, pedal, and linkage clearances after component swaps or rebuilds

Who this is for

This is aimed at warehouse maintenance techs, dealer techs, independent forklift shops, and rental fleet mechanics working on Mitsubishi FG20S trucks in the CF54-10011-up range. If you're after basic operating instructions or safety info, you want the operator's handbook instead.
