A blinking diagnostic code with the truck dead in the aisle is where the Mitsubishi FB16PNT, FB18PNT, FB20PNT operator manual PDF earns its keep: 202 factory pages, part number 99750-7P110, for electric forklifts in MC (mechanical control) and FC (fingertip control) versions. Maintenance fills about a fifth of the book, scheduled by the hour meter from the 10-hour pre-start check to the 2000-hour annual service, with the parts to change periodically. A diagnostic code list backs up troubleshooting for sudden shutdowns, a dark monitoring display, mast faults and manual magnet brake release, and the tipover chapter explains load center and capacity plates. Set brake pedal free play at 5 to 7 mm, and bring front wheel nuts to 216 to 264 N·m after a tire change. Guess at a code and you buy the wrong contactor. Bookmarks and a searchable text layer take you straight to your answer, and the truck is lifting pallets again before the next shift.

Mitsubishi FB16PNT, FB18PNT, FB20PNT Common Problems This Manual Covers
Mitsubishi FB16PNT battery plug or main circuit fuse problem, forklift truck shuts down suddenly mid-shift
Check that the battery plug and connector are fully seated and have not backed out, following page 146. Inspect the main circuit fuses next; the line fuse for the traction and pump motors is rated 500A on page 147. Replace a blown fuse only with one of the same rating, and find out why it blew first.
Manual Section: Forklift Truck Shuts Down Suddenly p. 146Central vehicle monitoring system on the meter panel does not come on at startup
Check that the battery plug and connector are fully engaged and not loose, following page 147. Verify battery condition and state of charge, then inspect the fuses for a blown element. Recharge a run-down battery before going any further. If the display still stays dark, have a Mitsubishi technician check the circuit.
Manual Section: Central Vehicle Monitoring System Does Not Come On p. 147Blown fuse or burned-out bulb suspected when the forklift truck lights won't glow
Inspect the fuses for the lighting circuit following page 147, and replace a blown fuse only with one of the same rating. If the fuses check good, inspect each bulb and replace any that has burned out. Switch the lights on again and confirm every lamp glows before the truck goes back on shift.
Manual Section: Lights Won't Glow p. 147Diagnostic code blinks or glows on the display and the forklift truck stops moving
Check the direction lever, accelerator pedal, seat belt and control levers, because those are the inputs the manual lists for this condition. Set each one to its proper position, then read the code against the diagnostic code list on page 155. If the code stays lit, tag the truck out and call for service.
Manual Section: Diagnostic Code Blinks or Glows and Forklift Truck Stops MovingBattery disconnect switch issue, mast and attachments malfunction or fail to operate from the control levers
Check the battery disconnect switch first. The manual lists it as the starting point for mast and attachment malfunctions. Verify the switch is fully engaged, then run the mast through lift and tilt with no load on the forks. If the mast still misbehaves, look for a diagnostic code on the display and match it on page 155.
Manual Section: Mast and Attachments MalfunctionLift cylinders drift down and mast tilts forward on its own with a load raised
Measure lift cylinder drift following the check on page 188. Lowering must not exceed 50 mm (1.97 in) in 15 minutes. Check tilt cylinder forward drift the same way against 12 mm (0.47 in) in 15 minutes on page 189. If either reading is over the limit, park the truck and report it to your service technician.
