Battery, drive and pump motors, AC controller, steering, both brakes, hydraulics and mast: the Hyster J30UTT service manual PDF (OEM ID 4282423) works through each in 61 pages for the J30UTT, J35UTT and J40UTT counterbalanced 3-wheel battery forklift trucks. Wiring diagrams trace the 48V circuits through the AC motor controller and instruments, and the fault code listing tells you what the controller is reporting. Hydraulic schematics show the route from the gear pump through the multi-way valve, orbitrol and speed limit valve, with fault diagnosis for pump, valve, steering and brakes. Set the safety valve at 14.5 MPa on the J30UTT and 17.5 MPa on the J35UTT and J40UTT. Your job may be adjusting fork carriage height, setting the brake switch, or disassembling and reinstalling the mast. Bookmarks and a searchable text layer come with it. Save the file to a tablet and it goes wherever your truck is parked.
