I have had the same problem. Have either of you fixed your problem yet? I have a copy of the Diagnostic Manual for the Electronic system for Mitsubishi MM30SR , MM40SR , MM55SR , MM55SR-2 These were translated from the original Japanese. Also have parts manual for MM30SR. Does anyone know how I could reach these guys? Thanks td6man
Regarding the electrical lockup of the swing and digging controls: I have found that by pressing the reset button while the machine is running will erase the error code and present instead all flashing eights on the readout. Once you see the all flashing eights then the machine will operate yet without the aid of the rotate, elevation and boom angle readouts. The reset button is located next to the ISO/ANSI switch and fuse panel under the operator seat.hello i have 96 mm40 have four years for lifting logs digging around my yard it
