I need too service manual mm40sr or mm55sr . Someone help? nhoduongchau@gmail.com
My new friends. Here is a link to CFTERPILLAR 305 . I'm looking for the user manual and service manual for MITSUBISHI MM30CR-2. At whom is , share with me.
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
My MM30SR flashes E-21 on the screen. I have to push the red circuit reset button by the fuses to make the boom work. Does any one have any ideas of the problem as I have no manuel.
Don't know on the MM30SR but on the MM55SR-2, E-21 is a cut/short wire on the boom potentiometer, which sounds like where your problem is originating given your "fix".
The Entire system is hydro. not electronic controls. any other ideas?
On the mm55 the red button next to the fuses is the Anti-Interference Cancellation Switch. Do you have limiters on the boom?
