Mitsubishi mm30sr

[farmerboy]

I like to pass it on loftyofaust. Can you send me the Electrics section and the CPU codes and I will add it to the material I freely pass on. My machine MM55sr now is losing power and stalling. I have biocide in my fuel, have changed all fuel filters and now cleaned and changed hydraulic filters. Works fine for a while (< 2 hours) and then starts to lose rev's and shudder when I ask it to work. Noticed this especially with two simultaneous operations, i.e., lifting a log with bucket and thumb while trying to swing turret. Also track power when in mud. I put new idlers in recently and that improved travel but that was a year before this "shuddering". Your thoughts would be appreciated brothers. All the best from farmerboy.

Where do you get parts for mm55sr ? I live in North Idaho. 50 miles south of Creston BC...

Casey,
Check the seat safety lever switch. Move the arm down and the controls are enabled, move the arm up and the controls are disabled except for the blade and tracks.

Treviftn,
Did you replace potentiometers with OEM or aftermarket. Where did you buy them?

Anna, what is your email? I have a partial electronics manual that helped me with my pe3 code.

My email is K.anahit@gmail.com
If ANYONE has any sort of electro diagrams I'm willing to purchase.

"The hydrolics are working, motor is working, we are able to drive it fine....but the arm doesnt work. The joystick doesnt make the arm move or anything. Specifically the left joystick doesn't wire energy through it, yet when energy is taken straight from the battery, they are able to make it work" The computer doesnt work either. States my uncle who is the owner & is located in Russia. There wasn't a single person out there able to help him, so I hope someone here can. Seems like ya'll know the most!

Hello everyone, I am in need of a service manual and electrical diagrams for a Mitsubishi MM30SR. I am having the same problem as most here, cpu light continues to flash and beep and nothing works. I had read that some had error codes on their machines, I don't see anything that would display a code on this machine.
Can anyone help with manuals for this machine? I am willing to buy them.

Thanks

I have had a Pe2 error and solved it by turning the sensor at the knuckle boom area to a different position and cleaning plugs

I have a MM40sr that is unusable it is displaying SCE error and buzzing. apparantly it is a comunication area between the panel with the display and the control module box. checked wiring. but no problem found there. when the cover is removed from the brain and you can see the circuit board and all its components there is there is a display at the top left hand side that doesnt light up at all and the leds in a row on the right hand side also do nothing. I fear the control unit is cooked and i cannot find anyony that can source parts for this model. I have had pe2 errors and trouble with the earth contacts before but this seems more serious. We rely on this machine and i really need some help please. any ideas or assistance would be greatly apreciated.
