Hi to all members, please can anybody help with information on my sumitomo SH75U-1B, i bought this digger secondhand 4/5 yrs ago and used it very little,it developed a control fault once which went as quick as it came however its back and now i can only start the engine and move the dozer blade up and down, other than that it wont track or lift, i linked the safety arm switch out (driver seat arm) but it makes no difference!. I have looked in the uk for information but i don`t think very many sumitomo`s ever came to this country, does any body have a workshop manual or even a wiring diagram, so i can try and find the fault, i understand i will have to pay for this info including shipping. I understand jcb once bought these diggers and put their own badge on.
