Hello all, I have a 2012 Kobelco SK210-9 that the hydraulic thumb has quit working. Had a automotive mechanic look at it and he says the nibbler open and close relays are not getting ground which keeps the thumb from working. He was not sure how the relay's get their ground so I am asking for some help on what I should do next?
Hey couple questions 1. Does it have a foot pedal aux or rocker switch on the joystick? 2. Are you in nibbler/crusher mode? 3. Are the ball valves open 4. What is your pressure and flow set too on the monitor?
I figured out the problem, I had a bad joystick. I replaced it with one from China and it was bad out of the box. Got new OEM and it’s working fine now. thanks
