I just installed a thumb I'm my mini exc and am having trouble with the hydraulics Is there any programming or bleeding that needs to be done?
I'd imagine you have the newer touch screen? I've used the bigger Volvo where you have to select tool type.
You have the valve just under the door turned to the thumb setting and not set for hammer? Might be a silly question but i sometimes forget when changing from a hammer and the thumb wont work.
