Hello. My father just purchased a Volvo EC35C mini excavator and we are having trouble figuring out the operation of the thumb. Anyone with knowledge of the specific controls to get this to operate would be greatly appreciated. I read that some need to be switched over to auxiliary hydraulics but not sure where that is either. My father has been working on heavy equipment all his life. I'm trying to help him out. Thanks for any help.
