I already tried YouTube. I just have a problem with the ground controls. Everything works except it will not lift in either arm. bucket retract works but will not extend. When it happens it raises 6 inches,the alarm goes off and you have to lower it with the cage control to shut the alarm off. I could fix the old one but this has too many safety stuff to bypass anything. I figured someone that works on these could make some money by looking at the symptoms and telling what to do.
