I'm wondering if someone could tell me what "UP" then "EE" warning code is, the buzzer sounds on and off. sometimes continuously whether using the controls or just idling. thx :Banghead

    Sounds like a malfunction in the "4 link" system. There is an override under the seat, its a toggle switch located between your knees if your sitting in it. When mine failed it was a bad connection/wire somewhere around the potentiometers on the boom.
