Thanks Mathew,
A JLG tech finally came out to site to inspect and tested the unit. In his opinion it is safe to use despite the uncontrolled reverse action. He had previously adjusted some setting via his programming unit but that's the best he can do. So it's still tagged out of service awaiting replacement from the hire company. Hopefully the next JLG unit doesn't do the same.
Cheers, Gibbo.
