It had an overhead guard in place in the past when it left the factory (and 'safety for the operator' says it should have a GOOD overhead guard in place still unless you don't lift over the height it is raising to now), and it should still have some wires that used to go up the overhead guard to switches (both sides, as I remember) that told the system that the folding overhead guard was in place to be able to protect the operator from falling objects lifted above his head. when the guard was folded down, it allowed operation in a low overhead, and prevented lifting above a safe level. "Hoist cutout" is the message it gives when any one of those switches did not see it's position as having the overhead guard properly locked in place.
