On a small number of aerial devices, the turntable bolts may not have been tightened properly. As a result, the bolts could loosen and fail. If this happens, the boom could fall.
Safety Risk
A boom that falls could create a risk of injury for the operator and people nearby.
Corrective Actions
Terex will notify owners by mail and provide you with instructions for how to inspect and, if necessary, tighten the turntable bolts. Terex advises you to perform a daily inspection of the bolts and not to use the aerial device if the bolts are loose.
