Installation Notes

Installation and use of this adapter kit should be performed by a qualified technician familiar with threaded insert installation procedures. Before configuring or changing adapters, ensure the manual insert tool is fully disengaged and not under load. Confirm that the AA480N or AA510N handle is on hand before beginning work, as the AA481-420N alone does not constitute a functional system. Follow the tool manufacturer's assembly instructions for correct adapter seating and thread engagement.
