hoistway are intact and there is not evidence of damage or distortion. Check screw column
guides or stabilizing supports to verify that they are intact and functional. If the screw column is
made up of more than one section, special attention should be given to the joints to verify
that there is no indication of shifting or separation of the sections. Utilize procedure previously
