I feel like I am missing something. Undid the four 9/16 bolts, and the motor won't pull away. Feels like it is stuck to the bottom of the front of the stand. Is there a bolt Iim missing?[attachment=1:3d8x542m]ImageUploadedByTapatalk1390066467.433011.jpg[/attachment:3d8x542m][attachment=0:3d8x542m]ImageUploadedByTapatalk1390066477.766583.jpg[/attachment:3d8x542m]
