The Dock Contains Ferrous Materials and may be pulled into the magnet bore if securing hardware is removed.
Only loosen the hardware sufficiently to perform adjustments in this procedure. ensure THE DOCK remains secured TO PREVENT IT FROM BEING PULLED INTO THE MAGNET BORE.
At the rear of the dock, loosen the top and bottom dock bracket nuts (2 on each side).
Figure 1. Dock Bracket Nuts Get the table removed earlier (first table) and do a check of table alignment/levelness with the bridge to make sure of smooth travel. Adjust the height as needed according to Leveling Patient Table . Adjust left/right according to Dock Centering and Dock Hook Tension Adjustment Undock the first table and get the second table.
