Procedure

Undock the patient table and move it from the magnet room.
Remove the upper and lower base covers. See Patient Table Upper and Lower Base Cover Removal.
Raise the table to its maximum height.

Warning

Risk of personal injury

Severe injury can occur if the table is accidentally lowered during maintenance.

When doing maintenance with the table in the Up position, make sure the lock bar is safely engaged.

Lower the table lock safety bar.

Figure 1. Table Lock Safety Bar

Lower the table and verify that all of the table top's weight is resting on the safety bar.
Remove front base cover.

Note: Pressing the actuating button engages the secondary cradle latch cable and causes the pin stop to move down flush with the table top surface, allowing the cradle to slide forward.
Manually slide the cradle forward and prop up the cradle to expose the pin housing and push rod. See Removing Cradle Assembly.
