Procedure

Undock the patient table and remove it from the magnet room.
Make sure the table lock safety bar is lowered and the weight of the table is resting on it.

Using a small screwdriver, remove the e-clip shown above. There are four parts to remove from the pin.
1. Maneuver the plastic link lever off both the guide and the pin.
2. Slide the reel off the pin, attached to a spring (it will tend to pull away after it is removed).
3. Slide the bushing off the pin.
Before removing the lever, locate and remove the e-clip that holds the link bar to the pedal at the rear of the table with a small screwdriver.
