2.3.2.2 Rotational Locking Pin
Refer to Figure 2-16. To prevent uncommanded motion of the rotating assembly, the rotational
locking pin must be engaged anytime the rotating assembly is serviced.
Figure 2-16: Rotational Lock Assembly
The rotational lock is located on the rear side of the gantry, near its top. It is positioned directly
across from the teeth in the rotational assembly. Refer to Figure 2-17. To operate the lock:
• Turn the handle clockwise until the teeth on the lock fully engage the teeth on the rotating
assembly. You can rock the rotating assembly slightly, if its necessary to align the teeth.
Hand tighten until snug. Do not over tighten. Visually verify that the teeth are engaged.
• Turn the handle counter-clockwise until the teeth on the lock and the rotating assembly are
fully disengaged and the teeth clear each other sufficiently.
