e. Inspect Counterweight Cables.
This step is performed semi-annually.
A cable failure can cause serious patient or operator injury or equipment
damage. This is especially true of the spot-film device vertical-
counterbalancing system in the tower. Worn or damaged cables cannot
be repaired. The cables must be replaced immediately.
Remove the back cover from the tower.
Move the spot film device to its highest possible vertical position.
The vertical carriage is connected to the sides of the counterweight holder by
means of two cables, one on each end.
Visually inspect both cables for the following.
(b) Separation of strands.
Rust and corrosion.
