the two (2) pointed screws.
NOTICE!

re-assemble the collimator assembly after the
replacement of tubehead.
6. Remove the four (4) nuts that hold the tube-
head to the rotating unit frame and remove
the tubehead.
7. Attach the new tubehead to the rotating unit
frame with the four (4) nuts.
NOTICE!
When tightening the tubehead fastening nuts,
prevent the screws from rotating.
8. Reattach the collimator assembly using the
markings as the indicator for the approximate
location.
NOTICE!
The markings do not guarantee that the unit
alignment remains the same, but they ease the
alignment adjustment work required after the
tubehead replacement.
