3. With the tabs fully retracted, tabs in position
1 and 3 which overlap the outer ring must be
tightened completely up to the end stroke
with 0.45Nm of torque (at least 7 turns), see
Fig. Mounting Bracket.
4. With the tabs fully retracted, tabs in position
2 and 4 which overlap the outer ring must be
tightened exactly 5 ½ turns, see
Fig. Mount-
ing Bracket.
5. If you are not able to respect the turns some-
thing is incorrect, repeat above instructions,
if issues persist, please contact Ralco.

7. The collimator tabs glide on the flange outer
ring and the collimator rotates towards the X-
ray tube axis. If, however:
• The release force from the position 0°
and the collimator rotation is too low,
the two tabs of the tab 2 and 4 need to
be tightened ½ turn.
• The release force from the position 0° and the collimator rotation is too high, the two
tabs of the tab 2 and 4 need to be loosened ½ turn.
