Testing and readjusting the counterbalance
5
•
Loosen the rotating knob (2/Fig.20) and unlock the C-arm (1/Fig.20).
It should be possible to move the C-arm without any attached accessories easily across
the whole range and the arm should come to a stop in any desired position.
Readjusting the counterbalance with accessories attached
5
If the C-arm with accessories attached does not come to a stop in any desired position,
readjust the spring tension for the counterbalance.
•
Remove the cover (3/Fig.20) at the stand.
•
Release the supplemental brake at the C-arm (2/Fig.20) completely.
•
Move the C-arm into a vertical position.
•
Tighten the screw using a 17 mm Allen key (4/Fig.21).
Adjust the spring tension in such a way, that there is a balance when the C-arm is in a
vertical position, i.e. that equal force is required to lift and lower the tube assembly.
