•
Unlock the support arm (1/Fig. 2) and loosen the knob (2/Fig. 2). The support arm
without attached accessories should move through the entire range easily and should
stop in any position.
Readjusting the counterbalance system with accessories
attached
•
If the support arm with accessories attached does not stop in any desired position,
readjust the spring tension for the counterbalance.
•
Remove the cover (3/Fig. 2) from the stand.
•
Release the supplemental brake on the support arm (2/Fig. 2).
•
Move the support arm into the horizontal position.
•
Tighten the screw (4/Fig. 3) using a 17-mm open-ended wrench. Adjust the spring
tension in such a way, that there is a balance when the support arm is in the horizontal
position, i.e. that equal force is required to lift and lower the tube assembly.
