Checking and readjusting the counterweight

•
Unlock the support arm (1/Fig. 7) and release the turning knob (2/Fig. 7).
Without any accessories attached, the support arm should be easy to move across the
entire movement range and stop in any position.

Readjusting the counterweight with accessories attached

If the support arm does not stop in any position with accessories attached, readjust the
spring tension for the counterweight.
•
Take the cover (3/Fig. 7) off the stand.
•
Completely release the additional brake on the support arm (2/Fig. 7).
•
Move the support arm into the horizontal position.
•
Tighten the screw by means of a 17mm fork wrench (4/Fig. 8).
Adjust the spring tension so that the support arm is balanced in the horizontal position,
i.e. the forces needed for lifting and lowering the tube unit are equal.
