Should the support arm not come to rest in every position with affixed accessories, then
readjust the spring tension for the weight counterbalance.
• Remove the cover on the stand (3/Fig. 1).
• Release completely the additional brake on the support arm (2/Fig. 1).
• Move the support arm into the horizontal position.
• Tighten the screw (4/Fig. 2) with a 17 mm fork wrench.
Adjust the spring tension so that there is equilibrium in the horizontal support arm
