3. Connect three elements 1, 2, 3 using clamps 4, moving them along the guide (fig. 3).
5. Tighten a belt using a belt tensioner 6 (fig. 5) in such a way that the distance between teeth is equal to not less than
0.5cm when the belt is pressed down.
ATTENTION!
During start-up and slowdown stages in case of big doors the belt can transiently slack in relation to a tire
section. However, this phenomenon does not have any negative consequences in a technical sense, and does not have
any adverse effect on operation of the drive and its service life.
4. Fix clamps 4 by means of a clamp lock 5 (fig. 4).
