As I recall there are two ways to set the drums. All the doors I have installed say to use vice grips or something to clamp the shaft in place. Then hand wind one drum and tighten the screws. Then hand tighten the other drum. After that wind the spring and then release the shaft.
The alternative (which I haven't used) is to not clamp the shaft in place but use a single wind of the shaft to keep tension on the first drum. I like clamping the shaft.
