too small but also not too high.
Too little play leads to too much noise developing in the sprockets.
Too much play leads to rattling of the needle bar.
So that the exact movement sequence is retained the two sprockets
are equipped with a center mark. When turning the sprockets the
center marks must lie exactly opposite each other.
Caution Risk of Injury !
