For rewinding, I turn the knob below the shutter release as far clockwise (down) as it will go. Once the film is set in the reel then for loading, I return the knob to the counter clockwise and turn the film advance knob to make sure there's tension. I've noticed that sometimes it will take a little bit to catch.
And sometimes it will not catch , that is if the shutter button happens to get rotated a hair counter clockwise .
And that`s exactly what I `ve been trying to explain here.
