I believe the red arrow point to the "lock knob" and the blue arrow is the "width dial." Can you loosen (counter-clockwise) the red arrow knob and then turn the blue knob (counter-clockwise, also) so that the flat part is parallel to the bed? I would think that you would need to tighten the knob again so that it only stitches straight. It is possible that there is some dried oil or lint that is blocking it to go where it needs to be to make straight stitch.
