14. Needle guard adjustments
The needle guard is positioned on the feed dog support and is moving in the same time with the
feed dog, for that reason the needle guard position have to be checked every time the stitch
length is changed. The needle guard have to touch the needle just a little bit, only for support,
don’t have to push the needle and the have to touch the needle right under the needle hole.
The screw A (image 29.1) is used to adjust the height position and the screw B (image 29.3)
to adjust the back-forward position.
