4.12 Finetuning the upper transport (Fig. 14)
Fig. 14
The feed dog is adjusted to its height by a threaded bar (1) with a lever (2) and an
eccentric bushing (3).
The transport movement remains, through turning of the threaded bar (1) the feed
dog can be adjusted to its height in order to eliminate warping of the sewing material.
It is important that this adjustment goes easily. Since the aluminium plate (4) is
secured by only the bolt (5) with screw (6) and can be twisted somewhat, ensure that
none of the movable parts get jogged or caught.
Setting procedure:
1. Set stitch length at head to 8 mm.
2. Insert large eccentric bushing (7) with eccentric bore hole to the rear in the
head. (Fig. 14)
3. Mount lever mechanism with eccentric brass bushing with bore holes towards
the front.
4. Set the feed dog to such a height that the transport supports jam when the
needle's point is on the right edge of the needle glide washer.
5. Set stitch length at head to 6.5 mm.
This setting is a bit difficult, because the feed dog can be shifted in all directions
because of the large bore hole.
