5.8 Adjusting the top feed
On the 173, there is another roller top feed in addition to the bottom
feed. The top feed can be set independently of the bottom feed
and can thus be adjusted individually to the feed behavior of the
relevant sewing material.
When sewing the stitch condensing at the start and end of the
se
am, the roller top feed is automatically adjusted to the shortened
bottom feed.
5.8.1 Adjusting the top feed length
The top feed length can be adjusted by turning the adjusting
wheel (1) continuously between 1 and 4 mm. The adjusting
mark (2) on the left of the wheel indicates the value selected.
