Feed-dog and fabric feed
Feed-dog and stitch length
With each stitch the feed-dog moves forward by one step.
The length of this step is determined by the stitch length
selected. With an extremely short stitch length, the steps
Important
Let the fabric feed evenly!
Height Compensating Tool
The feed-dog can work
normally when the foot is
level.
Feed-dog and sewing corners
The gap between the two
rows of teeth is relatively
large due to the width of the
stitch plate hole.
Pulling or pushing will
result in gaps.
If the foot is at an angle,
e.g. when sewing over
thick to thin or vice-versa,
the feed-dog cannot grip
and feed the fabric.
When sewing corners
only a small section of
the fabric is actually on
the feed-dog so that it
cannot grip the fabric
well.

are short. The fabric moves under the foot quite slowly,
even at full sewing speed. Buttonholes, satin stitch and
some decorative stitches are sewn with a very short stitch
length.
Holding back will result in
thread build-up.
To solve this problem,
place one, two or three
compensating plates as
required behind the needle
under the presser foot.
Correct this by placing one
or more compensating
plates as close as possible
to the edge of the fabric.
To correct the height in
front of the foot, place
one or more plates to the
right of the foot next to
the needle. Sew until the
foot is level again and
remove the plates.
