Operating instructions
Feed Dog and Fabric Feed with Height Compensating Tool
Feed Dog and Sewing Corners
The feed dog works accurately when the foot
is level.
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 and the fabric
might jam.
Uneven layers
To solve this problem, place one, two or three
compensating plates as required behind the
needle under the presser foot to level it.
Correct this by placing one or more compen-
sating plates as close as possible to the edge
of 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.
The space between the two rows of feed
dogs is relatively large due to the width of
the stitch plate hole.
To correct the height in front of the foot,
place one or more plates to the right of the
foot close to the needle. Sew until the foot is
level again and remove the plates.
