Sewing with the Upper Feed Device
Patterns number D1, D2, D3, D4, D96, D97, D98, D99,
D100, D1S, D2S, D3S, D4S, D97S and D98S can be
sewn with the upper feed device.
The upper feed device is extremely effective for sewing
with hard to feed material such as vinyl or leather. It also
eliminates layer slippage.
Sewing
Raise the presser foot and position the fabric next to a
seam guide on the needle plate. Lower the needle at the
point where you wish to start.
Pull the needle toward the rear. Lower the presser foot.
Start sewing at medium speed. Gently guide the fabric
along the seam guide letting the fabric feed naturally.
When seaming plaid fabrics, match the plaids of the
upper and lower layers and pin them together.
Upper Feed balancing Dial
The upper feed balancing dial should be set at "0".
However, you may need to adjust the upper feed balance
with this dial since the effect of the upper feed varies
depending on the type of fabric.
Test sew on scrap piece of the fabric you intended to sew
to check the feed balance.
(A): If the lower layer puckers, turn the upper feed

balance.
