Dual Feed Balancing Dial
The dual feed balancing dial should be set at “0”.
However, you may need to adjust the dual feed balance
with this dial since the effect of the dual 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 dual feed
balancing dial toward “+”.
(B): If the upper layer puckers, turn the dual feed
balancing dial toward “–”.

Reducing the foot pressure will also improve the feed
balance.
Sewing with the Dual Feed Device
The following stitch patterns can be sewn with the dual
feed device.
Mode 1: 1, 2, 3, 4, 1S, 2S, 3S, 4S
Mode 2: 01, 02, 03, 04
Mode 3: 01, 02, 03, 04
The dual feed device is extremely effective for sewing
with hard to feed material such as vinyl or leather. It also
eliminates layer slippage.
NOTE:
See page 14–15 for how to attach the dual feed foot
and to engage the dual feed device.
Sewing
Raise the presser foot and position the fabric edge next
to a seam guide on the needle plate. Lower the needle at
the point where you wish to start.
Pull the needle and bobbin thread 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.
