Thread Tension; Starting To Sew - Husqvarna Viking Tribute 150C User Manual

THREAD TENSION

Use the recommended top thread tension setting given on
the GraphicDisplay. You might need to adjust the top thread
tension for special threads, fabrics and/or techniques. To set
the tension, turn the numbered tension dial. The higher the
number the tighter the tension.
Normal top thread tension is set to 4-6. When sewing
buttonholes and decorative stitches set thread tension to
around 3. When topstitching with a heavy weight thread
in thick fabric, increase the tension to 7-9. Thread tension
recommendation is always given on the GraphicDisplay for
the selected stitch and fabric.
Make a few tests on a scrap piece of the fabric you are going
to sew and check the tension.
Correct and Incorrect Thread Tension
To understand the correct thread tension, sew a few sample
straight stitches at different settings.
1. Begin with a tension that is too loose, i.e. set at the lowest
number. The bobbin thread will lie straight and the top
thread will be drawn to the underside of the fabric.
2. If you set the tension at the highest number, the bobbin
thread will be visible on the top side of the fabric. The
seam may pucker and the top thread might break.
3. The correct thread tension is set when the threads interlock
in between both fabric layers or, in the case of decorative
stitches, on the underside.

STARTING TO SEW

A straight stitch is selected by default when you turn on the machine. Before starting to sew, select your fabric quality in the
Exclusive SEWING ADVISOR™ feature, and set your machine according to the recommendations on the GraphicDisplay
(page 36).
To start sewing, place top and bobbin thread under the presser foot and to the back. For best results when beginning at the edge
of the fabric, place a finger on the threads to hold them in place as you begin.
Place fabric in position under the presser foot. Lower the presser foot and step on the foot control to begin sewing. Guide the
fabric gently with your hands as the machine is feeding.
See page 27 for reference on how to select another stitch or how to use the Exclusive SEWING ADVISOR™ feature (page 35).
