Chain/Cover Stitch Tension Dials
The tension system of the chain and cover stitches are completely separate from the system being used on the
overlock stitches. Unlike the thread delivery system of the overlock stitches, the tensions of the chain / cover
stitch needles and chain looper are adjusted by dials located on the outer sides of your Evolution.
Needle Tension Dial
The needle tension dial is located on the top left side of the machine. One tension dial controls all 3 of the
chain/cover stitch needle selections. Normally set at "5", the dial can be turned from 0 - 9 to increase or decrease
the tension on the chain/cover stitch needle threads.
Increase the tension by turning the dial to a larger number.
Decrease the tension by turning the dial to a smaller number.
Align the number with the indicator mark on the front of the machine near the dial.
Chain Looper Tension Dial
The chain looper tension dial is divided into 2 sections - Chain Stitch and Cover Stitch. The dial is located on the
top right side of the machine. Align the selected tension setting with the indicator mark on the front right of the
machine.
The Chain Stitch section of the looper tension dial has a tighter looper tension for sewing chain stitch.
Select the row of stripes on the dial for chain stitching. The wider the stripe the tighter the chain looper
tension.
The Cover Stitch section of the looper tension dial has a looser tension for sewing wide, narrow or triple
cover stitches. Select the solid line on the dial for cover stitch tension settings. The closer to the wide hor-
izontal mark indicates looser tension for cover stitching.
