Cutting Width Adjustment

Turn off the main power switch and unplug the machine.
When the cutting width is too narrow or too wide for the set
seam, adjust it by moving the staionary cutter.
Turn the cutting width adjustment dial to move the stationary
cutter to the right or left.
Perfect Cutting width (A) – The edge of the fabric should align
with the seam.
Too narrow cutting width (B) – there is a gap between the edge
of the fabric and the seam. Increase the cutting width by turn-
ing the cutting width adjustment dial away from you.
Too wide cutting width (C) – the fabric gets rolled or folded
into the seam. Decrease the cutting width by turning the cut-
ting width adjustment dial towards you.
Sew and check the cutting width.
The standard position for the stationary cutter is when the
right edge of the cutter (D) is aligned wih the guide line on the
stitch plate (E).

Stitch Length Adjustment

The stitch length dial (A) should be set to 3 (approximately 3
mm) for most sewing conditions. The dial clicks when you turn
the dial to 3. The stitch length can be adjusted while sewing.
The stitch length can be adjusted from 1 to 5 mm.
Adjust the stitch length to 4 mm when sewing on heavyweight
fabrics.
Adjust the stitch length to 2.5 mm when sewing on lightweight
fabrics.
Set the stitch length to "R" for rolled and narrow hem (ap-
proximately 1.5mm).

Stitch Finger Lever Setting

The stitch finger (A) is used to stabilize the fabric edge when
forming stitches. The stitch finger lever should be set to "N"
for all standard overlock sewing (B). To sew rolled edge you
need to retract the stitch finger by setting the stitch finger lever
to "R" (C).
When moving the stitch finger lever, be sure to push the lever
as far as it will go in each direction.
