Push edge guide “N” through hole “A” and secure it in
position with screw “B”. The guide can be adjusted to
the desired stitching margin for various applications.
With attached edge guide, it is easy to sew parallel
lines of stitches or to stitch parallel to the edge. The
guide either following an edge (Fig. Q) or, when
making parallel lines of stitches, run along the
preceding line of stitches. The seam thus looks more
neat and accurate.

Dual Feed Transporter/ DFT system:
We offer the ideal solution for sewing
difficult material:Dual Feed Transporter.
This system feeds the material from the
top and bottom simultaneously as is done
in industrial sewing machines. The fabric
is fed precisely. When sewing light or
heavy material such as silk and rayon
fabrics, the dual feed prevents seam
puckering.
The even feeding action also ensures
perfect matching of checked and striped
fabrics.
Engaging the Dual Feed Transporter:
Important: For all sewing jobs with the
top feed, only use sewing feet which is cut
out at the back.
Raise the presser foot. Then push the top
feed downwards untill it snaps into its
place.
Disengaging Dual Feed Transporter:
Hold the dual feed with two fingers at the
marked places. Push the top feed down a
little and out to the rear, and let it move
slowly upwards.

Thread tension:
Upper needle thread tension (Figure 1):
- For the best stitch
appearance and durability,
make sure the needle thread
tension is correctly adjusted.
For general sewing, the
threads evenly meet
between the two layers of
fabric
- The normal setting for utility
stitches is in the range 4-5.
- To increase the tension, turn
the dial to the next number
up.
- To reduce the tension, turn
the dial to the next number
down.
Figures:
A.Normal thread tension for
straight stitch sewing.
B. Thread tension is too loose
for straight stitch sewing.
Turn dial to higher number.
C. Thread tension is too tight
for straight stitch sewing. Turn dial to lower number.
D. Normal thread tension for zigzag and decorative sewing.
Note:
To obtain better zigzag and decorative stitches, the upper tension should be
slightly weaker than in the case of straight sewing, thus the upper thread appears
slightly on the bottom side of fabric.
Lower needle thread tension (Figure 2):
To check the bobbin thread tension , remove the bobbin case and bobbin and hold
it by suspending it by the .Jerk it once or twice. If the tension is correct, the bobbin
thread will unwind by about 2.5 to 5 cm downward.
- If the tension is too tight, turn the small screw on the bobbin case slightly counter-
clockwise.
- If the tension is too loose, turn the small screw on the bobbin case slightly
clockwise.
Note:
The bobbin thread tension does not normally have to be adjusted.
