Chainstitch sewing

The chainstitch is sewn with two threads, one needle and one looper. Normally, the machine trims the fabric edge
while the seam is being sewn. However, a chainstitch seam can be placed at a desired distance from edge of fabric by
putting the upper cutter in B position, disengaging the upper looper and installing coverstitch table B. (See page 10-11)
Turn off the main power switch and unplug the machine.

Machine set up

• Disengage the movable upper cutter. (See page 10)
• Disengage the upper looper. (See page 11)
• Remove cutter cover A and install coverstitch table B (see page 11). The graduations on the coverstitch table indicate
the distance, in cm and inches, from coverstitch middle needle. Use it as a guide when positioning the fabric edge.

Start and end of sewing

When starting to sew after threading the machine, sew 2-3 cm on a scrap fabric and chain off to make a chain. At end of
sewing, pull the fabric lightly to the rear of machine and chain off.

Sewing hints

Pintuck sewing

Sew decorative pintucks on the fabric before cutting
out the garment. Use overlock right needle and select
3-thread overlock, narrow.
Note: The rolled edge stitch can also be used for this technique.
• Disengage the movable upper cutter. (See page 10)
• Mark the fabric with the desired number of pintucks
using a water-soluble fabric marker.
• Fold the fabric with the wrong sides together and sew.
• Press the pintucks in the same direction.

Sew in Circles

(only suitable for heavy and medium weight fabrics)
The extension table has 13 holes in it, used to sew in
circles.
Sew circles with the movable upper cutter engaged (A
position, see page 10) to get a beautiful edge, or disengage
the movable upper cutter (B position, see page 10) and
sew circle embellishments.
• Mark a dot in the center of the area that will be the
circle and place stabilizer under the fabric.
• Pierce the fabric at the mark with the sharp
end of the push pin (A). Place the pin into
the selected hole on the extension table. Push
the pin and its bottom plate (B) together.
• Lower the presser foot and sew. The fabric
will feed in a circle around the push pin.
• When the circle is complete, overlap the seam for a few
centimetres (an inch). Thread the threads into a large
eyed, hand sewing needle and pull them to the wrong
side of the fabric and secure.

Securing the thread chain

Thread the chain into a large eyed, hand sewing needle.
Insert the needle into the end of the seam and pull the
chain into the seam to secure the threads.

Braiding by chaining off

1. Disengage the movable upper cutter. (See page 10)
2. Insert ller cord such as yarn or twill tape through the
hole in the front of the foot.
3. Position the ller cord under the foot and chain off the
desired length.
4. Chained off braids can be used individually or woven
into 3 or 4 ply braids.

Lowering the needle(s)

A
When you stop sewing, the machine always stops with
the needle(s) in the up position. Tap the foot control one
time to lower the needle(s) into the fabric. The needle
down position is useful to hold your fabric in place when
B
making adjustments or when turning the fabric to change
direction when chainstitch sewing.
