3. Never operate this sewing machine if it has a damaged cord or plug, if it is not working properly, if it
has been dropped or damaged, or dropped into water.
Return the appliance to the nearest authorized dealer or service center for examination, repair,

electrical or mechanical adjustment.

4. Never operate the appliance with any air opening blocked. Keep ventilation openings of this sewing
machine and foot controller free from accumulation of lint, dust and loose cloth.

Raising and Lowering the Presser Foot

The presser foot lifter raises and lowers the presser
foot.

You can raise it about 0.6 cm (1/4˝) higher than the
normal up position for easy removal of the presser
foot, or to help you to place heavy fabric under the
foot.

1. Lowered position

2. Raised position (Normal)

3. Highest position

Balancing Thread Tension

Auto tension

This machine features the Auto setting in the tension
control, which covers wide range of sewing condition.
Set the tension control dial at “ Auto ” for general
sewing, unless specifically indicated in this manual.

Manual tension adjustment

Manual tension adjustment may be needed depend­ing on the sewing materials, layers of fabric and other
sewing conditions.

1. Thread tension dial

2. Setting mark

3. Needle thread

4. Bobbin thread

5. Right side of the fabric

6. Wrong side of the fabric

[1]Correct tension:

The ideal straight stitch has threads locked between
two layers of fabric.
For an ideal zigzag stitch, the bobbin thread does not
show on the right side of the fabric, and the needle
thread shows slightly on the wrong side of the fabric.

[2]Needle thread tension is too tight:

The bobbin thread will appear on the right side of the
fabric.

Loosen the needle thread tension by moving the dial
to a lower number.

[3]Needle thread tension is too loose:

The needle thread will appear on the wrong side of
the fabric.
Tighten the needle thread tension by moving the dial
to a higher number.

1. Needle clamp screw

2. Stopper pin

3. Flat side

To check the needle:

Place the flat side of the needle onto something flat
(needle plate, glass etc).
The clearance between the needle and the flat surface
should be consistent. Never use a bent or blunt needle.
CAUTION: A damaged needle can cause permanent

snags or runs in knits, fine silks and silk-like
fabrics.

Selecting Threads and Needles

* For general sewing, use needle size #11/75 or #14/90.
* A fine thread and needle should be used for sewing lightweight fabrics, so the fabric will no be marred. Heavy

fabrics

require a needle large enough to pierce the fabricwithout fraying the needle thread.

* Always test the thread and needle size on a small piece of fabric, which will be used for actual sewing.
* In general, use same thread for needle and bobbin.
* When sewing stretch, very fine fabrics and synthetics, use a Blue tipped needle. The blue tipped needle

effectively prevents skipped stitches.
