Top threader

Attention:

It is important to carry out the threading correctly as by not doing so several sewing problems could result.

Start by raising the needle to its highest point, and also raise the presser foot to release the tension discs.

1. Place the thread and spool holder onto the spool pin. For smaller spools of thread, place spool holder with the small side next to the spool.

2. Draw the thread from the spool through the upper thread guide.

15

3. Guide the thread around the thread guide pulling the thread through the pre-tension spring as illustrated.

4. Thread the tension module by passing the thread between the silver discs.

5. Then, down and around the check spring holder.

6. At the top of this movement, pass the thread from right to the left through the slotted eye of the take-up lever and then downwards again.

7. Pass the thread behind the flat, horizontal thread guide.

16

Attention:

Turn power switch to off ("O") when carrying out any of the below operations!

Raise the needle to its highest position and lower the presser foot.

Lower the needle threader lever slowly and draw the thread through the thread guide as illustrated and then to the right.

The needle threader automatically turns to the threading position and the hook pin passes through the needle eye.

Take the thread in front of the needle.

17

Hold the thread loosely and release the lever slowly. The hook will turn and pass the thread through the needle eye forming a loop.

Pull the thread through the needle eye.

Side thread cutter

Raise the presser foot. Remove the fabric, draw the threads to the left side of the face cover and cut using the thread cutter.

The threads are cut at the proper length to start the next seam.

Lifting the presser foot

Attention:

The needle must always be at the highest position.

The presser foot lifter raises and lowers the presser foot.

When sewing several layers or thick fabrics, the presser foot can be raised a second stage for easy positioning of the work.

Adjusting the presser foot pressure

The presser foot pressure of the machine has been pre-set and requires no particular readjustment according to the type of fabric

(light-or-heavy weight).

However, if you need to adjust the presser foot pressure, turn the presser adjusting screw with a coin.

For sewing very heavy fabric, loosen the pressure by turning the screw counter clockwise, and for thin fabric, tighten by turning it clockwise.

18

Thread tension

Basic thread tension setting: "4".

To increase the tension, adjust to the next number up. To reduce the tension, adjust to the next number down.

Proper setting of tension is important to good sewing.

For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric.

There is no single tension setting appropriate for all the stitch functions and fabrics.

Normal thread tension for straight stitch sewing.

Thread tension is too loose for straight stitch sewing. Adjust to higher number.

Thread tension is too tight for straight stitch sewing. Adjust to lower number.
