Accessory box

Fully open work support 15 and take out the accessory box.

The accessory box can only be inserted in its compartment as shown in the illustration. The guide groove of the box must face downwards.

Electrical connection

This machine must only be used on a flat and even surface or on a special sewing table.

Connecting foot control 26:

Insert plug 27 of the control in

machine socket 23, then connect mains plug 28 to the mains socket.

Caution:

Always remember!

When the machine is not in use, always switch it off at main switch 24 and dis connect the plug from the power source. Do not place any objects on the foot control.

Opening and closing looper cover and work support

Push looper cover 12 fully to the right, hold it, and swing it down.

To close the looper cover, push it up until it locks.

To open work support 15, push it in the direction shown by the arrow. To close the work support, push it lightly until it locks.

Selecting stitch types

Stitch types 1 to 8 are illustrated on the machine behind the looper cover. The needle combinations (A, B and C) and the thread tensions used are colourcoded. A needle chart with the corresponding set screws is printed underneath.

Important!

While the looper cover or work sup port is open, power supply to the machine is interrupted.

		Important!
		While the looper cover or work sup
		port is open, the power supply to the

		Threading paths for different stitch
		types on the rear side of the waste
		box.
		On the righthand side the stitch types
		(1 to 8) with the corresponding threa
		ding points A are indicated.
		Each threading path has its own colour.
		Move the slide so that threading point
		A for the required stitch type (1 to 8) is
		coloured orange.
		Now thread all colourcoded threading
		paths, see pages 8 to 1 2.
		Indication B shows you whether the
		overedge looper must be engaged or
		disengaged (see pages 33, 34).
		Please note Only the eight stitch
		types on the rear side of the waste box
		can be set using the slide.
		Other sttch types are shown in the
		stitch selection table (pages 44 to 51).

Threading thread guides 2 and 34 Place thread spools on the spool pins.

Threading must be done carefully. First thread up guides 2 according to colours.

Then lift carrying handle 3 and place the thread in rear guides 34.

Set the thread tensions at N and thread the machine in the following sequence:

1.right looper (red)

2.left looper (yellow)

3.right needle (green)

4.left needle (blue)

Fold carrying handle 3 down again.

Needle combinations

In the table behind looper cover 12 the needle combinations for stitch types 1 to 8 are indicated.

Remove any needles not in use by loo

sening their set screws A, B or C (for needle change see page- 40).

Threading the right looper

Thread the right looper in sequence 1 to B and pull about four inches of thread through the looper eye. The thread path is marked in green in the threading diagram on the rear side of the waste box.

Important:

In order to achieve perfect sewing results, the thread must be pulled between the tension discs during threading.

Note:

Changing a spool with the machine threaded

Cut the threads off close to the thread spool. Place new thread spools on spool holders 22. Tie the ends of the old thread and new thread together. Pull the needle threads out of the needles. Now pull the threads through until the knots are about six inches past the last thread guide before the needles. Cut the knots off and thread up the respective needles. The looper threads can be pulled through beyond the looper eyes. Pull about four inches of thread through the looper eye.

Seam depth graduations:

Application example:

If the seam allowance of a cut part is 20 mm, the edge of the butting must be guided along the 20 mm graduation on knife guard 10.

Press the waste box downwards against the front cover until it snaps in place.

Points to remember during sewing!

Sew the first stitches sIowy. If the machine has been rethreaded, place the fabric under sewing foot 8 and push it up to the needle before starting to sew.

Since the fabric is fed automatically, do not pull or push the fabric. Use your hands for guiding only

Thread cutter

In order to use thread cutter 42 it is necessary to sew beyond the end of the seam.

Draw the resulting thread chain through the thread cutter from the rear (see bottom illustration).

Securing the seam

Knot the thread chain. For knit fabrics, a crochet needle can be used to pull the thread chain into the seam.

Or:

Sew about two inches beyond the end of the seam. Turn the workpiece around and sew a few stitches over the seam just sewn without cutting the thread chain.
