1. General

These Service Instructions 558 describe in a practical order the

settings for the sewing machine.

ATTENTION

The tasks described in the service instructions may only be conducted

by specialists or suitably trained personnel !

Since various setting positions are interdependent it is essential that

the settings be made keeping to the order described.

ATTENTION Danger of Breakage

After disassembly and before recommissioning of the sewing machine

the testing described in the Chapters 11,12,14,16,18,24 and 28 is to

be conducted !

With material in place and the needle making a stitch the machine may

not be advanced using the hand crank.

Caution Risk of Injury

Prior to repair, conversion and maintenance work pull the mains plug.

Adjustment work and function testing with the machine running may

only be conducted with the greatest caution while observing all safety

measures.

2. Handwheel

The freeing of the drive pulley 6 when turning off the machine is done

by disengaging the handwheel 1.

The timing for the disengagement is determined by the switch surface

3.

The turn-off link 5 with the roller 4 lies onto the handwheel.

When reaching the switch surface it releases and the disengaging

roller 2 falls in to disengage the handwheel.

Caution Risk of Injury !

Pull the mains plug before setting.

In order that the full sewing speed not become effective at the brake

lever 7, the handwheel, however, reaches the end position (needle

high position) with certainty, it must be set as follows:

With the catch groove 8 of the brake cam 9 standing vertical at the top

the roller 4 should lie opposite the switch surface.

12. Cloth Clamp Pressure

Through the spring-mounted clamp frame 2 found under the material

support plate the pressure of the upper cloth clamps is automatically

adjusted to the material thickness.

The pressure of its compensation springs 4 is set at the factory.

Normally it should not be altered.

The clearance between the upper frame piece 3 and the lower frame

piece 4 should be 14.2 mm up to +0.5 mm.

The setting is only possible with clamp frame removed.

The cloth clamp pressure must be set so that even the thinnest

material to be sewn is still securely clamped.

Caution Risk of Injury !

sewing the clamp operating lever 1 must be set a little beyond its

strongest pressure point.

Exceeding the pressure point too much can result in:

–

Unwanted weakening of the cloth clamp pressure.

–

The cloth clamps are no longer opened automatically by the clamp

closing lever.

Setting and checking is to be conducted with the clamping plates in

place.

Caution Risk of Injury !

Pull the mains plug before setting.

14. Pressure of the Clamp Closing Lever

When starting the sewing procedure the upper cloth clamps are

automatically closed by the movement of the clamp closing lever 3.

The clamp operating lever 2 must thereby be moved with certainty in

front of the stop screw 4.

For this in the lowest position of the closer 1 there must be a clearance

of 0.1 mm between it and the angle lever 5.

Caution Risk of Injury !

Pull the mains plug before setting.

–

Turn the hand crank until the closer 1 reaches its lowest position.

–

Loosen screws 6.

–

Set a clearance of 0.1 mm between closer 1 and angle lever 5.

–

Tighten screws 6 again.

ATTENTION !

The flawless functioning of the clamp closing lever is dependent on the

precise settings of chapters 11 to 15.

If one of these settings is changed, then all settings for chapters 11 to

15 (in this order) must be made.

15. Position of the Clamp Closing Lever

On the clamp closing lever 1 are to be found the closer 5 for automatic

closing and the tappet 6 for automatic opening of the clamping plates.

Depending on the execution of the Sewing machine for

a) cutting after sewing

b) vor and cutting after sewing

different settings of the clamp closing lever become necessary.

Caution Risk of Injury !

Pull the mains plug before setting.

a) Cutting after sewing

–

With clamping plates closed turn the sewing machine out of the

end position with the hand crank until the hook block has turned

180°.

In this position the underthread tension 4 points to the rear (shown

in the picture to the front).

–

Turn farther until the cutter bar lowers and the cutting block lies

above the knife.

–

Loosen screw 3.

–

Set the tappet 6 tight on the angle lever 2 by pulling up on the

clamp closing lever 1.

–

Tighten screw 3 again.

ATTENTION !

The flawless functioning of the clamp closing lever is dependent on the

precise settings of chapters 11 to 15.

If one of these settings is changed, then all settings for chapters 11 to

15 (in this order) must be made.

b) Cutting before and after sewing

By sewing machines laid out for cutting before and after sewing two

cams on the main control disc control the movement of the clamp

closing lever.

The first cam in the direction of turn conducts the closing movement

for cutting before sewing and the second cam for cutting after sewing.

Two stops, between which the clamp closing lever can be adjusted,

limit the positions.

Caution Risk of Injury !

Pull the mains plug before setting.

–

With clamping plates closed turn the sewing machine out of the

end position with the hand crank until the hook block has turned

360°.

In this position the underthread tension 5 points to the front.

–

Move stop 6 in direction N (see sticker) until touching.

–

Turn the sewing machine out of the end position with the hand

crank until the hook block has turned 360°.

In this position the underthread tension 5 points to the front again.

–

Turn a bit farther until the closing movement of the clamp closing

lever downward starts (for cutting before sewing).

–

Turn farther until the clamp closing lever moves upward again.

With the upwards movement the tip of the tappets 4 must move

past as close as possible to the tip of the angle lever 3. The two

tips may not, however, thereby touch.

–

Loosen screw 2.

–

Set clamp closing lever 1 appropriately.

–

Tighten screw 2 again.

–

Bring stop 7 to touching in direction V (see sticker).

ATTENTION !

The flawless functioning of the clamp closing lever is dependent on the

precise settings of chapters 11 to 15.

If one of these settings is changed, then all settings for chapters 11 to

15 (in this order) must be made.
