1.General notes

The service manual on hand describes the adjustment of the automatic
buttonholer 580 in an appropriate sequence.
ATTENTION !
Various setting positions are interdependent.
Therefore it is absolutely necessary to make the individual
adjustments following the described order.
The operations described in this service manual must only be
executed by qualified staff or correspondingly instructed persons
respectively!
Attention: Danger of breakage !
Before recommissioning of the automatic buttonholer after
disassembly operations first carry out the necessary adjustments
according to these service instructions.
Before all setting operations of parts involved in the stitch
formation:
–	Insert a new needle without any damage.
Caution: Danger of injury !
In case of repair, alteration and maintenance work:
–	Turn the main switch off.	3
	Exception:
	Adjustments carried out with the help of test or adjusting programs.

Adjusting operations and function tests when the machine is running

–Carry out adjusting operations and function tests of the running machine only under observation of all safety measures and with utmost caution.

Adjusting operations in the needle zone

–In order to avoid injuries remove the corresponding parts before carrying out adjusting operations.

Exception:

The parts are absolutely necessary for the adjusting operations.

1.1Necessary program setting

For adjusting the automatic buttonholer the following buttonhole shape has to be set at the control panel:

–Buttonhole without bartack

–Connecting stitch = 0

–No cutting space

–Set the connecting stitch to “wide” (see chapter 9 “Setting the seam width”)

Note!

The set seam width has to be checked not only mechanically but also at the control panel!

2.Adjusting the locking positions

2.1General notes

3

With the help of the locking positions an easy adjustment of the needle motion to the looper and spreader motions is possible.

When the arm shaft is in locking position, the rotary thread take-up disc and the eccentrics for the spreaders, the loopers and the connecting stitch have to be in locking position, too.

The positions have been set by the manufacturer in such a way that standard material can be sewn with the 580.

If you want to use other needle sizes, thread sizes or materials, you may have to set positions slightly differing from the staking-out position.

The locking pins are included in the accessories of the machine and have a diameter of 5 mm.

Caution: Danger of injury!

Turn the main switch off.

Adjust the eccentrics only with the sewing machine switched off.

3

Standard checking

When the arm shaft is locked with locking pin 1, it should be possible to lock the looper eccentric 3 and the spreader eccentric 4, too.

–Lock the arm shaft with locking pin 1.

Important !

In this position the needle bar must be in the upper dead center in front of the left stitch.

–Check with locking pin 2 whether the looper eccentric 5 and the spreader eccentric 6 can be staked out.

Correction

–Lock the arm shaft with locking pin 1.

–Loosen the screws at the looper eccentric 3.

–Turn and lock the eccentric.

–Tighten the screws.

–Loosen the screws at the spreader eccentric 4.

–Turn and lock the eccentric.

–Tighten the screws.

2.3Thread take-up disc

2 1

Caution: Danger of injury!

Turn the main switch off.

Adjust the thread take-up disc only with the machine switched off.

Standard checking

When the arm shaft has been locked with the locking pin 2

in such a way that the looper turret is in its left end position (left stitch), the rotary thread take-up disc 6 should be positioned so that

a drill 4 (2 mm diameter) pushed through the drill-hole of the thread take-up disc rests on the right surface 3.

Correction

					–	Unscrew the tension plate 1.
					–	Loosen the screws at the (timing) gear 5.
					–	Insert the drill 4 through the drill-hole in the thread take-up disc 6.
	6	5	4	3	–	Turn the thread take-up disc until the drill 4 abuts on the surface 3.
					–	Tighten the screws at the (timing) gear 5.

8

2.4Throw eccentric

4	3	2	1	5

Caution: Danger of injury!

Turn the main switch off.

Adjust the throw eccentric only with the machine switched off.

3

Standard checking

When the looper support 5 is in its right end position (right stitch), the locking pin 4 inserted in the eccentric 2 should abut in the indentation 1 at the arm.

–Turn the arm shaft in such a way that the looper support is on the right side (right stitch).

–Put the locking pin 4 in the drill-hole 3 of the eccentric 2.

–Check whether the locking pin 4 abuts in the indentation 1 of the arm.

Correction

–Loosen the screws at the eccentric 2.

–Position the eccentric with the locking pin right on top against the arm.

–Tighten the screws at the eccentric 2.

3.Needle bar positioning

3	2	1	4	2

Caution: Danger of injury!

Exercise utmost caution when making adjustments with the machine running.

Standard checking

When the machine positions automatically after being switched on, the needle bar must be in the top dead centre. The looper turret is in its right end position (right stitch) then.

–Switch the machine on.

The machine positions automatically.

–Check whether the needle bar is in the top dead centre and whether the looper turret is in its right end position (right stitch).
