2.5 Function sequence, machine class and operating concept
2.5.1 General function sequence
The DAC Classic control contains the suitable function sequence for almost all VEB
machine classes.
The exact function sequence for a machine class is determined at the control by the
function sequence (basic function sequence and machine selection), the function
parameters and the switchable functions. The control is optimally control-technically
adapted to the respective machine class by correct settings.
On delivery, all function parameters and functions are already set correctly.

3Installation and putting into service
3.1 Unpacking the machine
Strobel machines are delivered either complete or as a machine head with sewing
drive.
Reel stand, rods and other accessories are packed into the packing.
Make sure that all accessories have been unpacked before throwing away any packing
material.
3.2 Installation
C A U T I O N ! Danger of injury!
Entanglement hazard for clothing or hair and Danger of finger
injuries!
Never operate the machine without the belt guards for the
upper part and Sewing drive.
If the machine head is supplied without stand first make the borings into the table top
as shown in the drawing. Mount rods and treadles and electric connections according
to the connecting diagram.
The upper component must be fastened to the provided rubber plate on the table
top.
Mount the lifting and sewing drive operating rods.
Using a compact motor means to assemble the control box and speed controller under
the table. Also the operating rod between speed controller and pedal has to be
connected.
After assembling the single parts of the reel stand mount it to the right hand side of
the tabletop.
Make sure that all screws on the stand are tight and retighten them, if necessary.

10 BA_VEB100-3_A4_230220_en.doc
A T T E N T I O N !
Before putting the machine into service make sure that the
electric connecting data on the sewing drive's name plate, mainly
voltage and frequency, correspond to your electric network.
A T T E N T I O N !
The maintenance instructions according to the operating
instructions must be followed!

11 BA_VEB100-3_A4_230220_en.doc
3.3 Sense of rotation
The correct sense of rotation of the hand wheel is clockwise in line of vision on the
hand wheel.
3.4 Motor drive via Toothed belt
3.4.1 Tensioning the Toothed belt (Fig. 1)
C A U T I O N ! Danger of Injury!
Switch off the machine at the mains when checking the belt
tension. Do not operate the machine without belt guard.
Otherwise DANGER of crushing fingers, of injuries to the body or
of pulling in of part of clothing.
The toothed belt should not be tensioned too much. You should be able to compress
it with light thumb pressure by about 5 mm.
Too little or too tight toothed belt tensioning can impair the positioning of the
machine and therefore impair the function sequence.
Tensioning the toothed belt (Fig. 1):
- Release the upper and the bottom retaining screw (1), (2) at the upper part of
the machine.
- Pull out the sewing drive slightly and tighten the bottom retaining screw (2)
slightly.
- Tension the toothed belt by swivelling the sewing drive.
- Tighten the upper and the bottom retaining screw (1), (2) again.
Fig. 1

12 BA_VEB100-3_A4_230220_en.doc
3.4.2 Positions of the machine
C A U T I O N ! Danger of Injury!
Danger of pulling in parts of clothing and of hair and danger of
crushing fingers and stitching fingers with needles!
When checking positions with switched-on machine keep fingers
and hands away from moving parts.
Machine with or without thread trimmer:
The machine needs a needle position and a reference position.
Reference position t 08 10:
The reference position must be set in such a way, that the point of the needle in
direction of the insertion stitch closes with the right (inner) edge of the needle
slide plate.
Fig. 2

13 BA_VEB100-3_A4_230220_en.doc
Cutting position t 08 13 (Fig. 3):
The needle position must be set in such a way, that when the machine is
stopped, the hook of the thread knife catches the thread loop lying over the
looper securely without touching the looper.
Fig. 3
For the VEB machines we set t 08 12 to the same value as t 08 13/cutting position.
This allows us to disregard the needle position after sewing stop key!
For Strobel, the key "needle position after sewing stop" must be switched on as soon
as t 08 12 has a different value than t 08 13!

14 BA_VEB100-3_A4_230220_en.doc
4Instructions for use
4.1 Needles and threads
The sewing quality can be influenced to a considerable extent by choosing the most
suitable needles and threads for the material to be sewn. It is recommended to use
controlled GROZ-BECKERT needles system 1669 EEO only.
The machine is delivered with needles of size 90/14.
NOTICE: A perfect needle is of great importance for a good sewing result.
Damages of the needlepoint, which often can be made visible under a
magnifier, only may deteriorate the sewing result. Replace the needle in
time!
We recommend twisted polyester filament threads of size 120/2 respectively. Because
of their high strength and ability to slide, combined with a low volume they are to be
preferred over a spun thread.
G u a r a n t e e d r e m a r k !
This machine has been set and sewn off with genuine GROZ-
BECKERT needles.
No guarantee can be granted if the settings are modified for
using other needle types.

15 BA_VEB100-3_A4_230220_en.doc
4.2 Inserting the needle (Fig. 4)
C A U T I O N ! Danger of Injury!
Before replacing the needle, switch off the machine electrically,
and depress the motor switch pedal to make sure that the
machine is truly switched off.
Otherwise there is a danger of injury from crushing and needle
punctures.
The curved needle (1) shape determines its position in the needle lever (2). Attention
should be paid only to ensure that the needle piston is pushed to the stop in the
channel of the needle lever (3) and that the screw (4) of the needle clamping plate (3)
is tightened well.
Fig. 4

16 BA_VEB100-3_A4_230220_en.doc
4.3 Threading and thread course
C A U T I O N ! Danger of Injury!
Switch off machine electrically and confirm that the machine is
really in standstill position by operating the treadle for the
sewing drive control before threading.
Fig. 5 shows the correct threading by using the thread take-up.
Fig. 5
4.4 Thread tension
Depending on thread and fabric quality, nature and thickness the thread tension is set
by tension nut (1) (Fig. 5).
