Operation
4.8 Thread tension
Together with the hook thread tension, the needle thread tension influences the final seam pattern. With thin sewing material, excessive thread
tension can lead to undesired gathering and thread breakage.
Proper setting
If the tension of needle thread and hook thread is identical, the thread
interlacing lies in the middle of the sewing material.
Set the needle thread tension so that the desired seam pattern is achieved
with the lowest possible tension.

(6) - Needle thread loop
The needle thread regulator (2) controls the quantity of thread required for
the stitch formation.
The needle thread regulator has to be precisely adjusted for an optimum
sewing result.
The setting of the needle thread regulator depends on the following factors:
• Stitch length
• Thickness of the material
• Characteristics of the yarn utilized
With correct setting the needle-thread loop (6) should slide without any
overrun and with low tension over the thickest point of the hook.
To set the needle thread regulator:
1. Loosen screw (5).
2. Set the needle thread regulator (2).
 The vertical wire (3) serves in conjunction with the scale (4) as adjusting aid (guide value: 2.5).
3. Tighten screw (5).
Information
The needle thread regulator (2) is correctly adjusted if:
The thread take-up spring (1) is pulled down about 1 mm from its upper
final position, when the thread loop (6) passes the maximum hook
breadth.
The length of 1 mm is an approximative guide value. Depending on the
tension of the thread take-up spring it may be higher or lower.

The light beam transmitted by the light barrier (1) is reflected by the exposed reflecting surface (2) of the bobbin hub (3).
The display of the control unit shows a corresponding message.
The seam is safely finished with the thread remaining in the reserve groove.
To use the remaining thread monitor:
1. Turn off the main switch.
2. Change the bobbin
Important
Clean the lenses of the light barrier with a soft cloth after every bobbin change.

5.3 Installing the machine software
NOTICE
Property damage may occur!
The machine software is already installed when the machine is
delivered.
Switch off the machine before connecting the dongle.
Loading a specific sewing software in the DAC classic control unit is possible with the help of the Programmed Dongle. The Programmed Dongle
has a label indicating the machine class and the software version.
Such a loading (booting) may be used in order to provide a single DACclassic control unit with a sewing software (first installation) or to install a
newer machine software (update).
With the delivery of the machine only the test software (allowing the loading of sewing software) is installed in the control unit. The test software
offers no further functions. If the test software gets damaged during the
loading process, it is no longer possible to load a software using a dongle.
In such a case use a PC with a loader cable.
The instructions for the DAC classic control unit is enclosed with the machine.

Characteristics
• Sewing length controlled alternatively by light barrier or by programming
• Seam protection alternatively at seam beginning and seam end through
stitch condensing or bartacking the material and thread chain
• Thread trimming system: Controlled chain trimmer
• High sewing performance and short cycle duration due to DAC classic
in combination with a stepping motor and an additional control unit for
the material feed
• Fully overlapping working method
• Compact, height adjustable sewing unit with transport castors, to be
operated in standing or sitting position
• Positioning station, folder station and sewing station are combined in a
single swivel-mounted unit for easy maintenance and setting access
• Electronic thread monitoring system
• Designed to process spun and monofilament threads
• Integrated setting disc with positioning marks on the hand-wheel for a
rapid and precise control of the machine settings
• A template set adapted to the sewing shape retains and guides the
workpiece
• The template can be easily exchanged; upon ordering the sewing unit,
one or several template sets have to be selected.
• The dart depth depends on its length, the template set and the setting
of the folding table; by adjusting the folding table between 0 and 10°,
the dart depth can be altered
