For machines with thread clamp (optional)
12. Insert the thread through the right hole of the guide above
the thread clamp.
13. Insert the thread through the right hole of the guide below
the thread clamp.
Fig. 8: Thread clamp
14. Insert the thread into the thread clamp from the right so that
the thread is held in place inside the hook of the clamp.
The thread is supposed to run through the clamp almost without
touching it and in such a way that it only makes contact with
the guides above and below the thread clamp.
15. Insert the thread through the thread guide (8) on the needle
bar block.
16. Insert the thread through the needle eye (towards the groove)
in such a way that the loose thread end faces the hook.
17. Pull the thread through the needle eye until the loose thread
end has a length of approx. 4 cm with the thread lever (12) at
the highest position.
Important
Check the thread length.
If the loose thread end is too long, the thread may be caught by
the hook and cause a disturbance. If the loose thread end is too
short, the machine cannot start sewing.
Operation
28 Operating Instructions D669 e-con - 00.0 - 06/2023
4.6 Winding the hook thread
The hook thread can be wound on without sewing.
Important
Never use the winder without a bobbin. If using it without a bobbin,
you run the risk of the thread winding itself around the bobbin
shaft, which may cause damage to the winder.
To wind the hook thread:
1. Fit the thread reel on the reel stand.
The unwinding bracket must stand directly above the thread
reel.
2. Feed the thread from the rear to the front through the thread
guide on the unwinding bracket.
WARNING
Risk of injury from needle tip and moving parts!
Puncture, cutting and crushing possible.
Turn off the machine before threading the thread.

from left to right before feeding it clockwise around the pre-
tension (1).

end behind it.
9. Fit the bobbin on the bobbin shaft (5).
10. Turn the bobbin on the bobbin shaft (5) until the drive dog
spring audibly clicks into place in the slot of the bobbin.
11. Pull the winder lever (4) up.
The winding process starts and ends automatically when
the bobbin is full. The winder lever (4) returns to its lower
position.
Information
The hook thread is normally wound on when sewing is in progress.
However, you can also wind on the hook thread without sewing,
e. g. if you require a full bobbin in order to start sewing. For this
purpose, use Bobbin Wind mode in Manual mode ( p. 43).
12. Pull off the full bobbin.
13. Tear off the thread behind the knife (6).
14. Insert the full bobbin into the hook ( p. 31).

Inserting a full bobbin
5. Insert a full bobbin (3) into the bobbin case upper section (2).
6. Feed the hook thread through the slot (4) under the tension
spring (5) into the hole (1).
7. Pull the hook thread approx. 5 cm out of the bobbin case upper
section (2).
The bobbin must rotate in the direction of the arrow when
pulling out the thread.
8. Insert the bobbin case upper section (2) again.
9. Close the hook cover (6).
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 ruffing and thread
breaking.
Proper setting
If the tension of needle thread and hook thread is identical,
the thread interlace lies in the middle of the sewing material.
Adjust the needle thread tension so that the desired seam pattern
is achieved with the lowest possible tension.

Proper setting
The hook thread tension must be set so that the resulting seam
pattern is uniform.
The basic setting for the tension spring is performed as follows:
• When the bobbin case contains a full bobbin it must sink
slowly under its own weight.
The braking spring (1) prevents the bobbin running on when the
thread has been cut.

The software of the control panel offers various operating modes:
• Manual mode
Manual mode is the simplest operating mode. There are no
programs/seam programs and no inputs for individual seam
sections.
Changes to the sewing foot pressure, stroke height, stitch
length, needle thread tension and, also, the activation of
other functions are always implemented immediately.
All the major sewing parameters can be changed manually
during the sewing process.
• Automatic mode
Automatic mode allows for the execution of setups (seam
program comprised of only one seam section) or complex
seam programs (comprising 2 or more seam sections).
Seam programs are divided into individual seam sections.
Each section is assigned its own individual stitch length,
needle thread tension, etc.
• Programming
Programming mode makes it possible to create, adjust or
delete a seam program in a quick and easy manner.
The individual modes and their uses are explained in detail later on.

ters. The following table lists all possible options.
Settings that are more complex and therefore require further
explanation are described in more detail after the table.
Edit segments

Additional values (+)
Additional value stitch
length (+)
The 2nd value for the stitch length can
be switched on using a button on
the push button panel or the tile on
the control panel.
Value range
00.0 - 12.0
(depending on sewing equipment
and subclass)
Additional value sewing foot
stroke (+)
The 2nd value for the sewing foot stroke
can be switched on using a button on
the push button panel, the knee button
or the tile on the control panel.
Value range
05.0 - 09.0 [mm]
Additional value needle
thread tension (+)
The 2nd value for the needle thread
tension can be switched on using a
button on the push button panel or the
tile on the control panel.

Gap (2nd value)
The 2nd value for the gap can be
switched on using a button on the push

Program Cycle
Next program
A subsequent program can be defined.
Input via program number.
Program Cycle
The program is executed as a loop,
which is useful, for instance, for
ornamental stitch seams.
You select the start segment and
the end segment from a program and
define how often you wish the selected
segments to be sewn.
On/Off
Start Segment
Value range 00 – 30
(0 = the cycle starts with the first
segment)
End Segment
Value range 00 – 30
(0 = the cycle ends with the last
segment)
Repetitions
Value range 00 – 99
(0 = the cycle continues until the next
segment is activated manually)
Main Parameter
Needle thread clamp
The needle thread clamp is closed at
the 1st stitch of the seam to ensure that
the needle thread lies on the underside
of the sewing material
Value range
On/Off
Bobbin monitor mode (see p. 107)

Counter Mode
Daily piece counter, can be set to count
either up or down.
Off/Up/Down
Reset
When the daily piece counter is
activated, it must be reset once after
entering a value to ensure it counts
correctly.
Point position
The distance of the needle from
the material can be adjusted to allow
precise positioning of the sewing
material when starting sewing.
The value entered corresponds to the
degree number on the handwheel.

Stitch length The stitch length changes slightly
depending on the speed. For this rea-

at different speeds by the software.
Needle thread tension Depending on the speed, the needle
thread tension can be adjusted at
different speeds by the software.
Sewing foot pressure Depending on the speed, the sewing
foot pressure can be adjusted at
different speeds by the software.

5.8.5.3 Setting the Material thickness detection
parameters
To achieve consistently good sewing results for different material
thicknesses, some parameters can be adjusted specifically to the
material thickness.
Overview of settings modes
The material thickness can be identified in various modes and
responded to depending on the setting. This general explanation
can be applied to the following specific parameters.
Setting mode Description
linear In the linear setting, the size of the parameter
increases or decreases steadily as the material
thickness increases. The increase/decrease of the
parameter depends on the limits set for the minimum
and the maximum material thickness.
2.Value
On/Off
If a certain material thickness is exceeded, the
2nd value of the parameter is activated. If the material
thickness then falls below this level again, it switches
to the base value for the parameter.
2. Value On If a certain material thickness is exceeded, the
2nd value of the parameter is activated. If the material
thickness then falls below this level again, it does
NOT switch to the base value for the parameter.
Only after finishing the seam by cutting the thread is
the base value for the parameter set again.
