10. Pull the bobbin lever (7) up.
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 the winder mode in the softkey menu ( p. 54).
11. Switch on the machine.
12. Press the pedal forwards.
The machine sews and winds the hook thread from the
thread reel onto the bobbin. When the bobbin is filled, the
winding process stops. The bobbin lever moves down. The
cutter is automatically moved into its basic vertical position.
13. Pull off the full bobbin.
14. Tear off the thread behind the cutter (9).

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 te nsi o n.

4.8.1 Setting the needle thread tension
The needle thread tension can only be set using the software
of the OP3000; for detailed information, refer to the chapter
Programming ( p. 45).
4.8.2 Setting the hook thread tension
WARNING
Risk of injury from needle tip and moving parts!
Puncture, cutting and crushing possible.
Switch off the machine before setting the hook
thread tension.
Fig. 14: Setting the hook thread tension (1)

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.

WARNING
Risk of injury from needle tip and moving parts!
Puncture, cutting and crushing possible.
Switch off the machine before setting the needle
thread regulator.
The needle thread regulator determines the tension applied to
guide the needle thread around the hook.
Proper setting
The loop of the needle thread slides at low tension over the thickest
point of the hook.

5.3 Software operating modes
The software of the 867-M PREMIUM has 3 available operating
modes:
• Manual mode (program 000) ( p. 50)
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 (program 001 - 999) ( p. 80)
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/Edit mode ( p. 84)
Programming mode allows the operator to create a new
seam program in a quick and easy manner.
Edit mode can be used to adjust, delete and copy seam
programs.
The individual modes and their uses are explained in detail later on.

Setting: Number of sections in a bartack (Repetitions)
A bartack always consists of several sections. If the sewing direction is changed, a new section is started. The number of sections
in a bartack can be set in this submenu.
Setting: Waiting time at turning point (t Change)
The waiting time at the turning points (for example for a change
of sewing direction) is set at this point. A short waiting time in
milliseconds should ensure consistent seam quality (ornamentalstitch bartack).
Setting: Default stitch length (St.Len.Def.)
If this function is active, the same stitch length is used for the
bartack as the one set in Manual mode. If this function is deactivated, a custom input can be entered.

Programming
Setting: Single stitches per pedal (Pedal Stop)
If this function is activated, each stitch in the bartack can be sewn
individually by pressing the pedal. This function can only be used
meaningfully if the speed is set very low for the bartack.
Setting: Default needle thread tension (Thr.Tens.Def.)
If this function is active, the same needle thread tension is used
for the bartack as the one set in Manual mode. If this function is
deactivated, a custom input can be entered.
Setting: Bartack before the bartack (Catch Backtack)
To ensure a safe sewing start and complete sewing of the start
bartack, an additional bartack can precede the start bartack.
Only the number of forward and backward stitches can be selected. The stitch length cannot be set individually – it corresponds
to the stitch length of the normal start bartack.

Setting: Number of stitches different for 1
section

st
The 1
section of the bartack can be programmed with a different
number of stitches. All subsequent sections have the preset number of stitches from the settings for the start bartack.
Setting: Number of stitches different for last section
(Last Repeti.)
The last section of the bartack can be programmed with a different
number of stitches. All previous sections have the preset number
of stitches from the settings for the end bartack.
This function is useful for the short stitch for the short thread cutter,
for example. In this case, one less stitch is sewn in the last section.
Operating Instructions 667 PREMIUM - 02.0 - 01/2018 61
Programming
Setting: Invert direction (Invert Dir.)
Normally, a bartack starts either with the sewing direction
(forwards – even number of sections) or against the sewing
direction (backwards – odd number of sections), depending on
the number of sections.

of the seam. If the function is activated, the light barrier must detect
a signal to allow the machine to sew. If the function is inactive,
sewing can take place without signal detection.
Setting: Detection of end of material (End)
The signal scan of the light barrier is performed at the end of the
seam. If the function is active, the machine will continue to sew

Setting: Distance after detection of end of mate rial (Distance)
Here, you can set the distance from the detection of the signal to

needle to the light barrier. The path is specified in millimeters and
used by the machine to independently calculate the number of
stitches.
Setting: Number of signal detections (Seams)
Input of the number of signal detections after which the machine
is supposed to continue with the specifically set parameters.
Setting: Filter stitches up to signal detection (Filter)
Loosely woven fabric with stitches may cause the light barrier to
wrongly detect a signal. To prevent this from happening, you enter
the number of filter stitches. This number represents the minimum
number of stitches with signal detection following the 1

detection
of the signal.
5.4.16 Setting the Outputs parameter (Output)
This parameter provides virtual outputs that can be assigned
customer-specific functions. They can be used when customerspecific applications require a signal from the control of the
machine.
These parameters cannot be used unless the virtual outputs have
been assigned to a physical output at the Technician level.
This requires that the parameter Add I/O be configured at the
Technician level; for more details, refer to the explanation in the
