6.14.2 With the buttons
Button Function
1 Sew backwards manually
The machine sews backwards for as long as the button is held down.
2 Position the needle in the upper or lower position.
The function of the button can be set with the parameter F-242 (DA321):
1 = needle high/low
2 = needle high
3 = one stitch
(The factory default for delivered machine is 1.)
3 Invoke or suppress the start/final bartacks
In general, if the start and final bartacks are activated, then the next bartack is deactivated
by pressing the button.
If the start and final bartacks are deactivated, then the next bartack is activated by pressing
the button.
4 Switching the stitch length
The function of the button can be defined with parameter F-250 (DA321):
1 = pressing the button switches the stitch length between two pre-set values.
4 = pressing the button changes the stitch length to a lower value. A stitch is then sewn and
the machine reverts back to the original (larger) stitch length.
5 Activating and deactivating the supplementary thread tension (see chapter 6.5)
The button background is illuminated when the supplementary tension is activated.
(The tension discs are closed.)
By pressing the button the supplementary tension is deactivated and the button is not
background lit (the tension discs are opened).
LED Function
7 and 8 Display empty bobbin for residual thread monitor (left/right bobbin)
9 LED display “Power On”
Example for By adjusting the screw 10 (located under button 1), you can assign the function
adjusting a button of button 1 to the lever (6).
(for example, 10): - Select the function (for example, 1 = sew backwards manually)
- Turn screw 10 (located under button 1) clockwise 90° (the slot is then positioned vertically).
The function can now be invoked by both button 1 and the lever (6).
Caution!
Be sure to deactivate the existing function before changing
the function of lever 6.
