Operating Instructions 669 PREMIUM - 00.0 - 11/2016
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 select-
ed. 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
(First Repet.)
The 1st section of the bartack can be programmed with a different
number of stitches. All subsequent sections have the preset num-
ber of stitches from the settings for the start bartack.
Setting: Invert direction (Invert Dir.)
Normally, a bartack starts either with the sewing direction (forwards
– even number of sections) or against the sewing direction (back-
wards – odd number of sections), depending on the number of
sections.
Setting this parameter inverts the sewing direction of the bartack.
