Programming
Icon Parameter
Stitch length default
If this function is active, the same nee-
dle 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.
Speed in bartack
Single stitches per pedal
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.
Needle thread tension default
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.
Catch bartack
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.
