When the treadle is depressed, the sttiches are sewn at the length that has been set using
the stitch length dial (1).
3
When the treadle is depressed backward, end backtacking is carried out and then the
sewing machine stops in the needle up position.
(The sewing machine operates at a speed of 1,200 rpm when sewing end backtack
stitches.)
(For the 8560A, thread trimming is carried out automatically and then the sewing machine
stops in the needle up position.)
NOTE:
•
If the treadle is depressed backward before sewing the number of start backtack
stitches is complete, end backtacking will not be carried out.
•
If the indicator of the thread trimming lock key is illuminated, the sewing machine will
stop in the needle up position without thread trimming being carried out (for the
8560A).
<Turning the end backtack function on and off>
The condition changes as shown below each time the end backtack key e is pressed.
The stitch length for section C is adjusted by means of
the condense dial (2), and the stitch length for section
D is adjusted by means of the stitch length dial (1).
<When the condense dial is
set to a "-" (minus) value>
<When number of stitches
for section D is "00">
