Change the set value of memory switch U60 so that needle thread can be neatly sewn in accordance
with the sewing conditions. In case of increasing the set value, be careful of the interference with
the longitudinal guide.
6. ADJUSTING THE LENGTH OF REMAINING NEEDLE THREAD
It is the standard to adjust the length of remaining needle thread to a short one so that the clamped thread can
be neatly rolled. Adjust the length of needle thread to clamp to a short one in the following procedure and rolling
of the needle thread at the start of sewing can be facilitated. It is possible to roll the thread up to sewing length of
approximately 20 mm.
(There is a case where rolling may not be stabilized even in case of 20 mm or more in accordance with the sewing
conditions.)
