・ At the time of thread trimming, the thread tension is
loosened and tension is applied by the pretension (1)
only.
・ The standard upper thread trailing length is 25 to 30 mm.
・ If the tension of the pretension (1) is increased, the
lengths of the threads trailing from the needle tips will be
reduced; if the tension is reduced, the lengths will be
increased.
Adjust by turning the pretension (1).
