Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the
sewing machine.
10. Adjustment of the wiper spring
Wiper spring q retains the needle thread after thread
trimming in between wiper w and the wiper spring.
Correct properly the tension of wiper spring q so that
the tension at that time becomes 20 to 30 g (a little
higher tension than that of the bobbin thread coming
out of the bobbin case).
If the retaining of the needle thread is
excessive, the thread may protrude from
the upper side of the button.
