REPLACEMENT OF THREADER PIN
If the threader pin (threader spring) is deformed or damaged, then replace it with a new one in
the following procedure.
(1)
Pull down the threader 2 cm or so from its highest position.
(2)
Hold the threader supporter in place.
(3)
Pinch the knob section of the threader pin and pull it out.
(4)
With the pushbutton fully pushed in, carefully insert a new threader pin along the guide
grooves in the pushbutton until the knob is brought into close contact with the pushbutton.
If the threader pin stops halfway, avoid forcibly pushing it in because its end is caught in a
hole inside the threader supporter. In such a case, slightly move the pushbutton vertically or
laterally and carefully push in the pin after smooth insertion is ensured.
(5)
Set the threader to the needle.
(6)
Press the pushbutton and check if the threader pin interferes with the needle eye.
(7) If the threader pin interferes with the needle eye, then adjust the position of the positioning
plate according to “ADJUSTMENT OF THREADER”.
