7. CORRECT USE
7-1. Selecting the needle and thread
Refer to the table at right for details on which needle and
thread to select.
Note:
Use buttons which have a hole diameter that is
greater than the value given in the table, to ensure
that the needle does not touch the button.
7-2. Installing the needle
CAUTION
Turn off the power switch before installing the
needle, otherwise the machine may operate if the
foot switch is depressed by mistake, which could
result in injury.
Loosen the set screw (1), insert the needle (2) as far as it
will go so that the groove is facing toward you, and then
tighten the set screw (1).
7-3. Threading the upper thread
CAUTION
Turn off the power switch before threading the thread, otherwise the machine may operate if the foot switch is
depressed by mistake, which could result in injury.
Thread the upper thread correctly as shown in the illustration below.
* If the tension release lever (1) is raised in the direction of the arrow, it will be easier to open the tension disc (2) and pull the
thread through.
