Sensor buttonhole
Patterns number 23 and 25 to 33 are sensor buttonholes.
The size of a buttonhole is automatically set by placing a
button in the rear of automatic buttonhole foot R.
The button holder of the foot takes a button size of 1 cm
(3/8˝) to 2.5 cm (1˝) in diameter.
When selecting the sensor buttonholes, the LCD screen
advise you to lower the buttonhole lever.
NOTE:
It is sometimes necessary to change buttonhole size
to match certain heavy or specific fabrics and threads.
Make a test buttonhole on an extra piece of the fabric
to check your settings.
The preset width of the buttonhole is suited for
ordinary buttons.
