How to sew a buttonhole
Choose Buttonholes from the main menu and select the buttonhole
of your choice. For this example we have chosen buttonhole no. 47.
The most important settings are visible on the screen. There are three
different ways of sewing a buttonhole: automatically, programmed or
manually.
Automatic buttonhole
Enter the buttonhole length directly on the screen by touching the +
and - icon on the Stitch elongation icon (A). Enter the length of the slit
of your buttonhole. Start to sew your buttonhole by pressing the foot
control. The buttonhole will be sewn automatically.
Programmed buttonhole
You can program a buttonhole while sewing.
1. Activate the buttonhole program by touching the prog icon (B).
2. Sew until you reach the buttonhole size you want and press the
reverse button. The machine sews in reverse and the second bartack
and cuts the threads.
3. The prog icon changes into this (C) icon. You can repeat the
programmed buttonhole as many times as you want.
4. If you want to clear the size of the buttonhole, touch the prog icon
again.
Manual buttonhole
If you touch the Manual icon (D) you will determine where the last
bartack is sewn.
1. Set the length of the buttonhole by touching the Stitch elongation
icon. The machine will sew the fi rst column, the fi rst bartack and
the second column.
2. After having sewn half of the second column, the machine slows
down. When it is time to do the second bartack, touch the reverse
button and the machine start making the bartack.
Note: The machine will not store the manual buttonhole.
How to balance a buttonhole
Start by sewing a sample of the buttonhole. If you fi nd that one of the
columns are longer than the other you can change the balance of the
buttonhole. Touch the balance icon (E) and a popup appears. Touch the
+ and - buttons (F) to change the buttonhole. You should change the
buttonhole so that it looks like your sewed out sample. The machine
will then correct the buttonhole automatically.
Note: If you would like to sew a buttonhole longer than the 5A foot (50mm) you can sew
without the sensormatic guide but with the 1A foot. To get a perfect result without the
sensormatic guide it might be necessary to balance the buttonhole.
