Determining your own buttonhole seam length
and bartack
When you press right (4)
program key (22) the
buttonhole symbol appears at the right side of
program 91 and both segments will flash (Fig 1)
Before beginning the buttonhole pull the runner
of the buttonhole foot fully to the front.
• Sew the first buttonhole seam at the length
required (Fig 2a).
• Press the tie-off/buttonhole" key 19 (Fig 2)
Now, only the left upper segment of the but
tonhole symbol is flashing (Fig. 3) The
machine then automatically sews the first bar-
tack and the return seam (Fig 2b). Shortly
before the end of seam the machine sews
slowly, stitch by stitch, in order to draw atten
tion to the last bartack. One zigzag stitch
before the end of the first buttonhole seam
press key 19 again. The second barlack is now
sewn and tied off (Fig 2c) (Both segments of
the buttonhole symbol are oft, Fig. 4).
• Now the buttonhole is stored. Without having
to actuate further keys. all following button
holes can be sewn automatically
Adjusting the density of
buttonhole seams
With stitch-length keys 7 the buttonhole seams
can be set more densely or loosely.
The stored buttonhole density is 1.5 mm.
Make a sample buttonhole first.

For every type of fabric, the corresponding but

For heavy materials select a wide buttonhole and
for light materials a narrow one With stitch width

Note:
For sewing buttonholes on knitted or very thin
materials we recommend sewing foot No. 1 A
and dual feed.

"tie-off/buttonhole" key 19 to switch from fully
automatic to semi-automatic during sewing: one
segment flashes (Fig. 3) and you can determine

A garment may consist of different numbers of
fabric plies, e g the buttonhole strip may consist
of three plies and the collar stand of six—owing to
the folded seam edge In this case it is necessary
to program the buttonhole for varying numbers of
fabric plies in order to maintain the same button
hole length as on the three ply buttonhole strip
