7.13 Stitch length
The two adjusting wheels on the machine column determine the stitch
length.
The stitch length can be adjusted continuously between 0 and 12 mm.
The adjusting mark (4) on the left on the wheel indicates the stitch length
selected.
Figure 22: Adjusting wheels for the stitch length
To reduce the stitch length:
• Turn the adjusting wheel clockwise.
To increase the stitch length:
• Turn the adjusting wheel counterclockwise.
You can select two different stitch lengths. The upper adjusting wheel (2)
is for the larger stitch length and the lower adjusting wheel (3) is for the
smaller stitch length.
The larger stitch length is switched on using the stitch length key on the
key pad (see Section 7.14 Keypad for quick functions).
If the large stitch length is active, the indicator (1) lights up to the right of
the upper adjusting wheel.
The larger stitch length must not be shorter than the smaller stitch length.
Always select the same or a higher stitch length at the upper adjusting
wheel (2) than at the lower adjusting wheel (3).
The reversing lever on the machine arm reduces the stitch length down to
sewing backwards in the lower end position.
Figure 23: Reversing lever on the machine arm
• Push the reversing lever (1) down slowly.
The stitch length becomes smaller. In the lower end position, the machine
sews backwards with the stitch length selected at the adjusting wheels.

Machine damage possible if the adjusting wheels are turned
using brute force.
The machine is designed in such a way that a lower stitch length
cannot be selected at the upper adjusting wheel than at the lower
adjusting wheel.
Do not attempt to use brute force to select a smaller stitch length at
the upper adjusting wheel.
