on the key pad (
When the larger stitch length is active the stitch length button (4)
on the keypad on the machine arm lights up.
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 (1) than at the lower adjusting wheel (2).
ATTENTION
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.
The stitch adjustment lever on the machine arm reduces the stitch
length down to sewing backwards in the lower end position.
