7.11 Sewing foot pressure
The adjusting wheel at the top left determines the contact pressure of the
sewing foot on the material to be sewn. The pressure can be adjusted con-
tinuously by turning the wheel.

To increase the sewing foot pressure:
• Turn the adjusting wheel (1) clockwise.
To reduce the sewing foot pressure:
• Turn the adjusting wheel (1) counterclockwise.
7.12 Sewing foot stroke
The two adjusting wheels in the middle of the machine arm determine how
high the sewing feet are raised during sewing. The height can be adjusted
continuously on a scale from 1 to 9 by turning the wheels. With 1 the sew-
ing foot is raised the least and with 9 it is raised the highest.
