4.9.3 Setting the sewing foot pressure
The adjusting wheel at the top left of the machine arm determines
the contact pressure the sewing foot exerts on the sewing material.
The pressure can be adjusted continuously by turning the adjust-
ing wheel.
The correct pressure depends on the sewing material:
• Lower pressure for soft materials, e.g. cloth
• Higher pressure for hard materials, e.g. leather
Proper setting
The sewing material does not slip and is correctly transported.
Disturbance from incorrectly set sewing foot pressure
• Excessively high pressure: Tearing of the sewing material
• Excessively low pressure: Slipping of the sewing material
