5.12 Setting the sewing foot pressure
The adjusting wheel (1) on the machine head determines the
contact pressure of the sewing foot on the material to be sewn.
The pressure can be adjusted continuously by turning the wheel.
Correct setting
The material being sewn does not slip and is correctly transported.
The correct pressure depends on the material to be sewn.
Important: The upper transport foot must lie on the transporter
when checking the sewing foot pressure.
Faults due to incorrectly set sewing foot pressure
• Excessively high pressure: Tearing of the material being
sewn
• Excessively low pressure: Slipping of the material being
sewn
