16.3 Setting the cutting pressure
The shape of the thread-pulling knife automatically creates the required cut-
ting pressure as soon as the thread-pulling knife and counter-blade make
contact.
Correct setting
In the rest position, the hook thread clamp makes contact with the thread-
pulling knife without any pressure being applied. Any 2 threads with the
greatest strength used for sewing can be neatly cut simultaneously.
Faults caused by an incorrect setting
• Increased knife wear when the pressure is too great
• Problems when sewing on if the hook thread clamp is too high
• Problems in cutting the thread
Cover
• Throat plate slide (
