16.3 Setting the cutting pressure

The shape of the thread-pulling knife automatically creates the required
cutting pressure as soon as the thread-pulling knife and counter blade
make contact.
Proper setting
In resting 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.
Disturbance
• 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
• Open the throat plate slide ( p. 21)
