16.4 Setting the counter-blade
Fig. 63: Setting the counter-blade
Proper setting
The thread must be reliably cut using little pressure. The pressure is built
up starting at the marking (2).
Any 2 threads with the greatest strength used for sewing can be neatly cut
simultaneously.
1. Turn the handwheel until the thread-pulling knife (1) can be swung out
after the latch is triggered.
2. Swing out the thread-pulling knife (1) manually. To do this, press the
clamp with the roller (3) against the control cam (4).
3. Insert 2 threads into the thread-pulling knife (1).
4. Turn the handwheel until the cutter swivels down.
5. Check whether the sewing threads have been cleanly cut and pressure
is built up starting at the marking (2).
Faults caused by an incorrect setting
• Increased knife wear when the pressure is too great
• Problems in cutting the thread
Risk of injury!
Risk of crushing injuries and stab wounds from
sharp and moving parts.
Switch the sewing machine off before you check
and set the counter-blade.
