13.05.11 Cutting test
Requirement
The knife must stand parallel to the thread catcher and both threads must be reliably cut.
Set the needle bar at b.d.c. and operate solenoid core 1.
Turn balance wheel (sewing direction) until thread catcher 2 is in its front position.
Take a double piece of thread, pull it into the cutout of thread catcher 2 and turn the ba-
lance wheel farther to make a cutting test.
Check that both threads are reliably cut.
If necessary, re-adjust thread catcher 2, see Chapter 13.05.07 Lateral position of the
thread catcher.
