Caution Risk of Injury!
Set the thread gripper and thread deflector only in the "Safe Stop"
position or with the machine turned off.
Rule and Control
The deflector 3 is mounted above the fixed knife 2. It prevents the
looper thread end and the gimp from lying between knife 2 and the
back of the thread catcher 7. Instead, they will both be guided next to
or into the thread catcher.
If this does not occur, the knife can be pushed away and doesn't cut.
The cutting pressure can only be set so high as is necessary to
securely cut the threads.
The thread catcher must move past the thread grippers 5 as closely as
possible without the thread catcher touching the thread grippers.
