● When the scissor is advancing, the thread trapper must first trap and hold the threads on
the scissor ( if necessary adjust the thread trapper as required after loosening retaining
screw 4 ).
● As the process continues, both the bobbin thread and the part of the thread loop closest
to the scissor which is held by the catching lug must be cut reliably.
● If the threads are not cut or not cut cleanly check chapter 13.07.14 Scissor drive bar
again.
● Carry out a check in accordance with the requirements.
