2. Adjusting the needle thread trimmer
Please turn off the power switch and confirm that the motor has stopped before operation to
prevent personal injuries caused by unexpected start.
(1) Adjusting the thread grasping force of the needle
thread trimmer
If the needle thread trimmer fails to provide consistent
thread grasping force, the needle thread can slip off at
the beginning of sewing.
1) If the thread grasping force of the needle thread
trimmer has reduced, loosen setscrew① and
detach needle thread trimmer②.
2) Slightly bend the top end of thread presser spring
and adjust the contact clearance between presser
spring③ and needle thread trimmer ④to zero.
(2) Installation height of needle thread trimmer
Loosen setscrew of needle thread trimmer and adjust
the installation height of needle thread trimmer
Try to make needle thread trimmer do not touch presser
as far as possible in order to minimize the length of
remaining thread on the needle after trimming.
Note that the presser tilts when sewing a multi-layered
portion of the material. Attach the needle thread
trimmer to slightly raise the installing position of the
trimmer.
When replacing the needle thread trimmer,
make sure that the trimmer normally works
under the needle thread trimmer adjusting
mode (memory switch level 2: K051).
