Set two threads in parallel to the centerpiece of the thread spreading knife, and move the thread trimmer
knife to check the sharpness.
* How to adjust the thread trimmer knife when the thread could not be trimmed
○
Both two threads cannot be cut
• • • Move the thread trimmer knife horizontally towards the thread spreading knife.
○
The right thread cannot be cut
• • • Adjust the thread trimmer knife as twisting rightward.
○
The left thread cannot be cut
• • • Adjust the thread trimmer knife as twisting leftward.
(Caution) When correcting the position, make sure to gradually adjust the position. If too much
force is applied, distortion occurs and adjustment of the knife pressure will become
difficult.
Use a pair of radio pliers for
thread trimming adjustment.
(Caution) When making adjustment, do not touch
the blade of the thread trimmer knife.
Set the threads in
parallel.
