(4) Pressure of thread clamp spring
The pressure of the thread clamp spring should be kept to
a minimum as long as the thread can be caught
comfortably after trimming.
A. Loosen the nut ⑬.
B. After trimming, use the screw ⑭ to adjust the pressure
so that the thread clamp spring ⑫ and the movable
trimming knife ③ can catch the thread.
(5) Adjusting thread pull-off hook unit
To shorten the thread after trimming, lift the thread pull-
off hook ⑮ up and vice versa.
[ Caution ]
A. Use as much thread stroke as possible. If there is not
enough stroke, trimming thread may not be caught
after trimming.
B. When using flexible thread such as wool thread, insert
it into the eyelet ⒃.
