Speed controller F controls the speed when the thread
trimming knife holder projects.
Speed controller G controls the speed when the thread
trimming knife holder retracts.
If the speed is too fast, the knife holder will be greatly
shocked. This will cause trouble such as a thread is
trimmed before it is caught in the knives or it is not
clamped correctly by the thread clamp.
If screw F is too loosened, the holder will protrude too
fast and then the position of the movable knife will
become unstable, causing cutting error.
If screw G is too loosened, the holder will retract too
fast and then a looper thread may not be held properly.
