The driven part stopper is a safety device so that interference is
prevented between the needle and the moving knife even though the
roller comes off the thread trimming cam when any unexpected problem
(such as a service interruption) occurs.
1. In the state that the thread trimming device is not in action, adjust
two driven part stopper setscrews so that the gap length becomes
0.3mm between the notch of the camís driven part and the camís
driven part stopper .
2. Adjust two driven part stopper setscrews so that the gap length
becomes 1mm between the notch of the camís driven part and
the camís driven part stopper when the thread trimming solenoid
is moved in the direction of the arrow.
