1.
While the sewing machine is stopped, loosen the set screw (3) and move the thread wiper arm assembly (4)
up or down to adjust so that the clearance between the tip of the needle and the top of the wiper is 2 ± 0.5
mm when the thread wiper connecting rod lever (1) is pushed up and the thread wiper (2) has passed below
the needle.
* This adjustment should be made while the sewing machine is stopped. Be careful not to turn the machine
pulley, otherwise the tip of the needle will move.
2. Loosen the two bolts (5) and move the cylinder cover (6) up or down so that the thread wiper is
approximately 38 mm from the needle when it is at the standby position.
