7-7. Adjusting the work clamp lift amount
1. Turn on the power and set the sewing machine to the home position.
2. Check that memory switch No. 002 (Work clamp height when treadle is at neutral) is 10 mm. (If it is not set to 10 mm, set it
to 10 mm.)
3. Place a 10 mm gauge under the work clamp (1) and then loosen the set screw (2) to make the adjustment.
* Adjust the lift amount (including the play in the work clamp (1) and the pin (3) to 10 mm. If it is set to more than 10 mm, the
work clamp will start lifting before lower thread trimming is complete, which may result in thread trimming errors.
Furthermore, it may also cause the presser foot lifter pulse motor to go out of step.
