1.Press the P key and adjust the Y-sensor setting plate e so that the needle q is aligned with the home position (X=0, Y=0) of the H-position standard plate w.

2.Press the P key again to make sure that the needle q is aligned with the home position (X=0, Y=0) of the H-position standard plate w.

3.Attach the Y-sensor setting plate e to the Y-home position bracket r using the bolt t.

5.Press the P key to be out of the program mode, and turn off the power.

6.Replace the H-position standard plate w with the work clamp.

Note: When adjusting the Y home position, be sure to set the clearance between the Y-driving shaft y and the surface where the sensor u is activated to 0.1 - 0.5 mm. If the clearance is too great, an error in home position detection may occur because the temperature of the sewing machine rises during sewing operation.
