MAXIMUM LEFT NEEDLE DESCENT ALIGNMENT

ADJUSTMENT
1. Move the feed drop slide to the right to put the feed dog in the down position. Lay paper under the presser
foot.
2. Turn the selection dial, turn the Zigzag dial to the maximum, set to Zigzag sewing, and turn the balance
wheel so that the needle falls to the left.
3. Turn the balance wheel and drill a small hole in the paper with the tip of the needle for left needle descent.
4. Turn the selection dial and left straight line sewing.
5. Loosen the screw securing the eccentric nut.
6. Adjust the eccentric nut so that the tip of the needle comes to the position of the hole drilled in 3.

Adjustment Points
6. In left straight line sewing, when the eccentric nut is turned to the right, the needle descent moves to the
left.
7. When fastening the eccentric nut with the screw, install the screw with the eccentric nut held in place with
a box driver so that the positioning is not lost.
