11-2-1. Replacing the stopper

If using the presser foot, needle plate and feed dog for a zigzag width of something other than 8 mm, needle breakages may

occur when the sewing machine is operating, so be sure to limit the zigzag width and replace the stopper as described

below.

* Depending on specifications, some sewing machines may have a stopper for sizes other than 8 mm installed as a standard

part. In such a case, check the size by means of dimension A and the color.

 If using the optional presser foot and needle plate for a zigzag width of 5 mm, replace the stopper with one for 5 mm

(black).

 If using the special-order presser foot and needle plate for a zigzag width of 3 mm, replace the stopper with one for 3 mm

(blue).

 If using the optional presser foot and needle plate for a zigzag width of 10 mm, replace the stopper with one for 10 mm

(white, A=18 mm)

1. Remove the two screws (1), and then remove the stopper

plate (2).

2. Remove the stopper (3) which is inserted into the stopper

plate (2), and then install the stopper (3) which matches

the presser foot and needle plate.

3. Install the stopper plate (2) to the machine head, and

then securely tighten the two screws (1).

4. Turn on the power.

5. Set the zigzag width to the maximum width for the gauge

parts.

6. Turn the machine pulley by hand and check that the

needle does not touch any of the needle holes in the

gauge parts, and that the needle bar does not touch the

stopper (3).

Limiting the zigzag width (added function using memory switches)

If using a presser foot and needle plate for a zigzag width of something other than 8 mm, problems such as the needle bar

touching the stopper may occur if the zigzag width is set by mistake to be larger than the needle hole width of the presser foot

and needle plate.

In order to prevent operation panel setting errors such as this, change the memory switch settings to match the needle hole

width of the presser foot and needle plate.
