Needle Depth Check/Adjustment
Setting needle depth is one of the basic operator adjustments required to achieve
good sewing quality. The needle depth setting is the relationship between the eye of
the needle and the hook when the needle is at its lowest point. Because of the wide
range of acceptable needle types, the distance between the blunt end and the eye
of the needle may vary enough to cause missed stitches or cut threads if the needle
depth is not absolutely correct. Follow these steps to adjust the needle depth:
1. Remove the needle case cover from the needle case.
2. Remove the center table section from the peripheral.
3. Remove the bobbin case from the rotary hook assembly.
4. Press the [ALT][
⇐
] keys to move to needle #1 (except EMC 1 and ADV 18).
5. Press the [MENU] key until the LCD displays: HEAD TIMING MENU.
6. Press the [ENTER] key and the LCD will display: HEAD TIMING ON.
7. Press the [ALT][

] keys and the LCD will display: GO TO HEADUP.
8. Press the [ALT][
⇐
] keys and the LCD will display: ONE REVOLUTION.
9. Press the [ALT][
⇓
] keys and the LCD will display: NEEDLE DEPTH. This
moves the needle to its lowest point as shown in Figure 3-2.
