Baby Lock Sewing Machine Needle Threader Troubleshooting

Is the timing mark on your hand wheel facing straight up to 12:00?

Is your thread properly routed through all numbered guides and secured in the spring plate at position 6?

The timing is off. We'll reset it and test the threader.

1. Touch OK on any error message displayed.
2. Press the needle up/down button once to lower the needle.
3. Press the needle up/down button again to raise the needle to its highest position.
4. Verify the timing mark now faces straight up to 12:00.
5. Activate the needle threader button to test.

We need to check if the needle threader hook is bent or misaligned.

1. Remove the needle by loosening the needle clamp screw.
2. Place a white piece of paper under the needle area for better visibility.
3. Press the needle threader button and immediately turn off the power when it drops.
4. Look at the small hook – it should be centered between the two guide hooks with equal clearance on both sides.

Let's correct the threading path and test again.

1. Press the needle up/down button to position the needle at its highest point.
2. Raise the presser foot lever to open the tension discs.
3. Mount thread with it spooling from underneath the spool, going back.
4. Apply slight tension while routing thread through numbered guides 1 through 5.
5. Hook thread into the spring plate at position 6.
6. Swing thread to the side and trim with thread cutter.
7. Activate the needle threader button.

The hook looks good. Let's verify the spring plate position and reinstall the needle properly.

1. Check if the spring-loaded plate above the thread guide is laying flat – if down, push it from below and lift it back onto the guide plate.
2. Insert the needle with the flat side toward the back.
3. Push the needle all the way up until it stops against the needle bar post.
4. Tighten the needle clamp screw securely.
5. Press needle up/down button to set proper position.
6. Thread the machine following the numbered path and activate the threader.

The hook needs repositioning. We'll try to adjust it carefully.

1. Using precision-point tweezers, access the bottom side of the hook.
2. Gently push the hook spring either right or left to center it between the guide hooks.
3. Verify equal clearance on both sides when viewed from above.
4. Turn the machine back on and initialize the screen.
5. Reinstall the needle fully against the stop post and test the threader.
