6. To stop, release pressure on the foot controller.
7. Raise the needle to its highest position by turning the handwheel.
8. Raise the presser foot and remove the fabric.
9. Cut the threads using the thread cutter on the machine.

3.6 Changing the Presser Foot

Different sewing tasks require different presser feet. To change the presser foot:

1. Turn off the power and unplug the machine.
2. Raise the presser foot lifter.
3. Press the black button on the back of the presser foot holder to release the current foot.
4. Position the new presser foot so its pin aligns with the groove on the presser foot holder.
5. Lower the presser foot lifter until the foot snaps into place.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your sewing machine.

4.1 Cleaning the Machine

Lint and dust can accumulate in the bobbin area and feed dogs, affecting stitch quality. Clean these areas regularly:

1. Turn off the power and unplug the machine.
2. Remove the needle and presser foot.
3. Remove the needle plate (usually by unscrewing or sliding a latch).
4. Use a small brush to remove lint and dust from the bobbin case area and feed dogs. Do not use compressed air, as it can push lint further into the machine.
5. Reassemble the needle plate, presser foot, and needle.

4.2 Oiling (If Applicable)

The Janome Model 3090 is designed to be largely maintenance-free regarding lubrication for the user. If your machine requires oiling, refer to a specialized service manual or contact a Janome service center. Do not oil parts unless specifically instructed, as this can damage the machine.

4.3 Storage

When not in use, cover the machine with its dust cover to protect it from dust and debris. Store it in a dry, stable environment.

5. Troubleshooting

This section addresses common issues you might encounter. For problems not listed here, please contact customer support.

5.1 Machine Not Starting

• Check Power: Ensure the power cord is securely plugged into both the machine and the electrical outlet.
• Power Switch: Verify the power switch is in the 'ON' position.
• Foot Controller: Ensure the foot controller is properly connected.
• Bobbin Winder: Make sure the bobbin winder spindle is pushed to the left (off the winding position).

5.2 Skipped Stitches

• Needle: Replace the needle. A bent or dull needle can cause skipped stitches. Ensure the needle is inserted correctly.
• Needle Type: Use the correct needle type and size for your fabric.
• Threading: Re-thread the upper thread and re-insert the bobbin, ensuring correct tension.

5.3 Thread Breakage

• Threading: Check if the machine is threaded correctly, both upper and bobbin threads.
• Tension: Adjust the upper thread tension. It might be too tight.
• Needle: A bent, dull, or incorrect needle can cause thread breakage. Replace if necessary.
• Thread Quality: Use good quality thread. Old or poor-quality thread can break easily.
• Lint: Clean the bobbin area and tension discs from lint buildup.

5.4 Uneven Stitches / Looping

• Tension: Adjust the upper and bobbin thread tension. Incorrect tension is the most common cause of uneven stitches.
• Threading: Ensure both threads are correctly threaded through all guides and tension discs.
• Bobbin: Check if the bobbin is wound evenly and inserted correctly.
