Setup

4. Threading the Machine
Proper threading is crucial for good stitch quality. Follow these steps carefully:
- Bobbin Winding: Place a spool of thread on the spool pin. Guide the thread through the bobbin winding tension disc and then around the bobbin several times. Place the bobbin onto the bobbin winder spindle and push it to the right. Press the foot controller to wind the bobbin. Stop when the bobbin is full and push the spindle to the left to disengage.
- Inserting the Bobbin: Open the bobbin cover plate. Insert the wound bobbin into the bobbin case, ensuring the thread unwinds in the correct direction (usually counter-clockwise). Guide the thread through the tension spring and out the bobbin case opening. Close the bobbin cover.
- Upper Threading: Raise the needle to its highest position using the handwheel. Place a spool of thread on the spool pin. Guide the thread through the upper thread guide, down into the tension discs, up and through the take-up lever, and then down to the needle. Thread the needle from front to back.
- Bringing Up the Bobbin Thread: Hold the upper thread lightly. Turn the handwheel towards you to lower and then raise the needle. The upper thread will catch the bobbin thread, bringing a loop up through the needle plate hole. Pull both threads under the presser foot and towards the back of the machine.
Operating the Machine
1. Stitch Selection
The SINGER 4423 offers 97 stitch applications. Use the stitch selector dial on the front of the machine to choose your desired stitch pattern. Refer to the stitch chart on the machine for available options.

2. Stitch Length and Width Adjustment
Adjust the stitch length using the upper dial and stitch width using the lower dial, as indicated on the machine. Experiment with different settings on a scrap piece of fabric to achieve the desired result for your project.
3. Using the Foot Pedal
The foot pedal controls the sewing speed. Press gently for slower speeds and apply more pressure for faster sewing. Release the pedal to stop.
4. Reverse Sewing
To reinforce stitches at the beginning and end of a seam, press and hold the reverse lever (usually located on the front of the machine) while sewing. Release the lever to resume forward stitching.
5. Needle and Presser Foot Replacement
Always use the correct needle type and size for your fabric. To replace the needle, loosen the needle clamp screw, remove the old needle, insert the new needle with the flat side facing the back, and tighten the screw. To change presser feet, raise the needle and presser foot lifter, then press the release button on the back of the presser foot holder. Attach the new foot by aligning it and lowering the presser foot lifter until it snaps into place.
Maintenance
1. Cleaning
Regular cleaning helps maintain your machine's performance.
- Lint Removal: Unplug the machine. Remove the needle, presser foot, and needle plate. Use the provided lint brush to remove lint and dust from the bobbin area and feed dogs.
- Surface Cleaning: Wipe the exterior of the machine with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
2. Oiling
