Refer to the manual’s diagrams for clear visuals of each component and their functions.
Setting Up the Work Area
Create a comfortable and efficient workspace by placing the Singer 4423 on a sturdy, flat surface, such as a sewing table. Ensure good lighting to see your work clearly.

Consider organizing accessories in nearby storage bins or trays. A clean, clutter-free area helps prevent mistakes and speeds up your sewing process. Always unplug the machine when not in use for safety.
Threading the Machine
Threading the Singer 4423 is straightforward. Begin by placing the thread on the spool pin. Guide the thread through the tension discs, ensuring it clicks into place. Pass the thread through the take-up lever and then through the needle’s eye. Leave a small tail at the end. For the bobbin, wind the thread evenly, then insert it into the bobbin case. Pull the thread gently to seat the bobbin properly. Avoid over-tightening and keep the tail long enough to prevent tangling. Use the built-in cutter to trim excess thread. Always test the thread tension before sewing to ensure smooth stitching.
Oiling and Maintenance Preparation
Regular maintenance is crucial for the Singer 4423’s performance. Locate the oil ports, typically found near the bobbin area and handwheel. Use only high-quality sewing machine oil to prevent damage. Apply a few drops to each port, then gently turn the handwheel to distribute the oil evenly. Allow the machine to sit for a few minutes to let the oil settle.

Press the buttonholes after sewing to create a crisp finish. Test the stitch on scrap fabric first to ensure proper tension and length. Use the buttonhole foot for precise alignment.
