To thread the Singer CE-250, first raise the presser foot and turn the handwheel toward you to raise the needle to its highest position. Follow the threading path indicated on the machine, ensuring the thread passes through each guide and the tension discs before threading the needle.
If the machine is not picking up the bobbin thread, ensure the needle is inserted correctly and not bent. Re-thread the machine, checking the bobbin case for correct insertion and that the bobbin is wound evenly.
To change the needle, turn off the machine, raise the needle to its highest position, and loosen the needle clamp screw. Remove the old needle, insert a new one with the flat side facing the back, and tighten the clamp screw securely.
Regular maintenance includes cleaning lint from the bobbin area, oiling the machine as per the manual's instructions, and checking for thread or fabric debris in the feed dogs. It's also important to use good-quality thread and needles.
Skipped stitches can be resolved by ensuring the needle is not damaged and is the correct type for the fabric. Re-thread the machine, ensuring the thread is seated in the tension discs, and check that the bobbin is correctly inserted.
If the fabric is not feeding, ensure the feed dogs are engaged and not lowered. Check that the presser foot is down and adjust the stitch length setting if necessary.
Tension can be adjusted using the tension dial located on the front of the machine. For straight stitching, set the tension between 3 and 5. For fine or delicate fabrics, a lower tension may be necessary.
Unusual noises may indicate the need for cleaning or oiling. Ensure that the machine is properly threaded, the bobbin is correctly placed, and that there is no thread tangled in the bobbin area.
To use the embroidery function, attach the embroidery unit, select the desired design on the machine's display, hoop the fabric securely, and follow the prompts on the screen to begin embroidery.
To install software updates, connect your machine to a computer via USB, download the update from the Singer website, and follow the installation instructions provided to ensure your machine is up to date.
