To thread the Janome 344, raise the presser foot and turn the handwheel to raise the needle to its highest position. Place the spool on the spool pin, and draw the thread through the top thread guide, down around the tension discs, up through the take-up lever, and finally thread it through the needle from front to back.
If stitches are skipping, check if the needle is properly inserted and not bent or dull. Ensure that the machine is threaded correctly, and adjust the thread tension if necessary. Using the correct needle size for your fabric can also help resolve this issue.
Regular maintenance includes cleaning the bobbin area and feed dogs with a small brush to remove lint and dust. Oil the machine as per the manual’s instructions, using sewing machine oil. It's also important to change the needle regularly and have the machine serviced by a professional annually.
Unusual noises can be caused by a lack of lubrication, so ensure the machine is properly oiled. Check for any loose screws or parts, and re-thread the machine to ensure proper setup. If the problem persists, consult a professional technician.
Ensure the feed dogs are raised and clean. Check the presser foot pressure and adjust it if necessary. Also, verify that the stitch length is set correctly and that the fabric is not too thick for the current settings.
To adjust the tension, use the tension dial located on the front of the machine. Lower numbers loosen the tension, while higher numbers tighten it. Test on a scrap piece of fabric until the stitches are balanced between the top and bottom threads.
First, turn off the machine and remove the fabric. Raise the needle and presser foot, then gently remove any tangled threads from the bobbin area. Re-thread the machine and ensure the bobbin is correctly placed in its case.
Use a universal needle for woven fabrics, a ballpoint needle for knits, and a denim needle for heavy fabrics. Refer to the needle size chart in the manual to choose the correct size based on the thickness of your fabric.
To replace the bobbin, remove the bobbin cover, lift out the bobbin, and place a new, wound bobbin into the bobbin case. Pull the thread through the slit and under the tension spring. Replace the bobbin cover and draw the thread up by turning the handwheel.
Ensure the power cord and foot pedal are securely connected. Check that the power switch is turned on and that there is no blown fuse or circuit breaker. If the machine still won't start, it may need professional servicing.
