To thread the Brother ST371HD, raise the presser foot and turn the handwheel toward you until the needle is at its highest position. Follow the threading path indicated on the machine, making sure the thread passes through the take-up lever. Finally, thread the needle from front to back.
Ensure you are using the correct needle size and type for your fabric. Check that the needle is not bent and is inserted correctly. Additionally, verify that the thread tension is properly adjusted and that you are not sewing through excessively thick layers without the appropriate needle.
To adjust the tension, use the tension dial located on the top of the machine. For lighter fabrics, decrease the tension, and for heavier fabrics, increase it. Test on a scrap piece of fabric to ensure the stitch is balanced.
Regularly clean the machine by removing lint and dust from the bobbin area and feed dogs using a small brush. Oil the machine as specified in the user manual, and have it serviced by a professional annually to maintain optimal performance.
Ensure that the feed dogs are engaged. If your machine has a drop feed lever, make sure it is in the correct position. Check that the presser foot is down and that you are using the appropriate presser foot for your fabric type.
Raise the presser foot lever, then press the black button located at the back of the presser foot holder to release the current foot. Position the new presser foot under the holder, lower the presser foot lever, and it should snap into place.
Stop sewing immediately and turn off the machine. Check for any trapped thread or fabric in the bobbin area and ensure the needle is not bent. Clean the machine of any lint buildup and re-thread both the upper thread and bobbin.
Check that you are using the correct needle size and type for the fabric. Ensure the needle is not dull or bent and is inserted correctly. Re-thread the machine, making sure the thread is properly seated in the tension discs.
Yes, the Brother ST371HD is designed to handle thick materials. Use a suitable heavy-duty needle and adjust the presser foot pressure if necessary. Sew slowly over thick seams to prevent needle breakage.
Turn off the machine and unplug it from the power source. Wait for about 30 seconds before plugging it back in and turning it on. This can help resolve minor electronic glitches.
