To thread the Brother BB370, start by raising the presser foot and turning the handwheel towards you until the needle is at its highest position. Place the spool on the spool pin and secure it with the spool cap. Follow the threading path as indicated on the machine, passing the thread through the thread guide, tension discs, and needle bar thread guide. Finally, thread the needle from front to back.
If the stitches are skipping, first ensure the needle is correctly installed and not bent or dull. Use the right needle size and type for your fabric. Check the threading of the machine, as improper threading can cause skipped stitches. Finally, verify the tension settings and adjust if necessary.
To clean your Brother BB370, first unplug the machine. Remove the needle plate and clean any lint or debris using a small brush or vacuum attachment. Oil the machine as per the user manual's instructions, usually focusing on the shuttle race area. Regularly change needles and use a dust cover to protect the machine when not in use.
If the fabric is not feeding properly, ensure the feed dogs are raised. Check that the presser foot is down and the correct pressure is applied for the fabric type. Clean any lint from the feed dog area. If the problem persists, consider adjusting the stitch length or seeking professional servicing.
To adjust the tension on the Brother BB370, use the tension dial located on the front of the machine. A higher number increases tension, while a lower number decreases it. Test on a scrap piece of fabric to find the appropriate tension setting for your project. The ideal setting ensures balanced stitches without puckering or loose threads.
The Brother BB370 sewing machine uses standard home sewing machine needles. The needle type and size depend on the fabric. Use ballpoint needles for knits, sharp needles for woven fabrics, and heavy-duty needles for thicker materials. Always refer to the fabric guide for specific recommendations.
If you encounter bobbin winding issues, ensure the bobbin is correctly placed on the winder and the thread is passed through the appropriate guides. Make sure the machine is set to bobbin winding mode and the bobbin winder shaft is pushed to the right. Check for any tangles or obstructions in the thread path.
Unusual noises may result from incorrect threading, a bent needle, or lint accumulation. First, re-thread the machine and replace the needle if necessary. Clean the bobbin area and the feed dogs. If the noise persists, the machine might need servicing to check for mechanical issues.
To change the presser foot on the Brother BB370, first raise the needle to its highest position. Lift the presser foot lever to release the current foot. Align the new presser foot with the presser foot holder and lower the presser foot lever to snap it into place. Ensure it's securely attached before sewing.
To fix tension issues, first re-thread the machine, ensuring the thread is correctly seated in the tension discs. Adjust the tension dial gradually and test on a fabric scrap. Make sure to use the appropriate needle and thread for the fabric type. If problems continue, consult the user manual for specific tension settings.
