Brother PS-3700 F.A.Q.

How do I thread the Brother PS-3700 sewing machine?

To thread the Brother PS-3700, first raise the presser foot and turn the handwheel towards you to raise the needle to its highest position. Place the spool of thread on the spool pin and guide the thread through the threading path as indicated in the user manual, ensuring it passes through the tension discs and the take-up lever. Finally, thread the needle from front to back.

What should I do if the needle keeps breaking on my Brother PS-3700?

If the needle keeps breaking, ensure you are using the correct needle size and type for the fabric. Check for any bent needles and replace them if necessary. Make sure the needle is installed correctly and that the tension settings are appropriate for the fabric type. Also, ensure the presser foot is securely attached.

How can I adjust the tension on the Brother PS-3700?

To adjust the tension, locate the tension dial on your sewing machine. For tighter tension, turn the dial to a higher number; for looser tension, turn it to a lower number. Test on a scrap piece of fabric to ensure the stitch quality is as desired.

Why is the fabric not feeding properly on my Brother PS-3700?

If the fabric is not feeding properly, check if the feed dogs are lowered or if there is lint or debris blocking them. Ensure the presser foot is down, and if necessary, adjust the presser foot pressure according to the fabric thickness.

What maintenance does the Brother PS-3700 require?

Regular maintenance includes cleaning the bobbin case area to remove lint, oiling the machine as recommended in the manual, and checking the needle for sharpness or damage. It's also important to keep the machine covered when not in use to prevent dust accumulation.

How do I set up the Brother PS-3700 for quilting?

For quilting, you may want to use a walking foot to help feed the layers of fabric evenly. Adjust the stitch length to a longer setting and consider using quilting thread and needles designed for thicker layers. Engage the feed dogs and adjust the tension as needed for your quilt sandwich.

What should I check if the machine is skipping stitches?

If the machine is skipping stitches, ensure the needle is not bent or dull and that it is the correct size for the fabric. Re-thread the machine, ensuring the thread is correctly placed through the tension discs and the take-up lever. Check that the bobbin is correctly inserted and wound evenly.

How can I troubleshoot an uneven stitch on the Brother PS-3700?

Uneven stitches can be caused by incorrect tension settings, so check and adjust the upper tension. Ensure the thread is correctly threaded and that the bobbin is inserted properly. Also, verify the needle size and type are appropriate for the fabric.

Can I use twin needles on the Brother PS-3700, and how?

Yes, you can use twin needles on the Brother PS-3700. Make sure the machine is set to a straight stitch and that the width is not too wide, as it can break the needles. Use two spools of thread and thread them through the machine as you would for a single needle, then thread each needle separately.

What are common reasons for thread bunching under the fabric on the Brother PS-3700?

Thread bunching, or "bird's nesting," can be due to incorrect threading, so re-thread the machine, ensuring the thread is through all guides and the tension discs. Check the bobbin is wound evenly and inserted correctly. Adjust the upper thread tension if needed.
