Frequently Asked Questions - Grace BL40A BABY LOCK

How do I thread the Baby Lock Grace BL40A?
Raise the presser foot and turn the handwheel to raise the needle to its highest position. Follow the numbered thread path, use the automatic needle threader by pulling down the lever, and hold the thread tail while releasing.
What type of needle does the Grace BL40A use?
It uses standard household needles (e.g., 90/14 or 80/12). Ensure the needle is compatible with your fabric type and inserted flat side away from you.
How do I wind the bobbin on this machine?
Place the bobbin on the bobbin winder spindle, push it to the right, thread the bobbin winding tension disc, wrap the thread around the bobbin a few times, and press the foot controller. The bobbin will stop automatically when full.
Why is my machine skipping stitches?
Skipped stitches often result from a dull or bent needle, improper threading, or incorrect tension. Replace the needle, rethread both top and bobbin, and adjust tension if needed.
How do I clean and oil my Baby Lock Grace?
Unplug the machine. Remove the needle and presser foot. Open the bobbin cover and clean lint with a brush or small vacuum. Apply a drop of sewing machine oil to the indicated oiling points as per the manual, then run a test on scrap fabric.
What should I do if the machine jams?
Turn off and unplug. Gently turn the handwheel back and forth to release tension. Remove the bobbin case and fabric, clear any thread tangles, and rethread following the manual. Avoid forcing the handwheel.
How do I adjust the stitch length and width?
Use the stitch length dial (typically numbered 0-4) and stitch width dial (0-5) located on the front of the machine. Set them according to the selected stitch pattern indicated on the stitch selection panel.
Does the Grace BL40A have a free arm?
Yes, it has a convertible free arm. Remove the accessory storage box to access the free arm, which is useful for sewing cuffs and sleeves.
Can I use a twin needle with this machine?
Yes, you can use a twin needle (up to 3mm width) for decorative stitches. Insert the twin needle, thread each needle separately, and select the appropriate stitch pattern. Ensure the width does not exceed 3mm to avoid needle breakage.
How do I adjust the presser foot pressure?
The presser foot pressure is pre-set and non-adjustable on this model. If you encounter feeding issues with very thick or thin fabrics, consider using a walking foot accessory or adjusting the fabric layers.

Adjusting the thread tension

The tensions of the upper thread and of the bobbin thread (thread tension) should be adjusted so that they are equal.

If the thread and needle combination is correct for the type of fabric being sewn (according to "Needle types and their uses" (page 26)), the thread tension will automatically be adjusted to the appropriate setting. However, if the preset thread tension does not give the desired result or if you are sewing with special thread or on special fabric, use the thread tension dial to increase or decrease the tension of the upper thread.

■Correct thread tension

The upper thread and the bobbin thread should cross near the center of the fabric. Only the upper thread should be visible from the right side of the fabric, and only the bobbin thread should be visible from the wrong side of the fabric.

Useful Sewing Tips

Various ways to achieve better sewing results are described below. Refer to these tips when sewing.

Trial sewing

After a stitch is selected, the machine automatically sets the stitch width and length for the stitch that was selected.

However, a trial piece of fabric should be sewn since, depending on the type of fabric and stitching being sewn, the desired results may not be achieved. For the trial sewing, use a piece of fabric and thread that are the same as those used for your project, and check the thread tension and stitch length and width. Since the results differ depending on the type of stitching and the number of fabric layers sewn, perform the trial sewing under the same conditions that will be used with your project.

Changing the sewing direction

When stitching reaches a corner, stop the sewing machine.

Leave the needle lowered (in the fabric). If the needle remained up when the machine stopped sewing, press (needle position button).

2 Raise the presser foot lever, and then turn the fabric.

Turn the fabric using the needle as a pivot.
