There could be several reasons why your Singer sewing machine is not grabbing the bobbin thread. Here are some possible causes and their solutions:
1. Incorrectly threaded machine: Check the threading of both the top thread and the bobbin thread. Make sure the threads are properly placed and threaded through all necessary guides and tension discs as per the machine's manual.
2. Bent or damaged needle: A bent or dull needle can cause issues with thread grabbing. Replace your needle and ensure that it is the correct size and type for the fabric you are using.
3. Improperly wound bobbin: Ensure that the bobbin is wound smoothly and evenly without any tangles or loose threads. Make sure the bobbin is inserted correctly and rotates in the right direction.
4. Tension issues: Incorrect tension settings can lead to the machine not picking up the bobbin thread. Adjust the tension dial as per the machine's manual recommendations and perform some test stitches on scrap fabric to find the correct tension.
5. Dirt or lint buildup: Accumulated dust, lint, or thread particles in the machine's bobbin area can hinder proper thread pickup. Clean the bobbin case, shuttle, and feed dogs using a small brush or compressed air. Regular cleaning and maintenance are essential for smooth operation.
6. Incorrect bobbin type: Ensure that you are using the correct type of bobbin recommended for your Singer sewing machine model. Different machines may require specific bobbin types, so refer to your machine's manual for guidance.
If you have tried these troubleshooting steps and your Singer sewing machine is still not grabbing the bobbin thread, it may be necessary to consult a professional sewing machine technician for further inspection and repair.

To set up a straight stitch on a Singer Heavy Duty 4432 sewing machine, follow these steps:
1. Plug in the machine and turn on the power.
. Place your fabric under the presser foot, ensuring that it is lined up straight and the needle is positioned where you want to start stitching.
3. Select the appropriate needle and thread for your fabric.
4. Set the stitch length dial to "2" or the desired stitch length for a regular straight stitch.
5. Set the stitch width dial to "0" or the central position for a straight stitch. This will ensure the needle moves only up and down in a straight line.
6. Adjust the tension dial according to the thread and fabric being used. Generally, a moderate tension setting between 4 and 5 should work for most fabrics.
7. Lower the presser foot by using the lever located behind it.
8. Hold the thread tails with your left hand, and gently turn the handwheel (located on the side of the machine) towards you until the needle goes down into the fabric and back up, creating a loop.
9. Slowly start pressing the foot pedal to begin sewing. Guide the fabric evenly and keep a steady pace.
Remember to refer to your machine's user manual for specific instructions and troubleshooting tips if needed.
