4. ഓപ്പറേഷൻ

Once the bobbin case is installed, follow these steps to prepare it for sewing:

1. Wind Bobbin: Wind your bobbin with the desired thread according to your sewing machine's instructions. Ensure the bobbin is wound evenly and not overfilled.
2. Insert Bobbin into Case: Hold the bobbin case with one hand. Place the wound bobbin into the bobbin case. The thread should unwind in the correct direction (usually counter-clockwise when viewed from the top, but refer to your machine's manual).
3. Thread Bobbin Case: Guide the bobbin thread through the tension spring slot on the side of the bobbin case. Pull the thread firmly until it slips under the tension spring and emerges from the small opening.
4. ടെൻഷൻ പരിശോധിക്കുക: Gently pull on the thread. There should be a slight, consistent resistance. If the thread pulls too easily or is too tight, the tension may need adjustment (though typically the bobbin case tension is factory set).
5. Reinstall Bobbin Case: If you removed the bobbin case to insert the bobbin, reinstall it into the machine as described in Section 3.
6. ബോബിൻ ത്രെഡ് കൊണ്ടുവരിക: With the needle threaded, hold the needle thread lightly and turn the handwheel towards you to lower the needle into the needle plate and then bring it back up. This action should catch the bobbin thread, forming a loop. Pull both threads to the back of the machine before starting to sew.

5. പരിപാലനം

Regular maintenance of your bobbin case will ensure smooth operation and extend its lifespan.

• വൃത്തിയാക്കൽ: Periodically remove the bobbin case from the machine. Use a small brush or lint roller to remove any lint, dust, or thread scraps that may accumulate around the tension spring or inside the case. Accumulated debris can affect thread tension and cause stitching problems.
• പരിശോധന: Visually inspect the bobbin case for any signs of damage, such as nicks, burrs, or bends, especially on the edges where the thread passes. Even minor damage can snag thread and lead to poor stitch quality. If damage is found, replacement may be necessary.
