Refer to the machine's threading guides for correct bobbin winding. Place the thread spool on the spool pin, guide the thread through the tension discs, and then onto the empty bobbin. Engage the bobbin winder and press the foot pedal or start/stop button to begin winding. The machine will automatically stop when the bobbin is full.

The Bernette B77 features a convenient drop-in bobbin system. Open the bobbin cover plate, insert the wound bobbin with the thread unwinding in the correct direction (usually counter-clockwise), and guide the thread through the bobbin tension slot. Replace the cover plate.

4. Vzdrževanje
4.1 Čiščenje
Regularly clean the bobbin area, feed dogs, and tension discs to remove lint and thread buildup. Use a small brush or lint remover. Always disconnect the machine from the power supply before cleaning.
4.2 Mazanje
Consult your full user manual for specific oiling points and frequency. Use only high-quality sewing machine oil. Over-oiling can attract more lint and cause issues.
4.3 Zamenjava igle
Replace needles frequently, especially when working with different fabric types or if the needle becomes dull or bent. A dull needle can cause skipped stitches, fabric damage, or needle breakage. Always use the correct needle type and size for your fabric.
5. Odpravljanje težav
5.1 Preskočeni šivi
If the machine is skipping stitches, check the needle. Ensure it is inserted correctly, is not bent, and is the appropriate type and size for your fabric. Re-thread the machine, both top thread and bobbin, ensuring proper tension.
5.2 Pretrg navoja
Thread breakage can be caused by incorrect threading, improper tension, a damaged needle, or poor quality thread. Verify the threading path, adjust tension, replace the needle, and ensure you are using good quality all-purpose sewing thread.
5.3 Fabric Jamming
Fabric jamming often occurs if the presser foot is not lowered before sewing, or if the wrong presser foot is used. Ensure the presser foot is down and matches your sewing task. Do not force fabric through the machine.
