3. সেটআপ এবং ইনস্টলেশন

Before winding thread onto a bobbin, ensure your sewing machine is turned off and disconnected from the power source for safety. Refer to your specific Juki sewing machine's manual for detailed instructions on accessing the bobbin winder mechanism.

3.1. Preparing the Bobbin Winder

1. Locate the bobbin winder spindle on your Juki sewing machine.
2. Take one genuine Juki bobbin from the pack.
3. Carefully place the bobbin onto the winder spindle. Ensure it fits snugly and securely without excessive play. A proper fit is crucial for even thread winding.

Note: Genuine Juki bobbins are designed to fit precisely on the winder spindle, preventing slippage or uneven winding.

4. Operating Instructions (Bobbin Winding)

Once the bobbin is correctly placed on the winder spindle:

1. Thread the bobbin winder according to your sewing machine's specific instructions. This typically involves guiding the thread from the spool pin through tension discs and then around the bobbin.
2. Engage the bobbin winder. This usually involves pushing the winder assembly towards the handwheel or engaging a lever.
3. Turn on the sewing machine and gently press the foot pedal. The bobbin will begin to rotate and wind thread.
4. Monitor the winding process to ensure the thread is distributed evenly across the bobbin.
5. Once the bobbin is full, or when the desired amount of thread is wound, disengage the bobbin winder and cut the thread.
6. Remove the wound bobbin from the spindle.

For visual guidance on bobbin winding, refer to your Juki sewing machine's main instruction manual or official Juki support resources.

• সঞ্চয়স্থান: Store unused bobbins in a clean, dry container to prevent dust accumulation and corrosion.

6. সমস্যা সমাধান

6.1. Bobbin Does Not Fit or Winds Unevenly

If a bobbin does not fit securely on the winder spindle or if thread winds unevenly, verify that you are using a genuine Juki bobbin (Part #229-32909). Non-genuine bobbins may have incorrect dimensions, leading to poor fit and winding issues. Always use bobbins specifically designed for your Juki machine model.

6.2. Thread Breakage During Winding

Ensure the thread path to the bobbin winder is clear and free of obstructions. Check for proper tension settings on the bobbin winder tension disc. Inspect the bobbin for any burrs or sharp edges that could be cutting the thread.
