The thread may not pick up from the bottom on the Luby JG-1602 due to the following possible causes:

1. Upper Thread Not Threaded Correctly – Ensure the upper thread is correctly threaded as per the instructions.
2. Bobbin Thread Not Installed Properly – Check if the bobbin thread is threaded correctly.
3. Incorrect Needle Position – Raise the needle to its highest position using the hand wheel.
4. Bent or Damaged Needle – Replace the needle if it is bent or damaged.
5. Dust Buildup in the Bobbin Case – Clean the bobbin case to remove any dust or lint.

Following the correct threading and maintenance steps should resolve the issue.
