Install the new bump knob by aligning it with the spool and pressing it into place. Reattach the spool cover, ensuring it snaps securely.
This issue can occur if the bump knob is worn out or incorrectly installed. Ensure the bump knob is in good condition and replace it if necessary. Additionally, check the spool for tangles or incorrect winding, as a tangled line can prevent proper feeding.
