    • When adjusting the bobbin case, be sure to remove the bobbin from the bobbin case.
    • DO NOT adjust the position of the Phillips (+) screw on the bobbin case as this may result in damage to the bobbin case, rendering it unusable.
    • If the slotted-head screw (-) is difficult to turn, do not use force.
      Turning the screw too much or providing force in either (rotational) direction may cause damage to the bobbin case.
      Should damage occur, the bobbin case may not maintain proper tension.
