20.Remove the Belt Cover (part 4, on page 27). Swing the sewing machine so the base is in the operating position, resting on the table. Set the Bobbin Winder to the ‘ON’ Position-see ON Position, below.

21.Make sure the Bobbin Winder is in the ‘ON’ position. Position the Base (Bobbin Winder Base Assembly) (1) so that the Thread Winder Assembly (3) lines up with and just touches the belt. Mark pilot hole locations on the table at the far end of each of the two channels in the Base as indicated in Figure A.

22.Set the Base (1) aside and swing the sewing machine out of the way. Carefully drill straight pilot holes for each of the two locations marked above. Place the base in location and secure using two Wood Screws (26) and Washers (27).

Leave the Screws just loose enough to allow the Base to slide.
