TO WIND THE BOBBIN
See Fig. 13.
Fasten bobbin winder to table with its driving pulley in front of
the machine belt, as shown below, so that pulley will move away from
belt when sufficient thread has been wound upon the bobbin.
PLACE BOBBIN
ON SPINDLE
Fig. 13. Winding the Bobbin
Place bobbin on spindle, pushing it on as far as it will go and pass
thread through threading points, as shown above.
Wind end of thread around the bobbin a few times. Press down
on thumb latch, pushing driving pulley over against belt, as shown in
Fig. 13. Start machine.
Bobbin winder will stop automatically, when the amount of thread
for which it is regulated is wound upon the bobbin. For more thread
on bobbin, turn screw A inward; for less thread on bobbin, turn screw
A outward.
When winding a bobbin with fine thread, a light tension should
be used. Adjust the knurled nut X, Fig. 13, to regulate the tension.
If thread winds unevenly on bobbin, loosen screw B and move
tension bracket C to the left or right, as required. Tighten screw B.
Bobbins can be wound while the machine is stitching.
NOTE: Occasionally apply a few drops of oil to the oil well, shown
in Fig. 13, on top of the bobbin winder frame.
