Push the silver thumb lever down toward the
bobbin and the motor will engage (Photo 6).
When the bobbin is full the motor will
automatically shut off.
NOTE: The variable speed should be set
slower for more delicate or stretchy thread
for proper winding. For even winding do not
change speed during bobbin winding.
If necessary to adjust bobbin capacity, tighten the
phillips screw (Photo 6) on the thumb lever stop
spring clockwise for more thread, turn counter-
clockwise for less thread. If bobbin is winding
unevenly, adjust by loosening phillips screw on
pre-tension assembly (Photo 1, #K page 27), and
sliding the assembly left or right until proper fill is
established. Tighten screw.

SERVICE: The bobbin winder shaft is factory lubricated with
synthetic grease, however if it becomes dry or noisy you will
need to lubricate with your machine-hook oil. Oil sparingly
and cover the oil hole with a paper towel. Run for 10 seconds
before winding a new bobbin to avoid getting oil on your
thread (Photo 7).
WARNING: Never leave bobbin winder running unattended.
To reduce the risk of burns, fire, electric shock or injury to
persons, use this machine for its intended use only. Do not
allow this machine to be used as a toy or by unsupervised children.
