Bobbin Winder Maintenance

When the bobbin winder is subjected to heavy or
continuous operation, you may need to lubricate
the bobbin winder shaft. Apply one drop of
sewing machine oil to the bobbin winder shaft as
shown in Figure 3-31. Rotate the bobbin winder
shaft by hand until the shaft moves smoothly and
freely.
