Lubricating
For machines with the
metal CB-hook system,
lightly oil (1-2 drops) the
hook race. After replacing
the bobbin case and bob-
bin, sew off the machine
on scrap fabric to prevent
oil from getting on your
work. Machine should be
oiled each time it is clea-
ned.
Important!
Never use oil, alcohol or
solvents of any kind on any
part of the machine!
