To Oil And Clean The Machine 2 - Pfaff 130-6 Instruction Book

Thread breaking may be caused by;
1. Any of the three reasons mentioned above.
2. Tension too tight.
3. Using bad or knotty thread.
Bad stitches may be caused as a result of;
1. Tensions being too loose or too tight. Both tensions
should be equal.
2. Using needles and threads that do not conform to
the thickness of the fabric. Top and bottom thread
should be the same.
3. Fluff having accumulated between the upper tension
discs, or underneath the tension spring of the bobbin
case.
Heavy working of the machine may be caused by:
1. The motor belt having become too loose after con-
stant use, therefore, not pulling properly. In that
case, the motor bracket has to be adjusted.
2. The motor belt being too tight. Do not over-tighten
it.
3. The shuttle race being obstructed by fluff, which
must be removed.
4. The machine having become clogged. Note the fol-
lowing instructions for proper oiling and cleaning.
II. To oil and clean the machine
Apply rust-proof grease
on all nickel-plated and
polished parts. This done, all greased parts should be
cleaned with a clean rag. Then, apply a little PFAFF-Sew-
ing Machine Oil at the oiling points marked with arrows
in Figures 1, 2, and 3.
