   The tension on the thread is automatic and sel-
dom requires changing. When the needle is at its           INSTRUCTIONS
 highest point, the nipper lever (D, Fig. 2, page 2)                         FOR USING

thread for the next stitch. The tension is regulated                                          No. 20by the thumb nut (C, Fig. 2) at the front of the
tension discs. To increase the tension, turn this
thumb nut over to the right. To decrease the ten-
sion, turn the thumb nut over to the left.

        To Use the Cloth Guide

  To ensure accurate guiding of the work when
sewing close to the edge of the goods, the cloth
guide (P, Fig. 2, page 2) should be used. Fasten
the cloth guide to the cloth plate of the machine
by means of the clamping thumb screw (0, Fig. 2),
inserting the thumb screw into the screw hole in the
cloth plate. The cloth guide can be adjusted to
bring the edge of the goods as close to the line of
stitching as desired. If desired, the cloth guide
can be removed from the machine.

          To Oil the Machine
  The machine should be oiled occasionally with
the sewing machine oil especially prepared by the
Singer Sewing Machine Company. This oil can be
purchased from any Singer shop or Singer sales-
man. Apply one drop of oil at each of the places
where a part of the machine moves against another          THE SINGER MANUFACTURING CO.
