                    Before Using Your Sewing Machine
                    Before using your sewing machine for the first
                    time, place a waste fabric under the presser foot
                    and run the machine with thread for a few
                    minutes. Wipe away any oil which may appear.
                    For Your Safety
                    * While in operation, always keep your eyes on
                      the sewing area. Do not touch any moving
                      parts, such as the thread take-up lever,
                      handwheel or needle.
                    * Always turn off the power switch and unplug
                      from the power supply:
                      - When leaving the machine unattended
                      - When attaching or removing any parts
                      - When cleaning the machine
                    * Do not place anything on the foot control,
                      when not sewing.
                    Polarized plug
                    This appliance has a polarized plug (one blade wider
                    than the other). To reduce the risk of an electric
                    shock, this plug is intended to fit in a polarized outlet
                    only one way. If the plug does not fit in the outlet,
                    reverse the plug. If it still does not fit, contact a
                    qualified electrician to install the proper outlet. Do not
                    modify the plug in any way.

                                       Pull the table away from the machine, as
                                       illustrated, for “free-arm” sewing of cuffs and
                                       sleeves.

        t                              Push the extension table until it snaps into the
    w                                  machine.

                         Aiguille          Raise the needle to its highest position by
                                           turning the handwheel counterclockwise,
                                           toward you, and lowering the presser foot.
                                           Loosen the needle clamp screw q by
    z                x                     turning it counterclockwise. Remove the
                                           needle from the needle clamp w.
                                         x Insert a new needle into the needle clamp
w                                          with the flat side to the rear. When inserting
                                           the needle into the needle clamp w, push it
                                           up as far as it goes. Tighten the needle clamp
                                           screw q firmly by turning it clockwise.
               q                         c To see if the needle is good, place the flat
                                           side of the needle onto something flat (e.g
                                           needle plate or glass).
                                           The gap between the needle and the flat
                                           surface should be consistent. Never use a
                                           bent or blunt needle.
                                           A damaged needle can cause permanent
    c
                                           snags or runs in knits, fine silks and silk-like
                                           fabrics.
                                         * In general, fine thread and needles are used
                                           for sewing thin fabrics, and thicker threads and
                                           needles are used for sewing heavy fabrics.
                                           Always test thread and needle size on a small
                                           piece of fabric which will be used for actual
                                           sewing.
                                         * Use the same thread for needle and bobbin.
                                         * When sewing stretch, very fine fabrics and
                                           synthetics, use a BLUE TIPPED needle. The
                                           blue tipped needle effectively prevents skipped
                                           stitches.
                                         * When sewing very fine fabrics, sew over a piece
                                           of paper to prevent yarn distortion.

                                           (magnified to show detail). If you look at the
                                           top and bottom of a seam, notice that there are
                                3          no gaps. Each stitch is smooth and even.
                                           When adjusting the needle thread tension, the

                                           Results depend on:

             Zigzag Stitch
             For an ideal zigzag stitch, the bobbin thread
             does not show on the right side (Top side) of the
             fabric and needle thread shows slightly on the
             wrong side (Bottom side) of the fabric.
             See the illustrations for correct appearance.
             To match this appearance, adjust the needle
             tension.

              without causing excessive puckering or
              causing bobbin thread to show on the right
              side (Top side) of the fabric.

                 • Starting to sew
                   Raise the presser foot and position the fabric
                   next to a seam guide line on the needle plate
                   (5/8˝ [1.6 cm] is most common). Lower the
                   needle to the point where you want to start.
                   Lower the presser foot and pull the threads
                   toward the back. Depress the foot control.
                   Gently guide the fabric along a seam guide
                   line letting the fabric feed naturally.
                 • Finishing sewing
                   To fasten the ends of a seam, press the
                   reverse stitch control and sew several reverse
                   stitches. Raise the presser foot. Remove the
                   fabric, draw the threads to the back and cut
                   them with the thread cutter. The threads are
                   now the proper length to begin sewing the next
                   seam.
                   CAUTION: Do not place fingers near the
                   presser foot when guiding fabric, or the
                   needle clamp screw may strike and injure
                   your fingers.
                 To Change Sewing Direction
                 Stop the machine and turn the handwheel toward
                 you to bring the needle down into the fabric.
                 Raise the presser foot.
                 Pivot the fabric around the needle to change sew-
                 ing direction as desired. Lower the presser foot
                 and continue sewing.
                 Use the Seam Guides
                 The seam guides on the needle plate are there
                 to help you measure seam width. The numbers
                 on the needle plate indicate the distance
                 between the center needle position and the
                 edge of the fabric. The lines are 1/8˝ (0.3 cm)
                 apart, and are engraved at 3/8˝, 4/8˝, 5/8˝ and
                 6/8˝. The lines in millimeters are 5 mm apart,
                 and are engraved at 10 mm, 15 mm and 20 mm.
