Needles must be in perfect condition. (2) Problems can occur with:

  • A. Bent needles
  • B. Blunt needles
  • C. Damaged points

Threading the upper thread

This is a simple operation but it is important to carry out correctly as by not doing so several sewing problems could result.

  • Start by raising the needle to its highest point (1), and also raise the presser foot to release the tension discs. (2)
    Note: For safety, it is strongly suggested you turn off the power before threading.

  • Lift up the spool pin. Place the spool of thread on the holder with the thread coming off the spool as shown. For small thread spools, place small side of the spool holder next to spool. (3)

  • Draw thread from sp0ol through the upper thread guide. (4)

  • Guide thread around thread guide (5) pulling the thread through the pre-tension spring as illustrated.

  • Thread tension module by leading thread down right channel and up let channel (6). During this process, it is helpful to hold the thread between the sp0ol and the thread guide (4).

  • At the top of this movement pass the thread from right to left through the slotted eye of the take-up lever and then
    downwards again. (7)

  • Pass thread behind the flat, horizontal thread guide. (8)

  • Now take thread behind the thin wire needle clamp guide and then down to the needle which should be threaded from front to back. Pull about 6-8 inches of thread to the rear beyond the needle eye. (9)

  • Release lever (A).
  • Pull the thread through the needle’s eye.
    Attention:
    Turn the power switch to off (‘o”)!

Thread tension

Upper thread tension

Basic thread tension setting: “4”
To increase the tension, turn the dial to the next number up. To
reduce the tension, turn the dial to the next number down.

  • A. Normal thread tension for straight stitch sewing
  • B. Thread tension too loose for straight stitch sewing. Turn the dial to a higher number.
  • C. Thread tension too tight for straight stitch sewing. Turn dial to a lower number.
  • D. Normal thread tension for zig-zag and decorative sewing9.
  • Correct thread tension is when a small amount of the upper thread appears on the bottom side of the fabric.

Lower thread tension
To test the bobbin thread tension, remove the bobbin case and bobbin and hold it by suspending it by the thread. Jerk it once or twice. It the tension is correct, the thread will unwind by about an inch or twO. If the tension is to0 tight, it does not unwind at all. If the tension is too loose, t wil drop too much. 1o adjust, turn the small screw on the side of the bobbin case.

Please note:

  • Proper setting of tension is important to good sewing.
  • There is no single tension setting appropriate for all stitch Functions, thread or fabric.
  • A balanced tension (identical stitches both top and bottom) is usually only desirable for straight stitch construction sewing. 90% of all sewing will be between “3” and “5”.
  • For zig zag and decorative sewing stitch functions, thread tension should generally be les than for straight stitch sewing.
  • For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric.

Raising the bobbin thread
Hold the upper thread with the left hand. Turn the handwheel (1) towards you (counterclockwise) lowering, then raising the needle.
Gently pull on the upper thread to bring the bobbin thread up through the needle plate hole (2). Lay both threads to the back under the presser top. (3)

Reverse sewing
To secure the beginning and the end of a seam, press down the reverse sewing lever (A). Sew a few reverse stitches.
Release the lever and the machine will sew forwards again. 1)

Removing the work
Turn the handwheel counterclockwise to bring the thread take-up the lever to its highest position, raise the presser foot and remove work behind the needle and presser foot. (2)

Cutting the thread
Pull the threads behind the presser foot. Guide the threads to the side of the face plate and into thread cutter (B). Pull threads down to cut. (3)

The evenfeed foot accessory is optional. It is not included with this machine. Always try to sew first without the evenfeed foot accessory which should be used only when necessary.
It is easier to guide the fabric and you have a better view of the seam when using the standard, regular foot on your machine. Your sewing machine offers excellent stitch quality on a wide range of fabrics from delicate chiffons to multiple layers of denim.
The evenfeed Foot accessory equalizes the feeding of the upper and lower layers of fabric and improves the matching of plaids, stripes and patterns. It also helps to prevent uneven feeding of very difficult fabrics.
