Adjusting the Needle Thread Tension

The ideal straight stitch has threads locked between two
layers of fabric, as illustrated (magnied to show detail).
If you look at the top and bottom of the seam, notice that
the stitches are evenly balanced.

When adjusting the needle thread tension, the higher the

- number of fabric layers
- type of stitch

Zigzag stitch balanced tension
For an ideal zigzag stitch, the bobbin thread does not
show on the right side (top side) of the fabric, and the
needle thread shows slightly on the wrong side (bottom
side) of the fabric.
See the illustrations for the correct appearance.
To match this appearance, adjust the needle tension as
necessary.
Balanced tension
Minimize the amount of needle thread visible on the
wrong side (bottom side) of the fabric without causing
excessive puckering, or causing the bobbin thread to
show on the right side (top side) of the fabric.
Results vary with fabric, thread and sewing conditions.

Dropping or Raising the Feed Dog
The drop feed lever is located lower part of the free arm
bed on the front of the machine.
To drop the feed dog, push the lever in the direction of
the arrow q.
To raise the feed dog, push the lever in the direction
of the arrow w, as illustrated, and turn the handwheel
toward you.
The feed dog must be up for normal sewing.
Changing the Needle
CAUTION:
Turn OFF the power switch before changing the
needle.
Raise the needle to its highest position by turning the
handwheel counterclockwise.
A loose needle or a loose screw may cause machine
malfunction or needle to break.
Loosen the needle clamp screw by turning it
counterclockwise. Remove the needle from the needle
clamp.
Insert a new needle into the needle clamp with the at
side to the rear. When inserting the needle into the
needle clamp, push it up as far as it will go.
Tighten the needle clamp screw rmly by turning it
clockwise.
q Needle clamp screw
w Flat side
e
To see if the needle is in good condition, place the at
side of the needle onto something at (needle plate, glass
etc.). The gap between the needle and the at surface
should be consistent. Never use a bent or blunt needle.
A damaged needle can cause permanent snags or runs
in knits, ne silks and silk-like fabrics.

Fabric, Thread and Needle Chart
• For general sewing, use needle size 11/75 or 14/90.
• A ne thread and needle should be used for sewing
lightweight fabrics, so the fabric will not be marred.
• Heavy fabrics require a needle large enough to pierce
the fabric without fraying the needle thread.
• Always test the needle size on a small scrap of the
fabric that will be used for actual sewing.
• In general, use the same thread for the needle and
bobbin.
NOTE:
When sewing stretch fabrics, very ne fabrics and
synthetics, use a blue tip needle (Part No. 990311000,
sold separately). The blue tip needle effectively
prevents skipped stitches.
