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, and lower the presser
foot.
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 flat
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 firmly by turning it
clockwise.

Flat side
To see if the needle is in good condition, place the flat
side of the needle onto something flat (needle plate, glass
etc.). 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 snags or runs
in knits, fine silks and silk-like fabrics.

Fabric and Needle Chart
• For general sewing, use needle size 11/75 or 14/90.
• A fine 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.
• When sewing stretch fabrics, very fine fabrics and
synthetics, use a blue tip needle. The blue tip needle
effectively prevents skipped stitches.
NOTE:
1 x blue tip needles (#11/75), 2 x #11/75 needles and 2
x #14/90 needles are included in the needle case (Part
No. 540401026).
