Changing the needle
CAUTION:
Turn OFF the power switch before changing the needle.
Turn OFF the power switch. Raise the needle to its highest position by turning the handwheel counterclockwise, and lower the presser foot. 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 goes. Tighten the needle clamp screw 
firmly by turning it clockwise.
To see if the needle is good, place the flat side of the needle onto something flat (stitch 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.
Needle clamp screw Needle clamp
Fabric and Needle Chart
Use a needle size of 11/75 or 14/90 for general sewing work.
A fine thread and needle should be used for sewing lightweight fabrics, so the fabric will not be marred.
Heavy fabric requires a needle large enough to pierce the fabric without the needle thread fraying.
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.
PLEASE NOTE:
Three no. 14/90 needles are included in the needle set. For optimal sewing results, it is recommend using Organ needles.
PLEASE NOTE:
Use a blue shank needle (available separately) when sewing flexible fabrics, very fine fabrics and synthetic fabrics. The blue shank needle effectively prevents skipped stitches.
