Changing Needles 
(Fig. 1)
Raise the needle by turning the handwheel toward 
you and lower the presser foot.
z  Loosen the needle clamp screw by turning it 
counterclockwise.
    Remove the needle from the clamp.
x  Insert the new needle into the clamp with the 
flat side away from you.
    When inserting the needle into the clamp, push 
it up as far as it will go and tighten the clamp 
screw firmly with the screwdriver.
To check the needle 
(Fig. 2)
Place the flat side of the needle on something flat 
(needle plate, glass etc.). The clearance between the 
needle and flat surface should be consistent. Never 
use a bent or blunt needle.

3 x #14/90 needles are included in the envelope. 
(Part No. 639804000).
NOTE:
When sewing stretch fabrics, very fine fabrics 
and synthetics, use a blue tip needle (Part 
No. 990311000, sold separately). The blue tip 
needle effectively prevents skipped stitches.
