Change the needle often. As a general rule,
needles should be changed every 6-8 hours of
actual stitching time.
Always use a straight needle with a sharp point and make sure
the point is not bent or damaged (A).
A damaged needle (B) can cause skipped stitches, breakage or
snapping of the thread. It can also damage the needle plate.
Do not use asymmetrical twin needles (C), they can damage
your sewing machine.

Change the Needle
Note: Before you begin changing the needle, it can be helpful
to place a small piece of paper or fabric underneath the needle
area, over the hole in the needle plate, so that the needle
doesn't accidentally fall down into the machine.
1. Loosen the needle clamp screw. If it feels tight, use the
screwdriver from your accessories to aid with loosening
the screw.
2. Remove the needle.
3. Push the new needle upwards into the needle clamp with
the flat side away from you.
4. When the needle will go up no further, tighten the screw
securely.
