Common Reasons to Change the Needle
• The needle breaks or is bent.
• The thread will consistently fray - this usually means there is a bur
on the needle causing it to fray a part of the thread.
• The needle is dull.
• Sewing conditions change, such as a change in fabric.
Choosing a Needle
Your machine utilizes DBxK5 needles. Among other things, this means that
they are industrial needles with larger eyes.
Needle Sizes
Needles come in a variety of sizes, and most are marked with two numbers.
For example, you will nd 75/11 needles. The rst number is metric and is
the diameter of the needle blade. It is measured in hundredths of a millime-
ter. A 75/11 needle has a blade that is 0.75mm in diameter.
Standard sewing conditions will utilize needle sizes ranging from 65/9 to
80/12 needles.
Smaller needles work well for ner materials, thinner threads, and delicate
detail work.
Larger needles work well for tougher and more abrasive materials. As the
holes made by the needle are larger, sewing creates less friction on the
threads and helps prevent thread breaks.
