REFERENCE - OVERLOCKER NEEDLES
BERNINA Overlocker Needles
Along with thread, needles are very important to stitch formation. Many mechanical problems and damage to fabrics can be
traced to a bent, damaged, or incorrect size or type needle.
When selecting the correct needle, consider the following:
• Recommended needle system for L 890 – ELX705. These needle are a flat shank needle. A pack of these needles is included
with the overlocker.
• Recommended sizes for your overlocker are 70/11, 80/12 and 90/14. Larger needles
can interfere with looper movement and cause damage; smaller needles may not
form the stitches correctly.
• Needle point – assures proper stitch formation; avoids fabric damage
• You may use needle systems other than those recommended to accommodate the
usage of certain specialty needles (stretch, Microtex, etc), but keep in mind that
adjustments to tensions may be required for a proper stitch formation.
Need to Know
• Always make sure needles are fully inserted as high as possible, with the flat side to the back. The
left needle will appear to be slightly higher than the right needle.
• Do not pull or push fabric while sewing. This can result in needle breakage or damage.
• Do not use bent or damaged needles.
• The needle is the most inexpensive part in your sewing machine, but it is crucial for getting good results and keeping your
machine running well.
• The selected thread should fit in the groove on the front of the needle. If it isn’t protected by the groove, a needle with a
larger groove should be used.
Tip:
If one needle breaks, it is a good habit to change both needles. Keeping the needle size and type the same results in a
better formed stitch.
