Thread/decorative threads
Sewing and special overlock threads are manufactured in a wide variety of types, weights and combination of fibres. It
is worth investing in good quality threads for perfect sewing results. Decorative threads specially made for overlockers
(available on cones) are also becoming widely available. We recommend following the basic guidelines when using
special threads on your overlocker:
- Purchase threads on cones or spools which are produced exclusively for overlocking.
- When using normal spools, use the spool caps (in accessory bag).
- Only use decorative threads in the loopers. The thread must move easily and without resistance through the thread
guides and looper eyes.
- The thicker the thread, the longer the stitch length (3-4).
- The thicker the thread, the looser the tensions
- Sew slowly when using decorative threads. Pull the thread chain gently to the rear when starting to sew.
Always test sew decorative threads before starting to sew your work.

Needle and thread
The needle size used depends on the thread. The needles should be in accordance with thread used. When sewing,
the thread is fed through the long groove in the needle. If the needle is too fine, the thread does not fit into the groove
and stitches will be skipped. Use needles No. 70 - 90.
* It is recommended to use JL×2 needle, especially when sewing thick materials, over-lapped section, etc, with over-
lock machine.
