OPERATING INSTRUCTION
Use HA × 1SP, HA × 1(130/ 705H) Needles.
Synthetic threads are recommended for ordinary overlocking. Polyester thread, for example, is very
useful for different types of fabric.
NOTE :
Keep in mind that the lower and upper loopers will use about twice the amount of thread as the needles.
When purchasing thread for sewing, therefore, especially if it is an unusual colour, you should buy
sufficient for your requirements.

NOTE:
The above settings of tension and overedge cutting width dial are for general guidance. A
little fine tuning will improve your stitching in many cases. Following advice helps you.
1. Turn overedge cutting width dial. (See page 10)
2. Adjust needle tensions when you sew thin or thick material.
3. Reduce the tension when you use thick thread.
4. Incorrect tension setting causes stitch skipping. Adjust the tension setting.
5. Tension setting will have problem when needle setting is incorrect.
Try test-sewing with a piece of fabric you are going to use and find the best settings.
