NEEDLE THREADER
USING THE NEEDLE THREADER
There are a wide variety of different needles and sewing machine threads available. The right ones should be
selected in accordance with the sewing conditions. The accessory needle threader is designed to make threading of
needles easier, but it cannot handle every single circumstance of use (combinations of needle and thread) that may
occur. It can be used with some combinations but not with others, and if it can be used, the pattern may not be sewn
correctly due to the particular sewing conditions. Do not use the needle threader without gaining a thorough
understanding of how to use it, otherwise the needle threader may be damaged or needle threading may not be
possible. Be sure to read and understand the following so that you can handle customer complaints.
NOTE:
1. Needle threader accepts only circled needle and thread combinations.
2. Combinations marked with a * are not recommended since they might lead to the breakage of needle threader
imperfect performance.
3. Lower the presser foot when you use needle threader.
4. Nylon transparent thread is applicable in needle #14-16.
5. Do not turn the balance wheel when using needle threader.
6. Do not lower the needle threader lever while the machine is running. If it is lowered, the needle threader may
be broken, rendering it unusable. Besides this, it may cause the needle to break, which could result in injury.
7.
If a #9 needle is used, the variation in needle precision may result in the needle being slightly difficult to thread.
8. Needle should be located above needle plate by more than 8 mm for threading.
9. Needle threader does not work when you use the side-cutter.
Thread the needle before attaching the side cutter.
10. When doing embroidery, use a #11 needle.
Use special Brother #50 embroidery thread and #50-#80 silk thread
for the embroidery thread.
