FABRIC, THREAD, AND NEEDLE COMBINATIONS

Note

Never use a thread weighted #20 or lower. It may cause machine malfunction.

Memo

The lower the thread number, the thicker the thread; and the higher the needle number, the thicker the 
needle.

Ball point needle

Use the ball point needle when sewing on stretch fabrics or fabrics where skipped stitches easily occur. 
The factory recommended needle is “HG-4BR” (Organ). Schmetz needles “JERSEY BALL POINT” 130/705H SUK 
90/14 may be used as a substitute.

Transparent nylon thread

Use a 90/14 to 100/16 needle, regardless of the fabric or thread.

Make sure you follow the needle, thread, and fabric combinations listed in the table. 
Using the wrong combination, such as heavyweight fabric like denim with a small needle
(65/9-75/11), may bend or break the needle. The wrong combination may also cause the seam
to be uneven, the fabric to pucker, or the machine to skip stitches.
