Needles are sharp and these machines can go very fast. Keep fingers clear of the needle, and when a needle is dull, bent, broken, or breaks your skin place it in the sharps disposal container.
-
To prevent getting tangled in the machine, don't wear loose jewelry or clothing, and tie up long hair.
-
Always turn the power off before changing the needle or servicing the machine in any way.

Use the correct needles and bobbins. Ensure they are installed straight and fully inserted.

The Juki DDL-8700 uses needles in sizes #9 through #18 (Metric sizes 65 to 110) for light to medium-heavy fabrics. The image shown here is specific to the Juki DDL 8700 machine.

The Juki DDL-8700 uses a standard Type L (Class 15 style for industrial) metal bobbin with small holes on the sides, officially designated by Juki part number 229-32909.
-
Bobbin winders on the machines should be used to maintain proper winding tension. Don't wind bobbins by hand.

Follow the threading diagrams for each machine as provided in the manual. The image here shows how to thread the Juki DDL-8700.

Load bobbin into bobbin case and click it into place.

-
Use the dials to adjust stitch length and upper tension according to the manual for the machine you are using.
-
We don't recommend changing the bobbin case tension. If you find that the tension is wrong no matter what you do on the top, turn the screw on the outside of the case in very small increments until when you hold the thread, it falls about an inch after being gently bounced up an inch. The image shown here is specific to the Juki DDL-8700.
