JUKI DDL-8700 FAQs

What kind of needles do you use in the DDL-8700?

The needles with your JUKI are the Organ DBx1, available on our website. This machine uses size 16×257, size 8 through 20 or 16×97. The 8700 can also use standard needles, sizes 9 through 21, either universal or fabric-specific needles such as knit.

Where does the machine oil go?

A pan directly underneath the machine supplies oil to the machine with a cotton wick. Lift the machine up and over to access the oil tank while on the table. You must keep the machine’s oil level consistently at the «high» mark, either by adding more oil or draining it and refilling it as needed. If the oil pump can’t get the oil into the machine, it can cause serious problems later.

What kind of oil does this machine require?

You need a specific type to keep this machine running, like motor oil in your car. The DDL-8700 requires JUKI New Defrix Oil No.1, which is equivalent to ISO VG7.

What size table can I get with this machine?

Our table is 22"w x 47"l, with legs. It includes a knee pedal and foot pedal, as well as a left-hand drawer for accessories.

Does the DDL 8700 make buttonholes?

No. The 8700 only does straight stitching, with a horizontal bar on the right side for a reverse stitch.

THE ADVANTAGES OF A SERVO MOTOR:

• They use up to 90% less power than clutch motors
• They are 1/3 lighter than clutch motors
• With a flick of the switch, you can reverse motor rotation
• No parts to wear out or adjust.
• No matter how hard you press the foot pedal configured speed remains the same

Because of the Servo motor speed control, most users find the machine easier to use. Both beginning and seasoned sewers find this feature helpful when stitching projects that don't demand high-speed stitching.
