Frequently Asked Questions - MC690 JATA

How to thread the needle on the Jata MC690?

Follow the path shown on the machine: top thread guide, tension disc, thread take-up lever, then pass the thread through the needle eye from front to back. Lower the presser foot before sewing.

Why does the needle thread break?

Possible causes: incorrectly threaded thread, tension too high, bent or incorrectly installed needle, unsuitable thread. Check threading (page 17), tension (page 21), and needle condition (page 9).

How to wind the bobbin?

Place the bobbin on the winder, pass the thread around the tension disc, push the winder to the right and press the pedal. It stops automatically when the bobbin is full (page 13).

What to do if the needle breaks?

Use a straight, sharp needle suited to the fabric. Tighten the fixing screw. Do not pull the fabric while sewing. See page 9 for needle selection.

How to clean the machine?

Always unplug the machine. Remove the needle and presser foot, then the needle plate. Brush the feed dog teeth and clean the shuttle race with a soft cloth (page 31).

Why does the stitching form loops?

The needle thread tension is too low or the bobbin tension is incorrect. Adjust the upper thread tension dial and ensure the bobbin thread is correctly inserted (page 21).

How to make a buttonhole?

Use the sliding buttonhole foot. Select the stitch positions in order: forward knit, left zigzag, backward knit, right zigzag. Follow the marking on the fabric (page 29).

What to do if the fabric does not advance?

Clean the feed dogs as they may be clogged with lint. See page 31 for cleaning procedure.

How to replace the bulb?

Unplug the machine. Remove the screw of the front cover, push the bulb upward and turn it counterclockwise to remove. Replace with a 15 W bulb of the same type (page 33).

The machine does not start, what to check?

Ensure the machine is plugged in and the switch is set to 'I'. Check that no thread is blocking the internal mechanism. If the problem persists, consult an authorized repairer (pages 5 and 31).
