Needle Thread Tension - Janome MO200 Service Manual

NEEDLE THREAD TENSION

The standard tension should be 80 to 95 grams when the tension dial is set at "A" (auto), measured with
a #50 white polyester thread being pulled at approximately 110 mm/sec.
If the tension is outside the standard range, adjust as follows:
ADJUSTMENT:
1. Set the thread tension dial to "A" and check the thread tension.
2. Remove the face cover (see page 4).
3. If the tension is outside the standard range, turn the dial to find a position where the correct tension is
obtained.
4. Insert a screwdriver into the slit on the shaft and push it until the tension dial is disengaged from the shaft.
5. While holding the shaft in place with the screwdriver, turn the dial back to position "A" and engage it
with the shaft.
6. Remove the screwdriver.
7. Check the thread tension to confirm that it is correct, then install the face cover.
Pull the thread at a speed of approx. 110 mm/sec.
