Mechanical Adjustment

MODEL: AirThread 2000D

To adjust the pre-tension

Use a standard thread #50 to check the tension of the looper pre-tension.
Standard tension:
Lower looper pre-tension setting slider set to “STD.”: 1 gf or less.
Lower looper pre-tension setting slider set to “TIGHT”: 45-55 gf.

To check:
1. Open the looper cover and remove the belt cover.
2. Check the tension of the lower looper pre-tension with

the standard thread.

3. If the thread tension is not correct, adjust the tension

by inserting a screwdriver in the slit of the thread
tension shaft and turning it.

⇨

If the tension is too tight, turn the thread tension

shaft counterclockwise.

⇨

If the tension is too loose, turn the thread tension

shaft clockwise.

4. Check the thread tension again. Repeat the procedure

of step 3 until the thread tension becomes correct.

5. Attach the belt cover and close the looper cover.
