TO ADJUST THE CLEARANCE BETWEEN
NEEDLE AND UPPER LOOPER
When the upper looper (A) meets with needle, clearance (C) should be:
* 0.1 to 0.15mm at the needle on the left.
* 0.2 to 0.05 mm at the needle on the right.
To adjust:
1. Turn the balance wheel toward you with your hand to bring the needle just behind the upper
looper (A) in downward travel.
2. Loosen the setscrew (B), and adjust the clearance (C) between the both needles and upper
looper (A).
3. Tighten the setscrew (B).
4. Check the clearance between the loopers.
