TO ADJUST THE NEEDLE AND THE
LOWER LOOPER TIMING
Correct Setting:
When the needle comes up 2.8 to 3.2 mm (7/64 to 1/8”) from its lowest position, the tip of the lower looper
comes just left of the needle on the right.
To adjust:
1. Remove the presser foot, needle plate and left-side needle.
2. Replace right-side needle with a #11 one.
3. Turn the handwheel toward you to get the lowest needle position.
4. Set the two gauges (787-G02, 787-G03), as in (Fig. 1) and tighten bolt B.
* This time, there should be no clearance between the gauges and the needle bar lower bushing.
5. Remove plate gauge (787-G03). Then turn handwheel toward you until it touches the needle bar lower
bushing, as in (Fig.2)
6. In this condition, loosen the hexagon bolt C just enough to move the lower adjust the lower looper base (2).
Adjust the lower looper position in order to meet the tip of lower looper with left-side of needle (#11).
Tighten hexagon bolt C, as in (Fig.3) and (Fig.4).
7. Remove the gauge (787-G02).
* Check the clearance between the needle and lower looper.
* Check the clearance between the loopers.
8. Replace the right side needle with a #14 one.
9. Attach the needle, needle plate and presser foot.
* Be careful not to tighten bolt B too much.
