When the feed dial is set to 0, the feed dial gear and idle gear and feed cam alignment marks should match.
ADJUSTMENT

2. Check that the feed dial gear alignment mark and idle gear alignment mark match.
3. Check that the idle gear alignment mark and feed cam alignment mark match.
4. Install with the two screws.
Assembly Points
Tighten the feed bracket assembly screws in the order (C) (D).
Adjustment Points
2. If the feed dial gear alignment mark and idle gear alignment mark do not match, remove the idle gear lock
rating, move the gear meshing to lineup the alignment marks, then reinstall the lock ring.
Be careful about backlash between the feed dial gear and idle gear and the feed cam.
* If the backlash is too small, the feed dial moves sluggishly.
If the backlash is too large, the intended feed is not achieved.
To adjust the backlash, loosen the screw (A), move the idle gear left and right, then after the adjustment is
complete, tighten the screw (A).
