4. Bring the needle so it rests on the top of timing spacer, so the groove in the needle aligns in the
middle of the hook on the hook assembly. The needle should be as close as possible to the hook
assembly without touching, roughly between 0.02mm and 0.075mm.
5. Tighten set screw, make sure needle doesn’t hit hook by watching to see if the needle bends during
rotation and there is no clicking noise. Rotate machine using the hand wheel a full rotation to ensure
the needle doesn’t hit anywhere during rotation. If needle hits the hook assembly anywhere during
rotation adjust needle height up or down off center from hook in 0.25mm increments as appropriate
to clear the collision.
6. Tighten the two remaining set screws and reattach the needle plate.
