Assembly
1. Rotate your hook assembly so that the positioning guide is at the highest point during
rotation.
2. Attach your hook holder to your sewing machine with a M5 X 10 FHCS (don’t tighten
the screw during this step) with the hook holder’s nger in the middle of the hook
assembly’s positioning guide.
3. Slide your hook holder away from the hook hssembly so there is about a 0.75mm gap
(it’s hard to measure so just make it as big of a gap as possible with the hook holder
still in the positioning guide) between the hook holder and the hook assembly, and
tighten the M5 X 10 FHCS.

Assembly
1. Remove needle plate.
2. Loosen all three hook assembly set screws with a M2 allen wrench by inserting the wrench
into the machines timing hole cut out when each set screw aligns with the hole.
3. Rotate the handwheel clockwise from the front of the machine so needle is raising out of
the hook assembly.
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 handwheel
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.
