Timing The Machine
Parts Needed:
1. 2mm Allen Wrench
2. Timing Spacer
1.
Loosen all three hook assembly set screws with a M2 allen wrench by inserting the wrench into
the machines timing hole when each set screw aligns with the hole.
2.
Rotate the handwheel clockwise from the front of the machine so needle is raising out of the hook
assembly.
3.
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 as-
sembly without touching, roughly between 0.02mm and 0.075mm.
4.
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 ap
-
propriate to clear the collision.
5.
Tighten the two remaining set screws.
Note:
Only time the sewing machine if replacing hook assembly or machine comes out of timing.
