6. Timing of Shuttle Hook in relation to Needle Bar

position and stitch width knob at "0.")

Remove the 2 Spring Screws which hold upper guard ring to
lower guard ring.
Do not remove the two screws which hold the Shuttle Beak
to the upper guard ring.

Turn flywheel slowly toward you until the opening in the
Shuttle Hook faces towards the back of the machine.
With a finger, turn the Lower Guard Ring inside of shuttle
hook until the straight edge of the lower guard ring is aligned
with the edge of the shuttle hook opening.
Pull out lower guard ring through the opening in the shuttle
hook.
Loosen slightly the three screws at the bottom of the shuttle
hook until the shuttle hook can be turned with slight friction.
