5. Adjusting clearance between Needle and Shuttle Hook
When clearance between needle and point of shuttle hook is correct, the needle must just clear or barely touch
the point of the shuttle hook.
If this is not the case, proceed as follows:
Remove needle, presser foot and needle plate.
Lower presser foot lever to open front cover (thread take‐up lever must be in a raised position).
Stitch width knob at "0."
Set Centering Dial at Center Position.
Install a straight size 100/16 Needle.
Turn flywheel slowly toward you until point of
Shuttle Hook is exactly behind the center of the
needle.
Slightly loosen the Set Screw in the Cradle
Support.
Insert screw driver into Positioning Bolt and
turn until needle just clears, or barely touches,
the point of the shuttle hook.
Tighten Set Screw after this adjustment.
Close front cover, replace needle, needle plate and presser foot.
