8. Adjusting needle clearance using Double Needle Clamp
If the clearance between the two gauges No. 607801 or needles and point of shuttle hook is correct, the point of
the shuttle hook should just clear or barely touch each of the two gauges or needles. If the above requirement is
not met, adjust as follows:
Remove presser foot and needle plate.
Remove single needle clamp and attach double needle clamp in its place.
Insert two needle clearance gauges No. 607801 or two needles 100/16 in double needle clamp.
Lower the 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.
Turn flywheel slowly towards you until point of shuttle hook is just opposite the first needle gauge. Check
clearance between point of shuttle hook and gauge.
Turn flywheel slowly towards you until point of shuttle hook is just opposite the second gauge. Check clearance
between point of shuttle hook and gauge.
If clearances are not equal for both gauges,
proceed as follows:
Loosen screw in needle bar link pin just
slightly so that the needle bar is still held in
position by friction (to prevent dropping of
the needle bar), then turn needle bar
clockwise or counterclockwise (see arrows) as
required until clearances at both gauges are
equal.
Tighten screw in needle bar link pin after this
adjustment.
Remove gauges and double needle clamp. Close front cover. Replace single needle clamp, needle, needle plate
and presser foot.
