ADJUSTMENT FOR CORRECTING CLEARANCE
BETWEEN NEEDLE AND SHUTTLE HOOK }
For perfect stitching the needle must be as near the hook as
possible without touching it and skipped stitches are often caused
by incorrect clearance between needle and hook, Using a perfectly
straight needle, test in the following manner:
1, Remove bobbin case and shuttle race cover.
2. Turn hand wheel until needle is directly over point of hook.
3. Hold hook in place and touch needle with a screwdriver. There
should be a slight movement of needle. If not, set zigzag
width lever at 5 with stopper and loosen vertical shaft driving
rod set screw (#151) slightly. Tilt bed up and tap shuttle
race down lightly with mallet or the like until correct clearance
is obtained.
4, If there is too much movement of needle or too great a distance
between needle and hook, first pull shuttle race up until needle
touches tip of hook and then tap shuttle race down lightly until
correct clearance is obtained.
