When placing a new sewing hook on the shaft, have the sewing hook thread guard U at the bottom and the
bobbin case holder V
tumed
to the position shown in Fig. 16, so
that
the hook will clear the feed bar Q.
Place the hook in position on the shaft and turn the bobbin case holder V until the notch W is at the
top,
as
shown in sketch at left above. Replace the bobbin case holder position bracket S, making certain that the finger Y
(see above) enters the notch W at the top
of
the bobbin case holder. Then securely fasten the position finger by
means
of
the
screw
R.
Replace the needle. Time the sewing hook, as instructed on page S. Replace the bobbin case, throat plate and
slide plate.
