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 turned 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 5. Re-
place the bobbin case, throat plate and slide plate.
TO REPLACE OIL FILTER 143042
While the sewing hook is off the shaft, it is advisable to replace the oil
filter 143042, Fig. 15 in the end of the hook shaft. Unscrew the filter from
the center of the shaft at X, Fig. 15 and replace with a complete new filter
143042.
