The feeding of the machine is done automatically. Be sure to guide the material gently with both your hands. Do not push or pull to avoid break ing of the needle.
Taking the hook a piece for cleaning To clean the hook it is necessary to tip the machine back, then remove the upper case and take off the hook bow by unscrewing the three screws S 1, S 2, and S 3. Then, by turning the balance wheel, bring the hook in correlation with the under bobbin case to the effect that the lower edge of screw hole S 1 and the lower edge of shoulder D are in alignment (fig. 9).
The feller When felling, the two pieces of cloth should be laid one upon the other, with the edge of the under piece about 1/6 inch further to the right thon the upper piece. Then guide the two pieces into the feller in the some woy as described with the hemmer, by which the edge of the under piece is folded and sewn on the upper piece. Now open the two pieces of cloth as shown in fig. 12, flatten the seam somewhat and guide the edge, which has been formed, again through the feller in order to fell it.

The Treadle Stand I I Fig. 16 with ball-bearing pitman requires but little attendance. It will be sufficient to apply a drop of oil now and then to the crank points a and b, to the treadle stud c and the treadle bearings d (fig. 18). The ball-bearing of the pit man is filled at the factory with consistent grease, thus render ing lubrication unnecessary for a long time.
