1. On skip-stitch models place the skip-stitch ratio lever in the 1 to 1 position.
2. Turn the handwheel in the proper direction until the point of the needle is directly over the center
(or high point) of the rib.
3. Turn the knob to the left “More” until the rib just barely touches the point of the needle.
4. Make another test run and adjust the knob in accordance with (a) and (b) above.
H. ADJUSTING THE LENGTH OF STITCH
1. It is rarely necessary to change the length of the stitch on U.S. BLIND STITCH machines once
they have been preset at the factory. However, in the event that the need does arise, the simple
procedure outlined below should be followed:
2. Remove the side cover by loosening the attaching screw (item “A” in Figure 1) and observe the
machine from the rear.
3. The numbered disc (item “A” in Figure 5) is called the stitch regulating collar. The position of this
collar with respect to a notch on the rim of the feed eccentric (item “B” in Figure 5) determines the
length of stitch. Before changing the length of the stitch, note the original setting of the notch with
respect to the stitch regulating collar.
4. Loosen the screw (item “C” in Figure 5) which locks the stitch regulating collar in position. Insert
a screwdriver blade in the split on the stitch regulating collar which will be found directly beneath
the locking screw. While holding the screwdriver firmly in position, move the handwheel until the
notch on the rim of the feed eccentric is lined up with the desired number on the stitch regulating
collar. To increase the length of stitch from the original setting, move the notch to a higher number.
To decrease the length of stitch from the original setting, move the notch to a lower number.
5. Before retightening the stitch regulating collar locking screw, turn the handwheel slowly by hand
and observe to insure that no interference has been created between the feed dog and the presser
foot and looper.
6. After the correct adjustment has been established, the stitch regulating collar locking screw
should be retightened. When retightening the screw, however, pull the handwheel to the right and
hold it in that position until the screw is completely tight. This will assist in the proper reseating of
the stitch regulating collar.
