TO REGULATE PRESSURE ON THE MATERIAL
The pressure on the material is regulated by knurled
thumb nut O, Fig. 31. To increase the pressure, tighten
the thumb nut. To reduce the pressure, loosen the
thumb nut.
Heavier pressure is required for leather work than
for sewing cloth or cotton materials. The pressure
should be only heavy enough to enable the feed to
move the work along evenly.

TO TURN A CORNER
Stop the machine with the needle in the work and
turn top of hand wheel over toward you until the
feeding foot rises. Then turn the work as desired,
using the needle as a pivot.
NOTE: If h and wheel is located on front of machine,
turn top of hand wheel over to the right.
TO CHANGE DIRECTION OF THE FEED
While stitching, the work is moved along by the
action of the feeding foot only.
The direction of the stitching can be changed as
desired by turning the foot around by means of the
two handles E, Fig. 32.
Fig. 33. Changing Feed Direction
TO CHANGE THE NEEDLE PLATE
1. Raise the needle bar to its highest position.
2. Loosen screw Q, Fig. 33 and, by lifting upward,
remove needle plate and hinge pin P.
3. When replacing the needle plate, place flat side
of pin P toward screw Q.
4. Tighten screw Q on flat side of pin P.
TO REGULATE THE AUTOMATIC LIFT
OF THE FEEDING FOOT
While the machine is in operation, the feeding foot
rises after it has moved the work forward; then the
foot moves toward the needle and descends again
upon the fabric. It is advisable that the lift of the foot
should be only sufficient to clear the thickest part of
the work.
To adjust the lift, raise the feeding foot by means of
lifter B, Fig. 31. To increase the feeding foot lift, loosen
wing screw N and move the screw toward you. To
reduce the lift, move the screw away from you. When
the desired height of lift is obtained, tighten the wing
screw.
