TENSIONS
The needle and bobbin threads should be locked in the center of the
thickness of the material, thus:
Fig. 15. Perfect Stitch
If the tension on the needle thread is too tight, or if that on the bobbin
thread is too loose, the needle thread will lie straight along the ·upper
surface of the material, thus:

Fig. 16. Tight Needle Thread Tension
If the tension on the bobbin thread is too tight, or if that on the needle
thread is too loose, the bobbin thread will lie straight along the under
side of the material, thus:
F1g 17. loose Needle Thread Tension
TO REGULATE THE TENSIONS
The tension on the needle thread is regulated by the thumb nut (Q,
fig. 18) at the front of the tension discs on the front of the machine. To
increase the tension, turn this thumb nut over to the right. To decrease
the tension, turn this thumb nut over to the left.
The tension on the bobbin thread is regulated by means of the screw
nearest the center of the tension spring on the outside of the bobbin case.
To increase the tension, turn this screw over to the right. To decrease
the tension, turn this screw over to the left.
TO REGULATE THE PRESSURE ON MATERIAL
To increase the pressure of the presser feet on the material, turn the
thumb screw (H, fig. 14), at the bock of the machine, downward. To
decrease the pressure, turn this thumb screw upward.
The pressure on the material should be sufficient to enable the feed
to move the work along evenly.

TO RAISE OR LOWER THE PRESSER FEET
The presser feet ore raised by pressure on the foot treadle and may
be locked in the raised position by moving the lever (D, fig. 2) all the way
to the left. A slight pressure on the treadle will automatically release
the locking device.
TO PREPARE FOR SEWING
With the left hand hold the end of the needle thread, leaving it slack
from the hand to the needle. Turn the machine pulley over toward you

F1g. 13. Pulling Up the Bobbin 1 hreud
until the needle moves down and up again toils highest point, thus catch"'0
the bobbin thread; draw up the needle thread and the bobbin thread will
come up with it through the hole in the feed dog. Lay the threads back
under the presser feet and close the slide.
TO COMMENCE SEWING
Place the material beneath the presser feel, lower the presser feel
and commence to sew, turning the machine pulley over toward you.
