To Remove the Work
Have the thread take-up lever at the highest point, raise the
presser feet, draw the work back and cut the threads close to the
goods. Lay the ends of the threads back under the presser feet.
Tens i ons
The needle and bobbin threads should be locked In the center of
the thickness of the material, thus:
Fig. 14. Perfect Stitch
If the tension on the needle threads Is too tight, or If that on
the bobbin tlireads Is too loose, the needle threads will lie straight
along the upper surface of the material, thus;
Fig, 15. Tight Needle Thread Tension
If the tension on the bobbin threads Is too tight, or If that on
the needle threads Is too loose, the bobbin threads will lie straight
along the under side of the material, thus:
Fig. 16. Loose Needle Thread Tension
To Regulate the Tensions
The tension on the needle threads Is regulated by the two thumb
nuts (N, Fig. 18) at the front of the tension discs cn the front of the
machine. To Increase the tension, turn these thumb nuts over to the
right. To decrease the tenslai, turn the thumb nuts over to the left.
The tension on the bobbin threads Is regulated by means of the
screw nearest the center of the tension spring on the outside of each
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 Length of Stitch
The length of stitch Is regulated by the feed eccentric (B, Fig, 17)
located on the arm shaft.
Fig, 17. Feed Eccentric. Arm Cap Removed.
To lengthen the stitch, loosen screw (C,Fig.17) turn the feed
regulating screw (A,Fig.17) over toward the left. To shorten the
stitch, turn this screw (A,Fig. 17) toward the right. When the desired
length of stitch Is obtained, securely tighten screw (C).
To Regulate the Pressure on Material
To Increase the pressure of the presser feet on the material, turn
the thumb screw (D, Flg.3), at the back of the machine, downward. To
decrease the pressure, turn this thumb screw upward.
The pressure on the material should only be sufficient to enable
the feed to move the work along evenly.
