NOTE: When the machine Is equipped
with Cylinder End Cover Thread Cutter (No.
241230 complete), the bobbin thread can be
cut before removing the work from the cyl­
inder by moving the darn back over the
cutter until the bobbin thread enters the
nipper spring (A,Fig.10) and Is cut by the
cutter (B). The end of the bobbin thread
Is held In the nipper spring ready for the
next darn.

Tensions
The needle and bobbin threads should be locked In the center
of the thickness of the material, thus:
Fig. 11. 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. 12. 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 tha material, thus:
Fig. 13. Loose Needle Thread Tension
To Regulate the Tensions
The tension on the under thread Is regulated by the screw ( s .
Fig.17) In the center of the tension spring on the outside of the
11
bobbin case. To Increase the tension, turn the screw ( s ) over to
the right. To decrease the tension, turn the screw over to the
left. See that there Is no lint or dirt under the tension spring.
Correctly made stitches, as shown In Fig. 11, can usually be
obtained by regulating the upper tension only, turning the ten­
sion tliumb nut (C,Flg.3) Inward to tighten and outward to loosen
the tension.
