Regulating the Tensions
Upper:
When the presser foot lifter lever (Pig. 3) .
tension on the upper thread is automatically released
fore, the presser foot must always be lowered when ad‘
ing the upper tension. The tension regulator lever is f
on the face of machine (Fig. 3). To increase tension°'^*^^^
lever downward. To decrease tension push lever u n J * -
The most satisfactory tension for ordinary sewing is '
with pointer on this lever set between figures 2 and ^
numbered gauge.
Lower:
The small screw in center of the bobbin case (Pig B\
regulates the tension on the lower thread. To increase ten
sion tighten the screw; to decrease tension, loosen it. in
either event only turn this screw a little bit at a time.
Tension should be in balance to get best results________ neat
fiexible, accurate stitching. Experiment until your stitching
is balanced as follows:
■
If the upper thread is too tight, the upper thread will be
drawn straight on the top of the material, thus:
If the lower thread is too tight, the lower thread will be
drawn straight on the bottom of the material, thus:
When tensions are properly adjusted the stitching on
materials will look the same on both aides, thus:

To Remove the Work
The take-up (5, Fig. 3) must be at its HIGHEST POINT
hpfore attempting to remove the work. Failure to do this will
° in breaking the thread and unthreading the needle.
Turn the hand wheel until the take-up (5, Pig. 3) is at
ffc highest point, raise the presser foot with presser foot lever
snd DRAW THE FABRIC BACK about three inches in a
straight line, pass both threads over the thread cutter on the
nresser bar. After the material has been removed and the
threads cut, do not run the machine accidentally or other­
wise without material under the presser foot. (See following
paragraph.)
IMPORTANT—When the machine is threaded, do not
operate it without having material
under the presser foot.
Failure to observe this instruction will cause thread to
lodge in the shuttle mechanism and prevent machine from
