THREAD TENSION
See Fig. 25.
The tension on the needle thread can
be tested only when the presser foot is
down.
The numerals “0” to on dial B,
indicate the different degrees of tension
that can be obtained.
When the tension has been correctly
set note the number at the indicator
line C, so that this setting may be regained
should the tension be altered for special
work.
To increase tension, turn the thumb nut
A gradually to the right (clockwise)
until the required tension is obtained.
Each higher number denotes increased
tension.
