To Regulate Needle Thread Tension

The tension on the needle thread can

be tested only when the presser foot is

down.

The numerals "0" to "9" dial X, Fig. 29

indicate the different degrees of tension

that can be obtained. The numbers do

not denote size of thread or amount of

tension.

When the tension has been correctly

set, note the number at the indicator

line Y, Fig. 29 so that this setting may

be regained should the tension be

altered for special work.

Fig. 29 To Regulate Needle Thread Tension

To increase tension, turn the thumb

nut Z, Fig. 29 gradually to the right

(clockwise) until the required tension is

obtained. Each higher number denotes

increased tension.
