TENSION
S
It is  | only  | normally necessary to adjust  | |||
the  | upper  | thread tension  | to  | achieve  | the  | 
correct balance between  | the  | upper  | and  | ||
lower threads.  | 
  | 
  | 
  | ||
The  | higher  | the number  | on  | the dial  | the  | 
greater the  | tension.  |

turning | the  | screw  | on  | the  | bobbin  | case  |

increase  | tension,  | the  |

As  | a  | general guide  | only,  | the  | user  | can  | achieve  | the correct | |||||||||
tension  | for  | normal  | sewing, by carefully susncriding the  | ||||||||||||||
wound bobbin | in its  | case  | by the  | thread.  | If  | the bobbin  | |||||||||||
and case  | immediately fall  | to  | the ground,  | the  | tension is too  | ||||||||||||
loose  | and  | should  | be  | increased.  | The  | 
  | correct  | tension  | is  | ||||||||
obtained  | when a slight jerk of  | the thread  | causes  | the bobbin  | |||||||||||||
to  | drop | a short | distance  | only.  | If this action  | does  | not move  | ||||||||||
the  | bobbin  | the  | tension  | is  | too  | tight  | and  | should be  | loosened  | ||||||||
until  | the  | desired effect  | is  | achieved.  |
