5.7.2 Adjusting the hook thread tension

Figure 14: Adjusting the hook thread tension

The braking spring (3) and tensioning spring (2) together

determine the hook thread tension. The braking spring (3) also

prevents the bobbin from running on when the thread is cut.

Correct setting

• The thread interlacing should be exactly in the middle of the

material being sewn ( Section 5.7 Thread tension,

page 27).

• If the loose thread end is held tightly, then the spool housing

should slowly lower through its own weight when the

bobbin (1) is full.

• The total value of the hook thread tension should be applied

50% respectively through the braking spring (3) and the

tensioning spring (2).

Risk of injury from moving parts.

Switch off the sewing machine before adjusting the

hook thread tension.
