7.4 Adjusting thread regulator

Caution, danger of injury!

Switch the main switch off.

Only adjust the thread regulator when the button sewer is switched

off.

The thread regulator 3 adjusts the amount of needle thread required to

form the stitch.

Only a precisely adjusted thread regulator guarantees optimum

sewing results.

If the adjustment is correct the needle thread loop must slide over the

thickest part of the hook with slight tension.

–

Undo screw 1.

–

Change the position of the thread regulator 3.

Thread regulator to the left = greater needle thread quantity

Thread regulator to the right = smaller needle thread quantity.

–

Screw up screw 1.

Adjustment note:

If the greatest amount of thread is required the thread take up spring

2 must be pulled down about 0.5 mm from its final upper position.

This is the case if the needle thread loop passes the maximum hook

diameter.
