6.5 Winding on the looper thread

Caution - danger of injury !

Turn off the main switch.

The looper thread may be threaded for spooling only with

the sewing machine switched off.

The looper thread may be spooled only with the sewing

feet locked in the raised position.

–

If spooling is to take place when sewing with no underlaid material:

lock the sewing feet in the raised position (see section 6.9).

–

Thread the looper thread as shown in the illustration.

–

Wind about 5 loops of the looper thread anti-clockwise onto the bobbin core.

–

Place the bobbin on bobbin-winder shaft 2.

–

Swivel bobbin-winder lever 3 against the bobbin.

–

Adjust tension 1.

The looper thread should be wound on with minimal tension.

–

Sew.

The bobbin-winder lever 3 terminates the process as soon as the bobbin is full.
