3.4 Threading the Needle Thread

To set the two tension values proceed as follows:

–

Turn the regulating screw 6 so far back that the

tension of the leaf spring 7 is completely released.

–

Set the brake spring 5 accordingly by turning the

screw 4.

–

Insert the bobbin into the upper part of the bobbin

case and thread the looper thread as per the

illustration.

–

Insert the bobbin case with bobbin into the hook.

–

With a so-called air stitch pull the looper thread to

the top of the stitch hole with the aid of the needle

thread.

–

Pull off the looper thread at an angle of 45°. About

half of the tension value should be felt.

Then tighten the regulating screw 6 to the

recommended tension.

- Risk of Injury -

Turn the main switch off!

The thread path of the needle thread is shown in the

following illustrations.

For a, as far as possible, tension-free unwinding of the

threads from the thread stand thread through only one

thread hole of the unwinding arm.

The other thread holes are closed with the plugs found in

the accessories package.
