Instructions for use
The sewing quality can be influenced to a considerable extent by choosing the
most suitable needles and threads for the material to be sewn. It is
recommended to use controlled GROZ-BECKERT needles system 1669 EEO
or system 4669 EEO only.
Needles and threads
The machine is supplied with size 70 needles. There are also sizes 60, 65, 80
and 90 available.
Notice:
A perfect needle is of great importance for a good sewing result.
Damages of the needle point which often can be made visible under
a magnifier only may deteriorate the sewing result. Replace the
needle in time!
We recommend twisted polyester filament threads of size 120/2 or 200
respectively. Because of their high strength and ability to slide, combined with a
low volume they are to be preferred over a spun thread.
G u a r a n t e e d r e m a r k !
This machine has been set and sewn off with

No guarantee can be granted if the settings are modified

Inserting the needle
A T T E N T I O N ! Danger of body injuries!
Switch off machine electrically and confirm that the
machine is really in standstill position by operating the
treadle for the motor control before changing the needle.
Otherwise danger of finger bruises and needle
throughstitches.
The curved needle shape determines its position in the needle lever. Attention
should be paid only to ensure that the needle piston is pushed to the stop in the
channel of the needle lever and that the screw (4) Fig. 2 of the needle clamping
plate is tightened well.
