4.1
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 checked GROZ-BECKERT needles system 1717 VRUE
only.
Needles and threads
The machine is supplied with size 90 needles.
Notice: A perfect needle is of great importance for a good blindstitch.
Damages of the needle point which often can be made visible under
a magnifier only may deteriorate the sewing result. Replace your
needle in time!
We recommend twisted polyester filament threads of size 120/2. Because of
their high strenght and ability to slide with a low thread volume they are to be
preferred over a spun thread.
For special applications also transparent monofile nylon threads or covering
yarns can be used.
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 genuine
GROZ-BECKERT needles .
No guarantee can be granted if the settings are modified
for using different needle types.
4.2 Inserting the needle (Fig. 5)
A T T E N T I O N ! Danger!
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 needle shape determines its position in the needle lever. Attention should
be paid only to ensure that the needle piston in the prisma of the needle lever is
pushed to the stop and that screw (2) of needle clamping plate (1) is tightened
well.
