4 Notes on use and maintenance
4.1 Needles and threads
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 4669 EEO only.
The machine is supplied with size 80/12 needles.
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 200/2. Because of their
high strenght and ability to slide with a low thread volume they are to be preferred
over a spun thread.
This machine has been set and sewn off with genuine GROZ-
needles.
No guarantee can be granted if the settings are modified for using
different needle types.
4.2 Inserting the needle (Fig. 7)
CAUTION! Danger of injury!
Switch off the machine electrically with the main switch S0 before
exchanging the needle.
Otherwise there is a risk of injury by crushing and needle piercing.
The curved shape of the needle dictates the position in the needle lever.
It just needs to be ensured that the needle shank is pushed in all the way in the
groove of the needle lever and that the needle clamping plate (1) is held tight by the
screw (2).
