4 Notes on usage
4.1 Needles and threads
By selecting the most suitable needles and threads for the relevant sewing material
one can influence the sewing quality decisively.
Only tested GROZ-BECKERT needle system 1717 VRUE should be used.
The machine is supplied with needles of thickness 90/14.
NOTE: An intact needle is of decisive importance for a good initial stitch.
Bent needle points, which can in part only be visible under a
magnifying glass, impair the sewing result.
Therefore, exchange your needles in good time!
We recommend endless twined polyester threads with a thickness of 120/2. They are
to be preferred to a spun thread, due to their high strength and good sliding ability at
low thread volume.
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. 6)
C A U T I O N ! Danger of injury!
Before replacing the needle, switch off the machine electrically,
and depress the motor switch pedal to make sure that the
machine is truly switched off.
Otherwise there is a danger of injury from crushing and needle
punctures.
Due to the bent shape of the needle the position in the needle lever is given. Care
must only be taken that the needle piston is pushed in the slot of the needle lever up
to the stop and that the needle clamping plate (1) is tightened with the screw (2).
