Notes on usage
4.1
Needles and threads
The sewing quality can be improved by using the most appropriate needles and
threads for the goods to be produced.
Only use approved STROBEL needle system 1669 EEO or system 4669 EEO.
The machine is delivered with needles of size 80.
Furthermore, needle sizes 60, 65, 70 and 90 are also available.
Note:
An intact needle is very important for ensuring good quality stitches.
Bent needle tips, that may only be visible under a magnifying glass,
will lead to poorer sewing results. Replace your needles in time!
We recommend using twined polyester tread of thickness 120/2 or 200. Due to
their high strength and good sliding behaviour at a small thread size, they are
preferable to spun thread.
Guarantee note!
This machine has been configured and broken in using
original Strobel needles
.
No guarantees can be given when the machine is
readjusted for the use of different needles.
4.2
Inserting the needles
CAUTION!
Injury hazard!
Before replacing needles, switch off the machine and
depress the motor switch pedal to ensure that the
machine is truly at a standstill.
Otherwise there is a danger of finger injuries and needle
punctures.
The bent shape of the needles determines the position of the needle lever. Only
ensure that the needle shank can be pushed into the groove of the needle lever
until it stops and the needle clamping plate is tightly fastened using the screw
