Operation Manual
2 Intended Use
The Class 531 is a button sewer that can be used as intended to sew
light to medium weight material. Such material is normally material
made out of textile fibers or leather. Such sewing materials are used in
the clothing, domestic upholstery and automobile upholstery industry.
In addition it is possible t hat even so-called technical seams can be
done with this button sewer. However, here the operator (in
co-operation with DÜRKOPP ADLER AG) must assess the possible
risks because such applications are on the one hand comparatively
rare and on the other hand there is an enormous variety. Depending
on the results of this assessment suitable precautions may need to be
taken.
Normally only dry material must be processed with this button sewer.
The material must not be thicker than 9 mm if it is to be compressed
through the lowered sewing feet. The material must not contain any
hard objects. The button sewer must not be operated without an eye
guard.
The seam is normally created with sewing threads made of textile
fibers (cotton thread, synthetic thread or braided yarns) with the
following dimensions:
Class 531-211 50/3 - 120/3 thread thickness
If you want to use other threads you must also the assess risks arising
from this and if necessary take precautions.
This button sewer must only be installed a nd operated in dry, tidy
premises. If the button sewer is used in other rooms t hat are not dry
and tidy other measures will be required that will have to be agreed
(see EN 60204-31: 1999).
As a manufacturer of industrial sewing machines we assume that at
least skilled operating personnel work on our product s o that all the
normal conditions and if necessary their risks can be assumed to be
known.
