2. Proper Use

The 381 - 382 are special sewing machines which can properly be used for sewing light
sewing material. Such material is, as a rule, fabric composed of textile fibers or leather.
These sewing materials are used in the garment and furniture industries.
Furthermore, it may be possible to also execute so-called technical seams with this
special sewing machine. Here, however, the operator (DÜRKOPP ADLER AG would be
pleased to help) must make an evaluation of the possible dangers since such
applications are, on the one hand, relatively rare and, on the other, their variety is
immense. Depending on the results of this evaluation it may be necessary to adopt
appropriate safety measures.
In general, only dry material may be worked with this special machine. The material
may not be thicker than 8 mm when it is pressed together by the lowered sewing feet.
The material may contain no hard objects because otherwise the sewing unit could only
be allowed to be operated with eye protection.
Such eye protection is not available at this time.
The seam is generally made with sewing yarns of textile fibers with dimensions up to
30/2 Nm (synthetic threads) or 30/3 Nm (core spun threads). Those wishing to use
other threads must also first evaluate the dangers arising herefrom and, if necassary,
take safety measures.
This special sewing machine may only be installed and operated in dry and clean areas.
If the sewing unit is employed in other areas, which are not dry and clean, other, to be
agreed upon, measures may become necessary (see EN 60204-3-1: 1990).
We, as a manufacturer of industrial sewing machines, assume that, at a minimum,
semi-skilled operating personel work on our products so that all normal operations and,
where applicable, their dangers can be presumed to be known.
