1. Product Description

The DÜRKOPP ADLER 271-274 are universally employable special sewing machines.

2. Proper Use

The 271-274 are special sewing machines which can properly be used for the sewing of
light weight material. Such material is, as a rule, material made up of textile fibers or
leather. These materials are used in the garment and home upholstery industries.
Further, it may be possible to also conduct so-called technical seams with these special
sewing machines. Here, however, the operator (DÜRKOPP ADLER would be pleased to
collaborate) must make an evaluation of the possible dangers because such
applications are, on the one hand, comparatively rare and, on the other, the variety is
immense. Dependent on the result of this evaluation, appropriate safety measures are
to be taken.
Generally, only dry material may be worked with these special sewing machines. The
material may be no thicker than 6 mm when pressed together by the lowered sewing
foot. The material may not contain any hard objects because otherwise the automatic
sewing unit could only be operated with eye protection. Such eye protection is not
available at this time.
The seam is generally sewn with sewing yarns of a dimension up to 30/2 Nm (synthetic
threads) or 30/3 Nm (core spun threads). Those desiring to use other threads must first
estimate the dangers arising therefrom and, if necessary, take appropriate safety
measures.
These special sewing machines may only be installed and operated in dry and clean
premises. If the sewing unit is used on other premises which are not dry and clean,
further measures, which are to be agreed upon, may be necessary (see
EN 60204-31:1999).
We, as a manufacturer of industrial sewing machines, assume that at least semi-skilled
operating personnel will be working on our products so that all normal operations and,
where applicable, their dangers are presumed to be known.
