Product Description; Proper Use - Duerkopp Adler 743-221 Operating Instructions Manual

1. Product Description

1.1 Proper Use

The 743-221 is a sewing unit which can properly be used for the
sewing of light to medium weight material.
Such material is, as a rule, material made up of textile fibers or of
leather. These materials are used in the garment, furniture and
automobile upholstry industries. Further, it may also be possible to
execute so-called technical seams with this sewing unit. Here,
however, the operator must in any case (Dürkopp Adler will be glad to
help) make an evaluation of the possible dangers since such
applications are, on the one hand, relatively seldom and, on the other,
the variety is immense. Dependent on the results of this evaluation, it
may be necessary to take suitable safety precautions.
Generally, only dry material may be worked with this sewing unit. The
material may not be thicker than 3 mm. The material may contain no
hard objects.
The seam is generally made with textile fibers of dimensions up to
40/NeB (cotton yarns), 65/2 (synthetic yarns) or 65/2 Nm (covering
twists). Those wanting to use other threads must first evaluate the
dangers arising therefrom and, if necessary, take appropriate safety
measures.
This sewing unit 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 60204-3-1:1990).
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.
