1.1 Proper use
The Dürkopp-Adler 739-23 sewing machine has been specifically
designed for the processing of lightweight and medium weight
materials. Such materials generally consist of textile fibres and is used
in the clothing industry. The sewing machine can within certain
limitations also be used for technical seams. In this case, the operator
must ensure, that such applications are not carried out on a regular
basis and with a limited number of patterns and materials (please also
contact the Dürkopp Adler AG service department, who will be
delighted to assist you). Depending on the result, it might be necessary
to take suitable safety measures.
Generally, only dry material should be processed with this machine.
The thickness of the material may not exceed 3 mm when compressed
by the lowered sewing foot. The material may not contain any hard
objects. Otherwise, the operator must wear goggles. Suitable eye
protection is currently not available.
The seam is generally produced by textile threads (65/2 Nm for
synthetic fibres and 50/2 Nm for core spun. For other threads, the
operator must previously assess the risk involved and take suitable
precautionary measures.
The sewing machines may only be installed and operated in dry and
well-maintained rooms. If the sewing machine must be used in other
rooms,
additional measures might be necessary, that have to be agreed upon
by the manufacturer (see EN 60204-31: 1999).
As a manufacturer of industrial sewing machines, we assume that our
products are operated by personnel who are suitably trained, and we
thus assume that the general operation of machines and the potential
risks are known to the operating staff.
