1. Product description
1.1 Description of proper use
The 745-34 is a sewing unit which can properly be used for sewing
light to medium-weight material. Such material is, as a rule, material
made of textile fibres or leather. These materials are used in the
garment industry.
In general only dry material should be sewn on this machine. The
material must not contain any hard objects.
The seam is generally made with core thread, polyester fibre
or cotton threads.
The dimensions for needle and hook threads can be taken from the
table in chapter 2.4.
Before using any other threads it is necessary to estimate the
consequential dangers and to take the respective safety measures, if
required.
This sewing unit must only be installed and operated in dry and
well-kept rooms. If the sewing unit is used in other rooms, which are
not dry and well-kept, further measures to be agreed upon may
become 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 usual operations and, where applicable, their risks are
presumed to be known.
