1. Description of product
1.1 Description of proper use
The 745-34 Speedpocket is a sewing unit determined to sew light to
medium-weight material, i.e. fabrics made of textile fibres or leather.
These materials are used in the clothing industry.
Generally only dry material should be processed with this machine. It
should not contain any hard objects.
In general, the seam is 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
consequent risks and to take corresponding safety measures, if
required.
This sewing unit must be installed and operated in dry and well-kept
rooms only. If it is operated in other rooms, which are not dry and
well-kept, further measures, which are to be agreed upon, can become
necessary (see EN 60204-31:1999).
We, as a manufacturer of industrial sewing machines, take it for
granted that at least semi-skilled operators will be working on our
products so that we can assume that all usual operations and, where
applicable, their risks are known to them.
