2.2 Proper Use, Designated use
The 667 is a sewing machine designed for sewing light to medium-heavy
material. Such material generally consists of textile fibres, but can also
include leather. It is used in the clothing industry and for domestic and vehicle
upholstery.
This special sewing machine can also be used to produce so-called technical
s
eams. In this case, however, the operator must assess the possible dangers
which may arise (with which DÜRKOPP ADLER AG would be happy to
assist), since such applications are, on the one hand, relatively unusual and,
on the other, so varied that no single set of criteria can cover them all. The
outcome of this assessment may require appropriate safety measures to be
implemented.
Generally-speaking only dry material should be sewn with this machine. The
ma
terial should be no thicker than 10 mm when compressed by the lowered
sewing feet. The material should not contain any hard objects; if it does, the
machine should only be operated with eye protection. No such eye protection
can currently be provided.
The seam is generally produced with textile-fibre sewing thread of gauge up
to
15/3 NeB (cotton), 15/3 Nm (synthetic) or 15/4 Nm (covering yarn). Before
using any other thread the possible dangers arising must be assessed and
appropriate safety measures implemented if necessary.
This special sewing machine should only b
e set up and operated in dry, well-
maintained premises. If the sewing machine is used in premises which are not
dry and well-maintained,
it may be necessary to implement further precautions (which should be
ag
reed in advance - see EN 60204-31:1999).
As manufacturers of industrial sewing machines, we proceed on the
assumption that personnel who
work with our products will have received
training that is at least sufficient to acquaint them with all of the normal
operations and with any hazards that these may involve.
