2. Designated use

The designated use of the 767 sew ing machine is sewing light to medium-heavy

materials. Such material is generally made of textile fibres, but it may also be leather. It

is used in the clothing industry and for domestic and motor-vehicle upholstery.

This sewing machine can also be used to produce so-called technical seams. 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, they are so varied that no single set

of criteria can c over them all. The outcome of this assessment may require appropriate

safety measures to be taken.

Generally only dry material may be sewn with this machine. The material may be no

thicker than 10 mm when compressed by the lowered sewing feet. The material may not

contain any hard objects, since if it does the machine may not be operated without an

eye-protection device. No such device is currently available.

The seam is generally produced with textile-fibre sewing thread of gauge 11/3 Ne

(cotton),

11/3 Nm (synthetic) or 11/4 Nm (covering yarn). Before using any other thread the possible

dangers arising must be assessed and appropriate safety measures taken if necessary.

This sewing machine m ay be set up and operated only in dry, well-maintained premises.

If the sewing machine is used in other premises which are not dry and well-maintained it

may be necessary to take further precautions (which should be agreed in advance - see

EN 60204-31: 1999).

As manufacturers of industrial machinery we proceed on the assumption that personnel

who work on our products will have received training at least sufficient to acquaint them

with all normal operations and with any hazards which these may involve.
