1. DESERIPTION OF PROPER USE

The sewing unit 7700 is designed for the sewing of light weight

material which generally consists of textile fibres or leather.

These material are commonly used in the garment and furnishing

industries.furthermore the 7700 may also be employed to perform

seams in so called technical textiles.

As these applications are relatively rare and extremely varied the

user is advised to evaluate any possible danger arising from such

applications DURKOPP ADLER AG will be pleased to assist.

Depending on the result of this evaluation suitable safety measures

have to be taken.

In general the 7700 may only be used for dry material.

The material thickness must not exceed 6mm when compressed by

thesewingfoot.

The material must not contain any hard objects as otherwise the

7700 must be operated with anneedle breakage protection shield.

Such needle breakage protection shield is not available at this

time.

Usable threads are spun threads or bulk threads made of textile

fibres with dimensions up to NM30/3.

Prior to the use of other threads any possible dangers arising there

from have to be evaluated andappropriate safety measures must be

taken if necessary.

The 7700 must only be installed and operated in a dry and clean

environment.

Any use in other environments may necessitate furthera measures

to be agreed upon.(see EN60204-3-1; 1990)

DURKOPP ADLER AG as a manufacturer of industrial sewing

machines assume that all personnel operating our products are

atleast semi - skilled and all operations and,where applicable their
