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 notexceed 6mm when compressedby

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.

Priorto the use of other threads any possible dangers arising there from have to be evaluated andappropriate safetymeasures mustbe 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 dangers are presumed to be known.
