In this case the CO

laser is switched off via the software. Due to the laser safe-
ty regulations safety goggles must be worn.
2.3 Intended Use
The laser system must only be used for the treatment of material surfaces.
The surfaces are locally heated by intensive class 4 laser radiation and are modi-
fied thereby. These systems are mainly applied for marking of product surfaces
(dates, batch printing, serial numbers, etc.).
WARNING
The radiation produced by the laser system is of high energy and therefore im-
proper use represents a danger to persons or objects!
The laser system must only be installed in production sites with restricted access.
Examples for Improper Use and the Resulting Risks
• Never expose human beings or animals to laser radiation!
This might result in severe burns of eyes or skin.
• Never expose flammable materials to laser radiation!
Always ensure appropriate shielding of the laser beam! Errors during marking
on flammable materials (e.g. paper) might cause fires. Take suitable safety
measures by installing e.g. smoke or fire detectors, extinguishers, or similar!
• Never expose reflecting surfaces to laser radiation!
The reflected laser beam may cause the same dangers - in individual cases
even greater dangers - as the original laser beam.
• Never expose unknown materials to laser radiation!
Some materials are easily penetrated by the laser beam, although they seem
to be opaque for the human eye.
• Danger of explosion!
Make sure that the laser area is free of explosive materials or vapors!
• For safety reasons arbitrary modifications or changes to the laser mark-
ing system are forbidden and result in loss of warranty!
If a modification made by the user to a previously classified laser system
leads to a change of its performance data and/or its intended use that person
or organization performing the modification is responsible for a new classifica-
tion and labeling of the laser system. The person or organization is then re-
garded as »manufacturer«.
In this case a new risk assessment is required.
2.4 Maintenance and Service
The maintenance tasks described hereinafter should only be carried out by espe-
cially trained personnel.
The service tasks are exclusively to be carried out by service personnel of Video-
jet Technologies Inc. or one of their representatives. During these works the laser
system has to be operated in class 4. In Germany, the DGUV Regulation 11 »La-
ser Radiation« says that the responsible trade cooperative association and the
