Protecting Yourself During Procedures
WARNING! Using controls, making adjustments, or performing procedures other than those
specified in the user documentation can result in hazardous radiation exposure.
Federal statutes define three types of personnel who can use laser products:
operators, maintenance personnel, and service personnel.
Laser Safety During Operation and Maintenance
An enclosed, Class 1 laser device incorporates redundant and fail-safe safety features to
prevent laser exposure during normal operation and routine maintenance. You must
not attempt to bypass or override any of these safety features during normal operation or
routine maintenance.
❑
Keep the Manual Override (service mode) key switch in the Normal position, and
remove the key. Only qualified service technicians should have access to the key.
❑
Do not bypass or override any interlock switch.
❑
If you see any sign of laser emissions escaping from the system during normal
operation or routine maintenance, immediately turn off the system and contact
IPG Photonics Customer Service.
❑
Read and obey all precautions posted on safety labels attached to the system.
❑
Do not open any doors or remove any covers from the workstation or laser
enclosures.
❑
If the workstation has an external laser, do not loosen or remove the beam tube
that connects the laser output to the beam delivery system input.
Personnel Description
Operators According to law, the primary function of the safety features in a laser
product is to protect the public and the system operator. The operator is the
person who operates the controls that cause the product to perform its
intended function. Often the operator is unfamiliar with the technical
aspects of the product and the hazards of laser radiation.
Maintenance
personnel Maintenance personnel keep the laser equipment running properly. They
perform tasks such as minor adjustments and replenishment of expendable
items.
Service

personnel
Service personnel perform service and repairs to the laser product. They
have the most training and expertise with the equipment and its hazards.
Service personnel also perform regularly scheduled maintenance that
requires access to potentially hazardous levels of laser radiation.
Only service personnel are permitted to bypass enclosure interlocks and
other safety systems, and must comply with necessary safety precautions as
required by law. Common service procedures include:
• Laser resonator alignment, cleaning, or replacement
• Beam quality checks
• Optics cleaning and replacement
• Beam delivery system adjustments
• Alignment of the laser beam to the workpiece
