1.1 Principles of a CO2 Laser

LASER is the acronym for Light Amplification by Stimulated Emission of Radiation. A CO2 laser works by electrically
stimulating the molecules within a carbon dioxide gas mixture. When focused through a lens, this highly-intense and
invisible beam will vaporize many materials. Depending on the speed and intensity of the projected beam, a CO

laser may be used to engrave or cut through a wide variety of materials.

1.2 Safety Ratings

The LV-290 is equipped with a sealed carbon-dioxide laser that emits intense and invisible laser radiation with a
wavelength of 10.6 microns in the infrared spectrum. The laser system is designated as a Class 1 laser device,
meaning that the system is equipped with key safety features and an enclosed laser head to completely contain the
laser under normal use. One of the key safety features found on the LV-290 is a Class 2 red beam safety guidance
pointer (similar to a laser-pointer presentation pen) allowing the operator to see the exact location where the laser
beam will fire.
Even though the LV-290 is equipped with the most powerful laser to date, through proper usage and taking
necessary hardware safeguards, will make it an extremely safe machine.

When the front door and back door are open, machine becomes a Class 4 equipment and users must
wear goggles to operate the machine.

1.3 The Safety Interlock System

The  laser  system  is  equipped  with  a  safety  interlock  system  utilizing  magnetic  sensors  on  the  top  and side
access doors,  laser-activation  and door LED  lights  on  the  control panel. The magnetic sensors  will deactivate the
laser  when  either door is  open. At  this  time,  the  “door” LED  light  found  on  the control panel will illuminate,
indicating an open or improperly closed door. When the laser is in operation, the “laser” LED will illuminate to
inform the operator that the laser is activated. If at any time, any of the access doors are  open  and  the  “laser”
LED  is  illuminated,  IMMEDIATELY  unplug  the  laser  system  and  contact your authorized Roland DG Corporation
dealer.

WARNING

・

DO NOT operate the laser system if any component of the safety system is malfunctioning.

・

DO NOT attempt to remove or modify any component of the safety interlock system.

1.4 Safety Labels

According to CDRH standards, all fixed or removable covers that allow access to a laser beam must have an
appropriate laser warning labels attached to them. These warning labels must be clearly visible to the operator prior
to removing the cover. Additional labels must be applied to the interior of the machine and be visible in the event
when the covers are removed. A label clearly displaying the manufacturer’s name, date of manufacture, description
of product, model number, serial number, and compliance statement must be attached to the outer surface of the
machine
In compliance with CDRH standards, the required warning labels are affixed at the time of manufacture to the LV-
290, attached on appropriate locations. These labels are not to be modified in any way or removed for any reason.
Please familiarize yourself with the specific labels and their locations on the machine. Below is a list of all the safety
labels and their locations on the machine.
