Laser Safety
The output of the CO2 engraving laser is fully contained in a Class 1 enclosure during normal
operation. The laser cabinet has a safety interlock switch that deactivates the laser if the door is
opened during operation, and no special precautions are necessary to operate the high power
laser safely. However, the output beam of the Alignment Laser (visible red diode laser) is
accessible to the operator during normal operation, giving the total system an overall rating of
Class 3R. Class 3R lasers have minimal safety concerns when used properly and handled with
care. Follow these safety guideline at all times:
NEVER ​ operate the machine with any of the panels removed. Be aware that removal of any
portion of the cabinet will expose the laser system and greatly increase the risk of injury and/or fire.
Personal injury and fire risks are especially pronounced if the machine is operated with the bottom
panel removed. Remember that the CO2 laser beam is invisible!
NEVER ​ engrave or cut any material containing PVC or vinyl. These materials (along with other
chlorine/ chloride containing materials) produce a corrosive vapor that is extremely harmful to
humans and will destroy your machine. Your warranty will be void if your machine is damaged by
corrosion from engraving or cutting PVC or vinyl.
NEVER ​ engrave or cut any unknown material. The vaporization/melting of many materials,
including but not limited to PVC and polycarbonates, can give off hazardous fumes. Please refer to
the MSDS sheet from the material manufacturer to determine the response of any work material to
extreme heat (burning/fire hazard).
ALWAYS ​ use the air assist, especially while vector cutting. Vector cutting movements are
relatively slow and apply an extremely large amount of heat to the workplace. This buildup of heat
can create a significant fire risk.
NEVER ​ operate the Alignment Laser without the focus lens in place. The unfocused beam can be
reflected out of the chassis.
NEVER ​ operate the machine without a properly operating ventilation system. Most materials
produce an irritating smoke when engraved. Some materials, including but not limited to: paint,
varnish, composition board, and plastics, produce compounds that can be harmful if concentrated.
NEVER ​ look into the beam of the Alignment Laser (visible red diode laser).
