Part 1: Safety
Overview
Please carefully read all instructions before attempting to operate the laser. Never operate or
test the laser without the water pump activated or with anything other than pure distilled
water as a coolant. Never attempt to operate the laser with the lid open or attempt to
override the magnetic lid interlock switch. Please inspect the laser tube carefully for any
shipping damage and contact us immediately via email if there are any issues—please include
your unit’s serial number and photos of the problem.
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. While this device employs the same technology as a handheld laser pointer, it is
potentially hazardous if its beam is directed into the eye.
General Operation Precautions
The laser operator should observe the following:
NEVER operate the machine with any of the panels removed. Be aware that removal of
any portion of the cabinet will expose a Class 4 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 FRONT ACCESS PANEL
UNLOCKED AND OPENED. Remember that the CO
2
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).
