CO₂Laser Safety & Policies
WARNING: The safety precautions below are mandatory guidelines that must be
followed. LightObject will not be held responsible for damages or injuries resulting
from improper use of the laser machine.
DO NOT operate the laser machine until you have been properly trained.
DO NOT make contact with any exposed wires on the machine.
DO NOT use any unapproved or unsafe materials such as Polyvinyl Chloride (PVC) which emits
noxious gases that can harm your central nervous system.
DO NOT operate the laser near flammable/explosive substances.
DO NOT engrave on shiny metal or mirror as the laser beam can be reflected and deviate that
may result in blindness or burn.
NEVER look directly at the laser while in operation and avoid exposure to laser.
NEVER set anything on top of the laser and/or on the worktable when not in use.
NEVER leave the laser machine running while unattended. Monitor the machine when it is running
at all times to be able to hear and observe abnormalities and potential hazards.
NEVER push or pull on the laser head housing or gantry while the laser is running.
NEVER dismantle the laser machine as there are laser and high voltage parts that could harm or
result in injury.
NEVER open the upper cover of the laser machine while it is running.
ALWAYS wear proper goggles during machine operation.
ALWAYS unplug the machine before making any further adjustments.
ALWAYS keep hands away from machine while operating and stand clear from laser tube area.
In Case of an Emergency:
TURN OFF the POWER SWITCH of the machine OR
Press the EMERGENCYSTOP button
Fire & Hazardous Materials
WARNING: Leaving the machine unattended while in use can result in a fire and substantial
damage to the machine and the building it resides in. Any damage caused by fire that is not due
to defects in workmanship or the machine itself will NOT be covered by the LightObject warranty.
Hazardous Materials: Any materials considered hazardous are NOT recommended to etch, cut or
engrave. These materials can produce toxic fumes or cause the machine to not function properly.

First Time Laser Setup
The following components are required for operating the laser machine:
Air Assist: to blow smoke away from the beam, preventing damage to the lens and preventing
burning the material.
Water Chiller: to circulate cool water into the laser tube to prevent the tube from overheating. The
laser tube needs to be at a cool temperature of 15C - 25C or else the laser tube may overheat
and potentially crack.
Silicone Tubing for Water Chiller and Air Pump: 2 hoses to transfer water for cooling of the laser
tube and 1 hose to blow air around the laser head.
Air Exhaust Hose and Air Exhaust Fan: to provide ventilation removing fumes from laser machine.
Unpacking and Setting Up the Machine
1) Uncrate/unwrap the laser machine
2) Open up the laser machine and retrieve all accessories that may be inside the machine when
shipped.
3) Once all of the accessories have been removed, you are now ready to begin setting up the
machine.
4) Depending on the size of your laser tube, you may need to remove the side panel and install
the laser tube extension case. If laser tube is short, it can be installed before we ship it.

5) Place the laser tube on the laser tube mounts.
6) Connect the water tubing to the laser tube.

P. 9
7) Be sure to connect the silicone tubing on both sides of the laser tube. Connect water tubing
between chiller and machine. Chiller’s outlet goes to machine’s inlet. Machine’s outlet goes to
Chiller’s inlet. The correct direction of water flow is from high voltage side (red wire) of the
laser tube to the low voltage side.
(Chiller’s back side for reference only)
Note: The water temperature should always be between 59-77 degrees Fahrenheit when
running the machine. (15-25 Degrees Celsius).
8) Fill up the water chiller with distilled water and power up, observe the water flow direction.
Switch the inlet/outlet if it is wrong.
9) Check air bubble trapped in the laser tube. Squeeze the water tubing or tilt the laser tube
carefully to get rid of the big bubble. Small bubbles are acceptable.

rev. 0.4
P. 10
IMPORTANT: if large bubbles are present when the laser is firing, the tube can crack.
Check for bubble every time the water chiller is turned on.
10) Secure the laser tube on the laser tube mounts. For laser beam alignment, paper can be
placed between the tube mount and laser tube to adjust the position.
11) For screw type connection, clamp the wire under the screw. Put the rubber cap back on the
tube on the high voltage side.
