Training Check-Off List:
In order to be certified to use the GCC Spirit, you must communicate your understanding of the following procedures and rules:
Never place flammable materials or liquids on or in the Laser Cutter when it is on or in operation. Liquid acetone, alcohol, and other chemicals are, and can release vapors that are, flammable.
When the printer is in operation do not put your fingers near any moving parts including belts, motors, or gears. Tie back long hair, jewelry, or clothing that can get caught in the moving parts of the machine.
The GCC Spirit uses a CO2 laser to cut materials. The CO2 laser is not in the visible light spectrum, but can cause permanent damage to eyes. Do not disable any of the machine’s safety features, designed to prevent its operation while doors are open. This can result in damage to eyes.
Electrical Shock Hazard
Don’t attempt to service the machine while the power is on.
Make sure to turn the fume extractor on during laser operation. If the fume extractor is not extracting, it could be clogged. Please contact the laser lead and do not operate the laser if this occurs.
Because the laser vaporizes/burns material to produce results its is important to never cut a material that releases caustic or poisonous gases. Refer to the Materials list for examples of what can and cannot be cut. If you are not sure what a material is that you wish to cut or your material does not appear on the list ask/contact a shop lead ([email protected]).
The list does not include all materials or materials that have “Trade Names”.
Never cut any variety of Vinyl or any material containing Chlorine.
Material (such as resinous wood, some acrylics) may dirty the lens faster than others. Awareness of the laser's decline in performance as multiple cuts are performed is required. Do not increase power as performance declines. Stop and clean the lens or contact the shop lead.
High volume users of the laser cutter must be certified to clean the laser in order to use it. To maintain proper operation of this device, high volume users are required to perform periodic cleaning of this tool in accordance with the cleaning certification. If you are in doubt as to whether or not you are a high volume user, as the shop lead. Non-high volume users can still receive the cleaning certification if they so desire.
With the exception of some cardboard and paper materials, the air assist should be on for all cuts (this is done via software, not to be confused with the fume extractor switch above the laser cutter).
Electrical Shock Hazard
Material (such as resinous wood, some acryclics) may dirty the lens faster than
Do not use the emergency stop to turn off the machine. Please follow the correct machine shut down procedure. The emergency stop should only be used during an emergency.
