General Safety

Read and get familiar with all safety precautions and procedures before using the machine. Strictly follow all safety precautions and ensure that the machine is properly assembled and is working properly.

Follow the operating principles:

• Check the machine for damage every time before you use it. Do not operate it in any way when any damage or defect is found.
• Ensure that the workspace is clean and flat. The laser tube is made of glass and is very fragile. If it is broken, the machine fails to work.
• Do not disassemble the machine or change its structure in any way without authorization. Do not modify or decompile its operating system.
• Do not leave the machine unattended when it is working. Pay attention to whether it is working properly.
  Keep the inside of the Laserbox clean. Residues and chippings accumulated during cutting and engraving are dangerous and may cause fire. Clean the chippings and residues in the honeycomb panel and tray regularly.
• The machine works properly at the temperature of 5°C to 25°C. Do not operate it at a temperature lower than 0°C.

Laser Safety

Generally, the laser tube works with a casing. Laserbox Rotary is equipped with a safety interlock switch. If the lid of the machine is opened during work, the laser stops processing and causes no harm to human bodies, with no need for special safety precautions.

Follow the safety precautions:

Do not operate the machine when any part of it (such as the tray) is removed. Removing any part may expose the laser system and cause damage to the machine. Note that CO2 laser beams are invisible.

Do not engrave or cut any material that contains PVC or vinyl (processed plastics are not recommended). These materials (and other materials containing chlorine/chloride) can generate corrosive vapor that is extremely harmful to the human body and may cause damage to the machine. Any damage caused by engraving or cutting any material containing PVC or vinyl is not covered by Makeblock’s warranty.

Do not engrave or cut any unknown materials. Vaporization/melting of many materials, which include, but are not limited to PVC and polycarbonate, may release harmful smoke.

Do not operate the laser when the lid is opened or the tray pulled out. Do not tamper with the safety mechanism of the lid.

Ensure proper connection with the smoke purifier before operation. Most materials produce pungent smoke when being processed, which include but are not limited to, paint, varnish, composite boards, and plastics that may generate hazardous compounds during laser processing.

The American National Standard for Safe Use of Lasers (Z136.1-2000) from the American National Standards Institute (ANSI) is the standard for reference on laser safety here. It is the fundamental document for relative federal regulations and the laser industry, and the laser safety guidance of the Occupational Safety and Health Administration (OSHA). It covers details on how to properly install and use lasers.

Fire Safety

When the machine cuts or engraves a material, a high-density laser beam falls on the material, heating up the surface of the material to vaporize it without burning. But most materials are inherently flammable and may be ignited to form an open flame that may burn down the machine (even if it is made of flame-retardant materials) and its surroundings. From our experience, using laser to perform vector cutting is most likely to produce an open flame. In particular, acrylic is proved to be extremely flammable in vector cutting.

Read the following warnings and suggestions carefully:

• Do not stack materials (especially organic ones, such as paper) around the machine. They may cause the spread of flames and increase the risk of material ignition.
• Do not leave the machine unattended when it is working. If the machine works with incorrect settings and is left unattended for a long period of time, or if a mechanical or electrical fault occurs, a fire may be caused.
• Clean the machine regularly. Excessive accumulation of residues and chippings from cutting and engraving may increase the risk of fire. Remove and clean the honeycomb panel and tray periodically to ensure that there is no residue or chipping inside the machine.
• Ensure that the area around the machine is clean without any cluttered flammable materials, explosives, or volatile solvents, such as acetone, alcohol, or gasoline. Keep a fire extinguisher and perform regular maintenance and inspection of it.

Electrical Safety

The laser tube of the machine has a silicone rubber casing, which can effectively shield the internal power cable from laser beams. If covers are loose and the internal power cable is exposed, stop operating and contact us for customer services.

Read the following warnings and suggestions carefully:

• Do not disassemble the machine when it is connected to a power supply. Otherwise, an electric shock may be caused.
• Do not touch any electronic area with your hands or other tools when the machine is connected to a power supply.
• You can power on or off the machine with the power switch on the rear panel. Press (-) to power it on and press (o) to power it off.
