may 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.
3. Fire safety
When the machine cuts or engraves a material, a high-density laser beam is used to irradiate
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 (on acrylic, in particular) is most likely
to produce an open flame.
Read the following warnings and suggestions carefully:
￮ Ensure that the workspace is well ventilated, so that the smoke can be discharged
properly.
￮ 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.
￮ 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.
