2.0 SAFETY
Laser Safety Information
• Laser systems are classified into 5 safety classess which assess their potential dangers: 1, 2,3a,
3b, and 4. All InkSmith Mako Laser Cutter is a device of class 2 (USA: Class II). This is guaranteed
by the protective housing and the safety installations. Please note that improper operation of the
device can override the status of safety class 2 and can cause the emission of harmful radiation.
• This laser system contains a carbon dioxide (CO2) laser source of class 4 that emits intensive and
invisible laser radiation. Without safety precautions the direct radiation or even diffuse reflected
radiation is dangerous.
• Without safety precautions, the following risks exist with exposure to laser radiation:
- Eyes: Burns to the retina from NIR (Near Infra Red) LASER
- Burns to the cornea from CO2 Laser
- Skin: All types of burns
- Clothing: Danger of fire
• Never try to modify or disassemble the laser on your own and do not try to start a system that has
been modified or disassembled.
• Dangerous radiation exposure can result if the use of operation or adjustment of equipment
other than is anything that described here, and/or if different operational methods are
performed.
• Dangerous radiation exposure can result from the use of prohibited materials such as:
- blank or polished metals
- metals with very high reflectivity like copper, brass, gold, sand silver
- any materials with highly reflecting coatings
• Other highly reflecting materials, especially in combination with high laser power, low processing
speed and/or work pieces with curved or inclined surfaces, might reflect laser radiation towards the
protection cover. With a very low probability this protection cover could be damaged if the reflected
radiation is FOCUSED onto the surface of the protection cover. Therefore visual inspection for point-
like defects on the protection cover should be done if the aforementioned conditions occur.
• If you detect such damages on the protection cover, immediately turn off the laser machine and
contact InkSmith to request a new protection cover.
