LASER RADIATION
Exposure to the laser output can result in serious eye injury. Avoid direct eye exposure.
For your convenience and safety, on Hypertherm products that use a laser, one of the following laser radiation labels
has been applied on the product near where the laser beam exits the enclosure. The maximum output (mV),
wavelength emitted (nM) and, if appropriate, the pulse duration is also provided.
Additional laser safety instructions:
• Consult with an expert on local laser regulations.
Laser safety training may be required.
• Do not allow untrained persons to operate the laser.
Lasers can be dangerous in the hands of untrained
users.
• Do not look into the laser aperture or beam at any
time.
• Position the laser as instructed to avoid unintentional
eye contact.
• Do not use the laser on reflective workpieces.
• Do not use optical tools to view or reflect the laser
beam.
• Do not disassemble or remove the laser or aperture
cover.
• Modifying the laser or product in any way can
increase the risk of laser radiation.
• Use of adjustments or performance of procedures
other than those specified in this manual may result
in hazardous laser radiation exposure.
• Do not operate in explosive atmospheres, such as in
the presence of flammable liquids, gases, or dust.
• Use only laser parts and accessories that are
recommended or provided by the manufacturer for
your model.
• Repairs and servicing MUST be performed by
qualified personnel.
• Do not remove or deface the laser safety label.
