• Do not use this product anywhere where fire is strictly prohibited, near inflammable gas, objects or
organic solvents such as thinner or gasoline, or in dusty place. There is a risk of fire.
• Do not use this product except for water-resistant part in wet place. In addition, never conduct wiring or
maintenance work with wet hands or when the product surface is wet. Otherwise, electric shock and/or
malfunction may result.
• Never disassemble the product.
Doing so may cause exposure to the laser beam or electric shock.
• Do not insert hands or objects between the gaps of the exhaust port or intake port. There is a risk of
electrical shock or injury.
• Be careful neither to give strong power to the fiber cable nor to nip it for installation. Do not install the
product to the systems that give excessive load acts on the fiber cable. If the fiber cable is damaged, laser
beam comes out from the cable and it may cause laser exposures.
• Take laser protection measures required to use Class 4 laser products subject to the local laws and
regulations of the country or region in which this laser product is used.
• To protect the operators' eyes, make it mandatory to wear goggles against laser beam
within the laser controlled area. The protective goggles can momentarily protect the
eyes against the scattered beam. Never look at the direct beam or reflected beam
even when you are wearing the protective goggles.
• Set a workpiece fixing jig and terminating object of the laser beam with a flame-resistant material which has
low reflectivity, in case of the radiation of the direct laser beam. Do not use the resin or specular objects for
a workpiece stand and terminating object.
• Construct an interlock systems such as a function to stop laser radiation for the maintenance door of the
protective enclosure.
• After power supply of the laser system is turned off, laser safety manager must remove the key and keep
it.
• Be sure to connect the head to the exclusive controller. It will cause exposure of laser beam and a failure
if it connects with any equipment other than the exclusive controller.
• Read all guides and manuals thoroughly, and do not operate, install and connect the laser system with
any other methods except the instructions provided in the manuals. If the product is used in a manner not
specified by the instruction, the safety protection and functions provided by the device may be impaired
and may cause injury, electrical shock or exposure of laser beam.
• Prior to wiring, cable connecting, and/or maintenance work, ensure that all the power switches are turned
off. Otherwise, electrical shock may result.
• The wiring and maintenance must be conducted by the electrical engineers or under their supervision.
Incorrect work may cause electrical shock.
• Connect ground wire before using. A failure or electrical leakage that occurs when the unit is not properly
grounded may result in electric shock.
