4WARNING• Do not use this product anywhere where fire is strictly prohibited, near inflammable gas, objects or organicsolvents 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 ormaintenance work with wet hands or when the product surface is wet. Otherwise, electric shock and/ormalfunction 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 ofelectrical shock or injury.• Take laser protection measures required to use Class 4 laser products subject to the local laws andregulations 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 beamwithin the laser controlled area. The protective goggles can momentarily protect theeyes against the scattered beam. Never look at the direct beam or reflected beameven when you are wearing the protective goggles.• Set protective enclosure with proper reflectance, durability and thermal resistance to enclose the laserradiation area without leakage.• Construct an interlock systems such as a function to stop laser radiation for the maintenance door of theprotective enclosure.• After power supply of laser marker is turned off, laser safety manager must remove the key and keep it.• Be sure to connect the head and controller (for LP-RV series, the head, controller and oscillator unit) of thelaser marker which have the same model number. Otherwise there is a risk of exposure to laser radiationor failure.• Read all packaged guides and manuals thoroughly, and do not operate, install and connect the lasermarker with any other methods except the instructions provided in the manuals. If the product is used in amanner not specified by the instruction, the safety protection and functions provided by the device may beimpaired 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 turnedoff. 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 properlygrounded may result in electric shock.• For LP-RF/LP-RV series, be careful neither to give strong power to the fiber cable nor to nip it forinstallation. Do not install the product to the systems that give excessive load acts on the fiber cable, suchas head movement unit. If the fiber cable is damaged, it may cause laser exposures.ME-LP-GS-SR-COMP-3
