| Symbols | Description |
|---|---|
 | WARNING: Refers to a potential Electrical Hazard to human body; It requires a procedure that, if not correctly followed, may result in bodily harm to you and/ or others. Do not proceed beyond the WARNING sign until you completely understand and meet the required conditions. |
 | CAUTION： Refers to a potential hazard on product. It requires a procedure that, if not correctly followed, may result in damage to the product or components. In order to ensure normal use of equipment, do not violate the requirement of the CAUTION sign. |
 | WARNING: Refers to a potential Laser Hazard. The symbol represents laser radiation. The symbol is pasted on laser output end. |
| NO SYMBOL | IMPORTANT： Refers to any information regarding the operation of the product. Please do not overlook this information. |
NOTE:
This Backpack Laser Cleaning Machine can emit the wavelengths ranged from 1060nm to 1100nm. Despite the radiation being invisible, the beam may cause irreversible damage to the retina. We suggest that you use appropriate laser safety eyewear when operating this device.

Specular Reflection
There are often numerous secondary laser beams produced at various angles in the output port of the laser. These divergent beams are produced when the primary beam of laser reflects off a smooth surface, and they are called specular reflections. Although these secondary beams may be less powerful than the total power emitted from the primary beam, the intensity may be great enough to cause damage to the eyes and skin as well as surface of materials.
WARNING:
◎ You must exercise caution to avoid/minimize specular reflections as these laser radiations are invisible.
-
Safety Instructions of Accessories
Optical accessories relevant to the laser, such as light-sensitive elements that may be damaged from exposure to the laser light,such as video cameras, photomultipliers and photodiodes, need related protections.
WARNING:
◎ The output light of Backpack Laser Cleaning Machine is strong enough to cut or weld metal, burn skin, clothing and paint. In addition, this light can ignite volatile substances such as alcohol, gasoline, ether and other solvents. During the operating process, the flammable materials around the laser must be isolated.

Optical Operating Instructions
We strongly recommend that you read the following procedures before operating the Backpack Laser Cleaning Machine:
（1）Never look directly into the Backpack Laser Cleaning Machine output port when the power is turned on;
（2）Avoid positioning the Backpack Laser Cleaning Machine and all optical output components at eye level;
（3）Equip with laser beam casing;
（4）Ensure that all personal protective equipment is suitable for the output power and wavelength range of the Backpack Laser Cleaning Machine;
（5）Use the Backpack Laser Cleaning Machine in a room with access controlled by door interlocks. Post warning signs. Limit the safety areas to operate the Backpack Laser Cleaning Machine;
（6）Please do not operate the Backpack Laser Cleaning Machine in darkened environments;
（7）Do not turn on the Backpack Laser Cleaning Machine without an optical coupling fiber or an optical output connector;
（8）Do not install or detach cutting heads or collimators when the Backpack Laser Cleaning Machine is active;
（9）Carry out commissioning, calibration and focusing at low output Carry out commissioning, calibration and focusing at low output power and then increase the output power gradually when the calibrating and focusing work is done;
（10）If the equipment is operated in a manner not specified in this document, the protection devices and performance of the equipment may be impaired and the warranty will be voided.
CAUTION:
◎ The output of the Backpack Laser Cleaning Machine is delivered through a lens with an anti-reflection coating. If the backward-stage light path of your Backpack Laser Cleaning Machine has the optical lens, please strictly inspect the lens of the output head and the backwardstage lens of the Backpack Laser Cleaning Machine, and ensure that there is no dust and any other impurity on the lens. Please note that any macroscopic attachment may cause extreme damage to lens or burn the Backpack Laser Cleaning Machine or any backward-stage light path equipment.
◎ For cleaning instructions of the lens, please refer to the "Optical Fiber Connector Inspection and Cleaning Guide".
◎ Hot or molten pieces of metal may be produced when the Laser Eraser is under operation. Exercise caution if debris is produced in operation.
◎ When you carry out commissioning and calibration of the laser output, you must set the laser output at low power level and then gradually increase the output power during checking the quality of the light spot emitted from the laser via an infrared viewer.
WARNING:
◎ Make sure that the individual protective equipment meets the output power and wavelength range of the laser.
◎ Never look directly into the optical fiber or the collimator, and make sure you wear the safety protective glasses in each operation.

Electrical Operating Instructions
We strongly recommend that you read the following procedures before operating the Backpack Laser Cleaning Machine:
（1）Make sure the shell of this equipment is properly grounded. Any interruption of the ground loop may result in personal injury;
（2）Make sure the power source connecting equipment is properly grounded;
（3）In order to further reduce fire hazard, replace the line fuses (if applicable) with the same types and ratings. The use of other fuses or material is prohibited;
（4）Make sure that the input AC voltage of the Backpack Laser Cleaning Machine is the voltage of the normal AC mains, and wires are connected accurately. Any incorrect wiring method may cause damage to people or instrument;
（5）The equipment does not have any part which can be maintained by operators, and all the maintenance operations must be finished by the professionals of LaserBuster
（6）To prevent electrical shock, do not remove enclosure, detach the laser without permission and damage the relevant signs;
（7）Any product with unauthorized dismounting shall not be subject to warranty.
WARNING:
◎ The input voltage of the Laser Eraser is single-phase AC current (220V AC), which may cause risk of electric shock. All the relevant cables and connection wires have potential hazards.

Environment Conditions and Precautions
For ensuring the safety of the laser working area, suitable enclosures shall be applied, including but not limited the laser safety signs and the interlocking devices. The gases, sparks and debris that can be generated from interaction between the laser and the work surface can pose additional safety hazards. Corresponding operators must be trained and examined and know the normal safety specifications for operating the Laser Eraser.
Meanwhile, it is important that the output components shall not be installed at eye level. Because of interaction of the laser and the metal material, the radiation of high-level ultraviolet light or visible light may be produced. Make sure that the laser is provided with the protective cover to prevent the eyes or other parts of human bodies from damage by radiation.
We recommend that you comply with the following operating measures to prolong the service life of the Backpack Laser Cleaning Machine:
（1）Do not expose the Backpack Laser Cleaning Machine to a high moisture/high temperature environment. Install the Backpack Laser Cleaning Machine in the cabinet with the function of temperature-humidity control and dust-free.
（2）Operation at higher temperature will accelerate aging, increase threshold current and lower slop efficiency. If the device is overheated, stop operation and contact LaserBuster.
CAUTION: ◎ Exercise caution to avoid damage to the device. ◎ If the Laser Eraser will be in an environment of less than 0 degrees Celsius, drain all coolant out of laser completely to prevent damage to the laser.
