10.Do not install or detach cutting heads or collimators when the laser is active.

11.Make sure that the laser is shut down and the power is off before you install or detach cutting heads or collimators.

12.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 laser is delivered through a lens with an anti-reflection coating. If the backward-stage light path of your laser has the optical lens, please strictly inspect the lens of the output head and the backward- stage lens of the laser, 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 laser 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 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.

4.Electrical Operating Instructions

We strongly recommend that you read the following procedures before operating the laser:

1.The power supply voltage of the laser equipment is three-phase alternating current 360-440VAC, 3P+PE. The laser equipment needs to be properly grounded during installation and installation. The external cables of the cabinet must be placed in metal trunking or metal pipes during installation. Pay attention to the safety of electricity during use to prevent electric shock injury .

2.When disassembling the laser, turned off the power first . If electrical injury occurs, corrective measures should be taken to prevent secondary injury. The correct treatment process: turn off the power, release the personnel safely, call help, and accompany the injured.

3.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 Maxphotonics.

4.To prevent electrical shock, do not remove enclosure, detach the laser without permission and damage the relevant signs. Any product with unauthorized dismounting shall not be subject to warranty.

WARNING:

◎ The input voltage of the laser is triple-phase AC current (360-440VAC, 3P+3E), which may cause risk of electric shock. All the relevant cables and connection wires have potential hazards.

5.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. Corresponding operators must be trained and examined and know the normal safety specifications for operating the laser.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 laser:

1.In order to ensure a good operating environment of the laser, reduce the risk of condensation, reduce the probability of failure, and prolong the service life.

It is strongly recommended to configure the air-conditioned room of the laser in advance. The air-conditioned room should be spacious enough to facilitate internal maintenance. It can guarantee the minimum free space around the laser is 1.0m. If space is limited, the air-conditioned room needs to be designed to be easy to remove and install.

2.It is necessary to provide sufficient installation space for the air-cooled water cooler, and to ensure sufficient water cooler exhaust. The minimum free space of the top of the air-cooled water-cooled fan is 1.5m, and the side plate of the air filter is 1m away from the wall.

3.It is forbidden to place the air-cooled water-cooled machine in the laser air conditioned room. Because the air-cooled water-cooling machine discharges a lot of hot air, the room temperature will rise rapidly, and finally the heat dissipation will be poor, causing the water-cooling machine high-pressure alarm and laser condensation alarm.

4.Do not expose the laser to a high moisture environment.

5.The device is equipped with cooling fans. Make sure that there is sufficient airflow to cool the laser, any objects or debris that cover the ventilation holes must be removed at all times.

6.Operation at higher temperature will accelerate aging, increase threshold current and lower slop efficiency. If the device is overheated, stop operations and contact Maxphotonics.

7.Ensure that the work surface is properly vented. There may be gases, sparks and debris generated from the interaction between the laser and the work surface, and they could pose additional safety hazard.

CAUTION :

◎ The device may be damaged with incautious operation.
