products (according to article 8, EN 60825-1)
4-General Safety Instructions
1、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!
2、Safety Instructions of Accessories
The photosensitive elements integrated in laser-related optical accessories may be damaged by laser exposure, such as video cameras, photomultiplier tubes, and photodiodes. Attention should be paid to related device protection.
WARNING :
◎ The Maxphotonics MFSC laser light 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.
3、Optical Operating Instructions
We strongly recommend that you read the following procedures before operating the laser:
1、Never look directly into the laser output port when the power is turned on.
2、Avoid positioning the laser and all optical output components at eye level.
3、Equip with laser beam casing.
4、Make sure to remove the tail cover of the laser output head before the laser is turned on, otherwise it will cause irreversible damage to the laser fiber output head.
5、Ensure that all personal protective equipment is suitable for the output power and wavelength range of the laser.
6、Use the laser in a room with access controlled by door interlocks. Post warning signs. Limit the safety areas to operate the laser.
7、Please do not operate the laser in darkened environments.
8、Do not turn on the laser without an optical coupling fiber or an optical output connector.
9、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、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.
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、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 laser is the voltage of the normal AC mains (Three-phase four-wire 360-440VAC), and wires are connected accurately. Any incorrect wiring method may cause damage to people or 12 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 Maxphotonics Co., Ltd.
6、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), 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、Do not expose the laser to a high moisture environment.
2、Operation at higher temperature will accelerate aging, increase threshold current and lower slop efficiency. If the device is overheated, stop operations and contact Maxphotonics.
3、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

Chapter 7: Fiber Connector Inspection and Cleaning Guide
1-Notice
It is imperative that the fiber connector is checked for dust, dirt, or damage every time it is connected to any optical device, before use. The use of a
dirty or damaged fiber connector can result in serious injury and/or laser damage. Maxphotonics is not responsible for any damage due to contaminated connectors.
For cleaning a fiber connector, you need the following materials:
1、Powder-free rubber gloves or fingerstall
2、Lint free optical cleaning wipes and/or swabs
3、Ahydrous ethanol (Optical level, pure >99.5%)
4、Acetone (Optical level, pure >99.5%)
5、Compressed air (oil free, water free)
6、Microscope
7、Light source
IMPORTANT :
◎ It is imperative that you wear powder-free rubber gloves during this cleaning procedure! It is hereby stated that damage to the fiber connector can occur due to mishandling, the use of incorrect cleaning procedures, or chemicals for cleaning. This is not covered by the Maxphotonics’ warranty. Ahydrous ethanol and acetone should be managed and stored according to the local law and instructions.
2-Operating Procedures
Clean and maintain the fiber laser according to the following procedures:
1、Switch off the laser power, and place the key switch on position of “OFF”
2、Remove the black outer protective sleeve and leave the white inner cap on and clean the fiber connector exterior with optical cleaner, wipe it with a clean optical wipe and dry it with compressed air;
3、Place fiber connector in the holder of the microscope;（7-1）
4、Remove the protective inner cap from the connector;（7-2）
5、Focus the microscope onto the connector surface;
6、Use a light source to illuminate the face of the fiber connector so that the light is reflected off the surface of the endface. This is achieved if you see a bright golden shine from the QBH connector endface.
7、Inspect the endface surface carefully. Contamination will lead to dark spots/burns on the surface and possibly damage to the fiber and/or laser. If contamination is visible on the endface, cleaning is necessary.
8、Take out the cap and sleeve, then connect the fiber connector with the cutting head quickly and fasten them. (Place the cap face down on a clean surface or a lint-free wipe.)
IMPROTANT :
◎ Do not reuse a lint-free optical wipe or swab.
◎ Do not touch the protective lens of the fiber connector.
◎ Do not blow directly, or else new dirty will be brought.
◎ Do not touch the tip of the cleaning swab with your fingers.
◎ Cleaning is necessary before place the protective cover and sleeve.
◎ Never blow air directly at the surface, because you could imbed contaminants into the surface. Always blow across the surface!
◎ If the fiber connector could not be installed in optical system immediately, please cover it with the protective cap cleaned with compressed air.
CAUTION :
◎ It is hereby stated that damage to the fiber connector can occur due to mishandling, the use of incorrect cleaning procedures, or chemicals for cleaning.
This is not covered by the Maxphotonics’ warranty.
