Read and get familiar with all safety precautions and procedures before using the machine. Strictly follow all safety precautions. Ensure that the machine is properly assembled and is working properly.

1. Laser safety

Lasers are categorized into several different classes depending on the extent of the potential hazard associated with the laser, with Class 1 being the least dangerous and Class 4 the most dangerous. The United States Food and Drug Administration has indicated that Class 4 lasers may pose an “immediate skin hazard and eye hazard from exposure to either the direct or reflected beam; may also present a fire hazard.”

xTool M1 Ultra is Class 1 laser machine. The Class 1 laser machine includes a Class 4 working laser and a Class 1 indicator laser. Generally, the laser module is completely enclosed in the casing and light shield during operation to prevent human access to Class 4 laser radiation. The machine is equipped with safety interlock switches on the lid and baseplate. If the lid is lifted or the baseplate is removed during operation, the device will stop working.

 

Follow the safety precautions:

• Do not operate the machine when any part of it is removed. Removing any part may expose the laser system and cause damage to the machine.

• Laser operation is prohibited when the lid is lifted. Make sure that the lid is closed during operation and do not tamper with the safety mechanism of the lid.

• Do not leave the device unattended during operation. Pay attention to whether it is working properly.

The reference standards for laser safety are the American National Standard for Safe Use of Lasers (Z136.1-2022), International Electrotechnical Commission Standard (IEC 60825-1:2014), and European Standards (EN 60825-1:2014/A11:2021).

 

2. Chemical safety

A high-density laser beam is used by the device to irradiate the material to be cut or engraved, so as to heat up the material surface and vaporize the material without burning. But some materials may release toxic and harmful smoke or gases at a high temperature. Therefore, precautions are required for chemical safety during material processing.

 

Follow the safety precautions:

· Do not engrave or cut any material that contains PVC or vinyl (processing plastics is not recommended). These materials (and other materials containing chlorine/chloride) can generate corrosive vapor that is extremely harmful to the human body and can cause damage to the device. Any damage caused by engraving or cutting any material containing PVC or vinyl is not covered by the Company's warranty.

· Do not engrave or cut any unknown materials. Vaporization or melting of many materials, which include but are not limited to PVC and polycarbonate, may release harmful smoke.

3. Fire safety

A high-density laser beam is used by the device to irradiate the material to be cut or engraved, so as to heat up the material surface and vaporize the material without burning. But most materials are inherently flammable and may be ignited to form an open flame that can burn down the device (even if it is made of flame-retardant materials) and its surroundings. Experience shows that vector cutting with a laser is most likely to produce an open flame. In particular, acrylic has proven to be extremely flammable in vector cutting.

 

Read the following warnings and suggestions carefully:

• Equipment for use in locations where children are not likely to be present.

• Ensure that the workspace is well-ventilated so that the generated smoke can be discharged in time.

• Do not stack materials (especially organic ones, such as paper) around the machine (especially the end of the smoke exhaust pipe). They may cause the spread of flames and increase the risk of material ignition.

• Do not leave the machine unattended when it is working. If the machine works with setting errors and is left unattended for a long period of time, or if a mechanical or electrical fault occurs, a fire may be caused.

• Clean the device regularly. Excessive accumulation of residues and chippings from cutting and engraving would increase the risk of fire. The internal working area needs to be cleaned periodically to ensure that there is no residue or chipping inside the device.

• Ensure that the area around the machine is clean without any cluttered flammable materials, explosives, or volatile solvents, such as acetone, alcohol, or gasoline.

• Keep a fire extinguisher and perform regular maintenance and inspection of it.

• If a fire occurs during processing, take good care of yourself. For a small flame, you can wait for it to go off; for a larger fire, please keep a safe distance and use a fire extinguisher to put it out.

• It is recommended that you use xTool fire safety set when engraving or cutting the flammable materials with the laser beam to prevent the fire.

4. Electrical safety

Follow the safety precautions:

• Do not open any access panel on the device when the device is connected to the power supply. Accidental contact with the power supply may cause injury.

• Do not touch any electronic area with your hands or other tools when the machine is connected to a power supply.

5. Blade safety

· Prevent blade contact with your fingers when removing the laser module or blade, or you may get hurt.

· Blades are very sharp. Be careful not to hurt your hands when installing or replacing them.

· Place the used blades in a container that can prevent sharps from hurting people, such as a metal box, seal the container, and dispose of it.

6. Maintenance

Follow the operating principles:

• Check the machine for damage every time before you use it. Do not operate it in any way when any damage or defect is found.

• Ensure that the workspace is clean and flat.

• Do not disassemble the machine or change its structure in any way without authorization. Do not modify or decompile its operating system.

• Do not leave the device unattended during operation. Pay attention to whether it is working properly.

• Keep the inside of the machine clean. Residues and chippings accumulated during cutting and engraving are dangerous and may cause a fire. Clean the chippings and residues inside the work area regularly.

• The machine works properly at the temperature of 0°C to 35°C and can be stored properly at the temperature of –10°C to 40°C. Do not operate it at a temperature lower than 0°C.

• This product is not user-serviceable. It must be returned to the factory or repaired by authorized professionals.

• Cut off the power before maintaining the device.

• Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

7. Warning and instruction signs

On xTool M1 Ultra, the warning and instruction signs are labeled where physical injuries or damage to the machine may be caused before and/or during operation. If a sign is damaged or lost, replace it immediately. You can use the following template to print the sign you need.
