B4 MOPA Safety First

Security Statement

NOTE: 

Before using the laser engraving machine, please read this safety guide carefully.

It mentions situations that require special attention and includes warnings of unsafe practices that can cause damage to your property or even endanger your personal safety.

1. Laser Safety

• The machines use Class IV lasers. The lasers are very powerful and can cause eye injuries and burn the skin. It is recommended to wear laser goggles when using the laser engraver.
• Avoid exposing your skin to Class IV laser beams, especially at close range
• Teens must be supervised by parents while using the machine.
• Do not touch the laser engraving beam while it is switched on.

2. Material Safety

• Do not engrave materials with unknown properties.

• Materials recommended: 

  Metal, including stainless steel, aluminum, bronze, brass, alloy, etc,

  Plastics, including PP, PE, ABS, etc. 

3. Use Safety

• It is forbidden to point the laser to people, animals or any combustible object, whether it is in working condition or not.
• Use this laser engraving device only in accordance with all applicable local and national laws and regulations.
• Use this device only in accordance with this instruction manual and engraving software manual.
• DO NOT leave this device unattended during operation. Cut off all power to the machine and contact either our customer service or repair service if anything seems to be working abnormally
• Any untrained personnel who might be near the device must be informed the danger of the machine before operation

4. Electric Safety

• Only use this device with a compatible and stable power supply with less than 5% fluctuation in its voltage.
• Turn on the power to this device when it is well grounded.
• ONLY use this device with one hand at a time. The laser is powered by an extremely high voltage connection and placing two hands on the machine at one time during operation has the potential to create a closed circuit with the human body, resulting in electrical sock.
• The area around this laser engraver device should be kept dry, well ventilated, and environmentally controlled to keep the ambient temperature between 40-95°F (5-35°C). The ambient humidity should not exceed 70%.

NOTE: 

1) Adjusting the focus is a necessary prerequisite for laser engraving, please refer to Appendix 1 before engraving. 

2) Make sure to remove the plastic protective cover of the field lens before engraving to avoid damage to the field lens caused by laser burning.

Appendix 1: Adjust the focus

Press up or down button to lift or lower the laser head until the three red light point overlap, which is the best focal point. 

The measuring focal length of this machine is _______mm (110x110) and _______mm (200x200),and the measuring distance is the length from the bottom line of the laser head to the surface of the engraving material. 

This parameter is measured manually, and each device has different focal lengths due to changes in laser sources and field lenses.

Note: 

Before the machine is out of the factory, we have done red light correction (for 110mm lens). At the position where the three red light spots overlap, the laser emits the strongest light. However, due to transportation reasons, the focus point of the red lights you received may shift, and the focus point would not be the best focal length. Please operate as the following steps:

1.Place the stainless steel test plate on the machine table	2.lift up or down the laser head to the best focus point according to the number in handwriting above
3.Turn on the machine, connect the computer with the machine	4. Import the "TEXT" for testing, select the default parameters, and tick the "continuous part" button.
5. Press "red (F1)" to ensure it'll mark on the test material. Click "mark", and the laser would be continuously marking	6. Meanwhile, lift or lower the laser head and observe the obvious change of intensity of the laser beam. Stop when the it works with the strongest laser
7.At this time, loosen the screws for the two beams of the auxiliary red light	8. Manually adjust the relative position of the red light dots to make them overlap. And tighten the screws
