1.2 Safety Symbols

Safety symbols in Quick Start Guides and User Manuals instruct you to avoid damage or hazards during machine assembly and use.

1.3 Safety Measures

• This laser engraving and cutting machine should only be used by trained operators aged 18 and above.
• Read the entire manual before use.
• The small percentage of the population (0.01%) that have blue-yellow color blindness (tritanopia) may struggle to see the laser lights and may not realize that the laser engraving and cutting machine is turned on. Tritanopic users must therefore be particularly careful.
• Operate the machine wearing the Laser Safety Goggles and other protective equipment such as a mask or using the Enclosure.
• The Laser Module is a class 4 laser product. You should operate the Laser Module only if you have sufficient knowledge of the physical properties of laser radiation, Laser Hazard Classes and associated health implications, and safety measures.
• This machine should be used exclusively for recreational purposes.
• Do not operate the laser while tired or under the influence of drugs, alcohol, or medication.
• Never expose yourself to the laser beam. Proper use and care of the Laser Module are essential to safe operation.
• Keep children and bystanders away while operating this machine.
• Do not reach inside the machine or touch the moving parts while the laser engraving and cutting machine is in operation.
• Do not leave the laser engraving and cutting machine unattended while it is on.
• Operate the laser engraving and cutting machine in a well-ventilated place or with an air purifier.
• Remove any reflective material from the work area underneath the Laser Module, as it can cause scattered radiation.
• Always operate this machine indoors on a solid horizontal table or workbench.
• Do not expose this machine to rain or wet conditions.
• Always disconnect the power supply before maintenance or modifications.
• Turn off the machine immediately if any of the following occurs:
  • Open flames appear.
  • The machine stops unexpectedly.
  • Any damage is incurred to the interior components of the laser engraving and cutting machine.
  • Any unusual light or sound comes from the machine which has never occurred previously.
• In all EU member states, operation of 5150-5250 MHz is restricted to indoor use only.

1.4 Emergency Response

1.4.1 Eye Injury from Laser

Should your eyes be exposed to direct or scattered laser beams, take the following steps as an emergency response:

(1) Grab a nearby thick and opaque object to block the laser beam to prevent further exposure to laser.

(2) Shut down the laser engraving and cutting machine immediately.

(3) If an eye injury is suspected, medical examination by a qualified specialist needs to be carried out as soon as possible.

(4) If an eye injury is apparent, call the local hospital for emergency help.

If a medical emergency occurs in which the extent or nature of the injury precludes you from further actions, sit down on the floor and yell for help. Warn any respondent of laser danger and ask them to turn off the laser engraving and cutting machine before sending you to the hospital.

1.4.2 Skin Injury from Laser

Lasers can harm the skin via photochemical or thermal burns, which can be treated as could any other burn. Take the following steps as an emergency response:

(1) If it is a major burn, call for emergency medical care before you take the subsequent steps.
(2) Remove any clothing or jewellery that's near the burnt area of skin, but do not move anything that's stuck to the skin.
(3) Hold the burn under cool or lukewarm running water until the pain subsides. Use cool, wet compresses if running water isn’t available.
(4) After the burned area has been cooled, use painkillers such as paracetamol or ibuprofen to treat any pain.
(5) Loosely bandage the burn. Use a sterile, non-adhesive bandage or clean cloth.

1.4.3 Exposure to Gases or Fumes

The heating which occurs during laser cutting or engraving can cause charring, pyrolysis, and even combustion of the material being worked on and generate gases or fumes.

• Airway Irritation

Gases and fumes may irritate the airways and potentially be extremely dangerous. Should airway irritation occur, take the following steps as an emergency response:

(1) Expose the casualty to fresh air.
(2) Call for medical help.
(3) If the person is unresponsive, not breathing, or not breathing normally, perform CPR until the person begins breathing or emergency help arrives.

• Eye Irritation

Being exposed to gases or fumes may cause the eyes to become red and watery, and induce a grainy feeling. Should eye irritation occur, take the following steps as an emergency response:

(1) Rinse the affected eyes with room temperature water for 10 to 20 minutes to relieve symptoms. Sterile water or sterile normal saline solution (0.9%) from sealed disposable containers can be used. Press the eyelids wide open and keep them apart while rinsing.
(2) Transfer the casualty to the hospital as soon as possible for an eye examination and further treatment.

• Asthma Attacks

Gases or fumes may trigger asthma in a person with asthma history. Should an asthma attack occur, take the following steps as an emergency response:

(1) Sit the person upright.
(2) Give 4 puffs of blue reliever puffer. Ensure you shake the puffer, put 1 puff into a spacer at a time, and get the person to take 4 breaths of each puff through the spacer. Remember: shake, 1 puff, 4 breaths.
If you don’t have a spacer, simply give the person 4 puffs of their reliever directly into their mouth. Repeat this until the person has taken 4 puffs.
(3) Wait 4 minutes. If there is no improvement, give 4 more separate puffs as in Step (2).
(4) Keep giving reliever. Give 4 puffs every 4 minutes until the ambulance arrives.

1.4.4 Fire

Laser engraving and cutting can present a significant fire hazard due to the extremely high temperature caused by the laser beam. Should a fire occur, take the following steps as an emergency response:

(1) If the fire is small in size (no larger than a small trash can), you can use an extinguisher to put it out. Remember to cut electrical power before dousing the flame.
(2) If the fire is large, do not attempt to fight it yourself. Call for help immediately by pulling the nearest alarm.
(3) Move quickly to the nearest accessible exit. Notify, and assist others to evacuate along the way. Do not use the elevators.
(4) Contain the fire and the smoke by closing all doors leading into and surrounding the fire area. Do not lock them.
(5) After a total and immediate evacuation, call medical attention for the casualty.
