TwoTrees Team SAFETY GUIDELINES Warning: Laser engraving machine cannot directly carve or cut material that reflects the light,may cause injury. The product has a high engraving speed and is not recommended for indus- trial cutting. And the laser head is consumable. Do not operate the laser head directly with your hands . Please wear goggles. The laser diode is a sensitive component,please prevent static damage. (This product has an electrostatic protection design.but there is still a possi- bility of damage). We do not assume any responsibility for any improper use of this equipment or any damage or damage caused by improper use. The operator is obligated to use this laser engraving machine only in accordance with its designated purpose, instructions in its manual, and relevant requirements and regula- tions. PRECAUTIONS Avoid looking steadily at the laser, which may damage your eyes. Avoid touching directly when the machine is working. You can place a metal plate under the engraved or cut object to prevent your table being burned through. Avoid combustible object or gas. Keep it away from children or pregnant women. Do Not take apart the laser without instructions. Do Not use it on material that reflects the light. Protective eyewear should be worn by anyone nearby during use. Turn off the power when not use. Nearby objects present a risk of pinching or crushing injury. Please follow the instruction,due to misuse will be at your own risk.
