WILL crack from excess heat. Your engraver should arrive with about 2.1 quarts (2 L) of OMTech coolant already in place. Check the integrated gauge to confi rm the coolant level is normal. See §5.2.1 for instructions on draining and fi lling the reservoir tank if it requires any adjustment. -
Page 22: Security
Cover Shutoff (Interlock) Because of the risk of blindness, burns, and other injury from direct exposure to the invisible engraving beam, this device also shuts off the laser automatically when the protective cover is raised during operation. After ensuring that the emergency stop button works, you should also test that the cover shutoff works properly before conducting any other work on your machine. -
Page 23: Operation
4. Operation 4.1 Operation Overview Operate this laser marking machine only in accordance with all the instructions provided in this manual. Failure to follow the proper guidelines detailed here can result in property damage and personal injury. This section will address only some of the options and features provided by the operation software. Before beginning to use the machine, make sure that you have read this entire manual (particularly the Safety Information above), the separate software manual, and any and all warnings provided on the machine itself. -
Page 24: Instructions For Specifi C Materials
The threshold for the lowest setting is 10%. The laser will not fi re at any setting lower than this. It is NOT recommended to use the laser tube at full capacity, especially for extended periods. The recommended maximum power setting is 70%, as prolonged use above that amount will shorten your laser's service life. To increase engraving depth, increase the amount of energy per unit area by increasing the laser's power or the number of loops or by slowing down the speed parameter. - Page 25 Ceramics When engraving on ceramics, generally use moderate to high power. Using more loops rather than higher power and lower speed can help avoid cracking the material during work. Be mindful of the health risk posed by dust generated from ceramic engraving, especially for repetitive industrial applications. Depending on the material and the amount of work, a fan or even full ventilation system may be required to address the problem.

Page 36: Maintenance
5. Maintenance 5.1 Maintenance Overview The use of procedures other than those specifi ed herein may result in hazardous laser radiation exposure. Before any cleaning or maintenance work, always switch off the device and disconnect it from power. Always keep the system clean, as fl ammable debris in the working and exhaust areas constitutes a fi re hazard. -
Page 37: Cleaning The Focus Lens
Clean the viewing window with mild cleansers and a lens or cotton cloth. DO NOT use paper towels as they can scratch the window and reduce the cover's ability to protect you from laser radiation. Clean the interior of the main bay thoroughly, removing any debris particles or deposits. -
Page 38: Cleaning The Mirrors
11. Repeat the same cleaning process on the other side of the lens. NEVER use a cleaning tissue twice. Dust accumulated in the cleaning tissue could scratch the lens surface. 12. Examine the lens. If it is still dirty, repeat the cleaning process above until the lens is clean. Do not touch the surface of the lens after cleaning. -
Page 39: Cooling System Maintenance
5.3 Cooling System Maintenance NEVER touch or adjust your engraver’s water supply while your engraver is still connected to power. In addition to the regular cleaning above, check that the coolant level remains in the green (NORMAL) zone of its gauge before and after each use. -
