3.9 Initial Testing
Emergency Shutoff
Because of the risk of fi re and other hazards during engraving, this engraver includes a large and easy-to-reach
emergency stop button near the control panel. Press it down to stop the laser tube instantly.
When your engraver arrives, its e-stop is already pressed and must be pulled up to allow the laser to function. You
should test that it works properly before conducting ANY other work with your machine. Start the water cooling
system, place a piece of laserable scrap material on the workbed, close the cover, and press PULSE to fire the
laser. Hit the emergency stop button and observe whether the laser stops instantly. If the laser continues to fi re, the
emergency stop is not working and must be replaced before the engraver can be used. Turn off the machine and
contact customer service.
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. Start the water cooling system, place a piece of laserable scrap
material on the workbed, close the cover, and press PULSE to fi re the laser. Release the button. Taking care not to
expose yourself to seeing or being hit by any possible refl ected laser light, open the cover as little as possible and
attempt to fi re the laser again. If the laser fi res, the automatic shutoff is not working and must be repaired before the
engraver can be used. Turn off the machine and contact customer service. (Note that the visible red dot locator is
not the harmful active laser and may continue to work while the cover is open to help with positioning.)
