3.9 Initial Testing

Emergency Shutoff
Because of the risk of fire 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 fire, 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 fire the laser. Release the button. Taking care not to expose yourself
to seeing or being hit by any possible reflected laser light, open the cover as little as possible and attempt to fire the laser
again. If the laser fires, the automatic shutoff is not working and must be repaired before the engraver can be used. Turn
off the machine and contact customer service.
