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. Release the e-stop and press the reset button 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.
Automatic Shutoff (Interlocks)
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 either the protective cover or the front access door is opened.
After ensuring that the emergency stop button works, you should also test that these shutoffs work 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. Repeat this process with the other interlocks, using the reset button to
restore power after each has been activated.
