3.8 Initial Testing
3.8.1 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.
3.8.2 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.
