Water Shutoff
Because of the danger posed by an uncooled laser tube, this engraver also shuts off the laser automatically when the
water cooling system malfunctions.
After ensuring that the emergency stop button and cover protection both work, you should also test that the water
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. Cut off the fl ow of water by crimping or tying the two hoses. (Take care not to damage the hoses themselves
in this procedure.) 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. If the laser does
not fi re, the automatic shutoff is working fi ne; simply release the two hoses to begin circulating water again and
continue setting up your engraver.
Laser Path Calibration
Although our factory calibrates your entire system during assembly, it is possible for the laser tube, the focus lens,
and/or one or more of the mirrors to be jostled out of alignment during shipment. As such, it is recommended that
you perform an optical alignment test as part of setting up your machine. See the Maintenance section below for
step-by-step guidance. If the red dot locator does not turn on with the machine, check its power connections or
contact customer service.
Air Assist
Your air assist should arrive preinstalled and correctly wired. Simply check that it is correctly configured and
connected as shown. If any tubing or wiring needs to be reconnected, shut off all power to the machine (including
by pressing the emergency stop) before adjusting anything. Check that its air intake fi lter is in place, clean, and not
obstructed by any nearby objects.
3.10 Security
For your own safety and that of passersby, this engraver can be locked shut using the provided key. It is
recommended that you use it to lock the machine between sessions, preventing any unauthorized operation of the
machine.
