Emergency Shutoff

In case of the risk of fire and other hazards during engraving, this engraver includes an easy-to-reach
Emergency Stop button. Pressing it down stops the laser tube instantly; turning it clockwise unlocks
it. When your engraver arrives, its Emergency Stop button is initially pressed. It must be unlocked
before use.
You should test that it works properly before conducting ANY other work with your machine.
1. Turn on the water cooling system.
Confirm that the cooling system has been activated.
2. Turn the Emergency Stop button clockwise
to unlock it.
3. Press the control system power button to
turn on the engraver.
Confirm that the air assist and exhaust fan
have been activated.
4. Hit the Emergency Stop button and observe whether the engraver powers down.
If the Emergency Stop is not working and must be replaced before the engraver can be used,
turn off the machine and contact customer service.
5. Turn off the engraver after the test is done.
