5 Initial Testing
5.3 Water Shutoff
Because of the danger posed by an uncooled laser tube, this engraver also shuts off the laser
automatically when its sensors do not detect the correct water flow.
You should test that the water shutoff functions correctly:
1. Perform the same procedure as before but, crimp or tie the water hoses instead, and attempt to
fire the laser.
Be careful not to damage the hoses themselves and to only briefly activate the laser.
2. Choose one of the following options based on your situation:
•
If the laser does fire, the automatic shutoff is not working and must be repaired before the
engraver can be used. Turn off the machine and contact our technical support team.
•
If the laser does not fire, the automatic shutoff is working correctly. Release the two hoses
and run the water system for a minute or two, checking that no damage or leaks have
occurred.
Always make sure the path is clear between the laser and its target.
Never allow foreign objects between the laser and its target. Take care not to
leave any part of your body in the laser path when it is in operation.
