Water Shutoff - Omtech SH-G570 User Manual

7. Taking care not to expose yourself to seeing
or being hit by any possible reflected laser
light, open the cover as little as possible.
The laser should pause automatically and
an error will be displayed on the control
panel. If the laser continues to engrave
the design while the cover is raised, the
automatic shutoffs are not working and must
be repaired before the engraver can be
used. Turn off the machine and contact our
technical support team.
8. Turn off the engraver and press the Emergency Stop after the test is done.

3.7.3 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.
Always make sure the path is clear between the laser and its target.
Never allow foreign objects between the laser and the material being engraved.
Take care not to leave any part of your body in the laser path when it is in
operation.
1. Perform the same procedure as before but, crimp or tie the
water hoses, or unplug the water pump.
Be careful not to damage the hoses themselves and to only
briefly activate the laser.
The laser should stop completely and an error will be
displayed on the control panel.
• If the laser continues to 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 stops completely, 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.
2. Turn off the engraver after the test is done.
