Interlock; Cover Shutoff - Omtech POLAR+ User Manual

5.1 Interlock

Because of the risk of blindness, burns, and other injury from direct exposure to the invisible
engraving beam, this device shuts off the laser automatically when parts of its protective housing
are opened.
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.
