Shutdown - Omtech POLAR+ User Manual

6.2.7 Shutdown

1. When you have finished your project, close
your engraving software.
2. Allow the cooling and ventilation systems to
continue to run until the air in the main bay is
clear and the tube has safely cooled.
3. Turn off the engraver using the laser key and
the main power switch and then turn off the
external fan.
For best results, fully unplug your engraver
or turn off its intermediary surge protector.
4. Open the cover and remove any dust or debris buildup from the workbed and the various
surfaces within the bay.
If the buildup is firm, use a partially damp cloth or similar tools that won't create scratches to
remove it. NEVER use abrasive papers or steel wools.
