Removal of plastic panel clear backing

Just got my Falcon 2 Pro 40W and have it up and running. I left the clear backing on the plastic panels while assembling and it seems very hard to remove. Is the backing needed to meet the laser light filtering spec or is it ok to remove? I am I better off to partly disassemble or has anyone had luck removing after the fact?


Like a clear protection foil? No it’s not needed. And yet it’s annoying to remove from acrylic sheets.
