During assembly of the helmet and welding filter, or during the replacement of
the protection screens, make sure that all parts are firmly in place thus prevent-
ing any light from entering the helmet. Should there still be any light entering,
repeat the procedure until the problem is eliminated, otherwise the helmet must
not be used for welding. Before placing the new protection screens, always re-
move the protection layers from both sides.
