    The aim of all edgers is to obtain a final shape on a lens, by removal of material. This process generates dust whose type depends on the lens and the materials used. The materials used for coating the Essilor wheel and consumed during its use are not toxic or allergenic. Nevertheless, users must check that the ground materials are not toxic.

    It is an electrical appliance compliant with the applicable safety standards. In the event of malfunction, repairs must be carried out by qualified personnel approved by Essilor. Otherwise, user safety is likely to be compromised. In the event of a long period of non-use and before maintenance and/or replacement of certain accessories, you must unplug your edger from the mains.
