Introduction

This guide will walk users through the proper cleaning and replacing, if needed, of the Epilog Laser Fusion M2 Lens. This should not be attempted unless you have received specialized training and permission from a LC.

Here is a in depth video to familiarize you with the cleaning process of the optics of the Epilog. Please follow the steps in the Dozuki as they differ from the video.

Sometimes the final focusing lens can get scratched or cracked. It will be necessary to replace the lens. Please inform a LC if the lens needs to be replaced.
