Notes

Links are to Mares service manuals or parts lists (2021 XR and 2022 PL) and are followed by the page number of the linked pdf.
The service manuals are issued every year or two. They were initially incremental, i.e. the information is only updated or replaced as new models become available and parts are updated. Later manuals appear to be comprehensive and include applicable technical bulletins. It is still a good idea to check all the applicable links for your regulator as individual pages may be updated or missing from later manuals and parts catalogs.
The 2016 manual is in German, it does include photos of fully disassembled regulators with English labels as well as color photos of the service process.
"Photo" indicates a photo of the disassembled stage. Parts are labeled and service kit parts are highlighted. These are very useful.
While not indexed here, the manuals also contain service information on other Mares products including Air Control, computers, BCDs, and spearguns.
We do not have every manual. The most recent manual we have is from 2022.
If you would like to help keep this page up to date by reporting errors or contributing additional information, please e-mail lowwall1 "at" gmail "dot" com or contact lowwall or Zef on Scubaboard.com or post on this Scubaboard thread.
