m2 AAD Optional Service Info
The m2 AAD has a 15.5-year lifetime, and does not require factory maintenance service during that time.
The unit can be inspected by your rigger annually. Info on that inspection is in the m2 manual at this link and in the photo below.

Still, there are scenarios where an m2 does need to go back to the manufacturer for inspection, repair or service due to an error message, damage to the unit or the like.
Some error codes can be resolved, so first read the manual from this link for more info. ChutingStar also carries common replacement parts for the m2 at this link, which can be installed by your rigger.
To send in an m2 AAD for service, first reach out to the manufacturer at this link to let them know of the issue or the service need.
If the issue does require sending your m2 to the manufacturer, it will be sent to this address:
MarS a.s.
Okruzni II 239
569 43 Jevicko
Czech Republic
Phone: +420 461 353 841
Include your return shipping address and a note on the issue.
There is no charge for the service. You do have to pay for shipping to MarS, but they will cover return shipping back to you. If a new cutter is needed, that will be replaced free of charge if you also include a completed Activation Report in your shipment, which can be downloaded at this link.
