Whoo hoo! Just got my domino back!
I was worried that it wasn't covered under warranty (I purchased it used from a nice older hobbyist who hardly used it) and it was a pin-style so I figured I had to bite the bullet.
Turns out it was covered thankfully, since they replaced: the armature, the field assembly (field coil?), the switch linkage, bearings, and the fan air guide!
I'm glad I didn't have to find out how much that would have cost!
A big thank you to Festool service, you guys are awesome. Great, timely service. This is why we buy your tools.
