Shane has closed the other thread for comments, but I think his last comment in it where he states that owners of the 55REQ should stop using it and get in touch with Festool should be posted at the top of the FOG. This problem seems to be quite important.

"Festool has notified the Consumer Product Safety Commission (CPSC) and Health Canada of a potential problem with the plunge mechanism on some TS 55 REQ Plunge-Cut Track Saws. While investigation is continuing, Festool, in cooperation with the Consumer Product Safety Commission (CPSC), intends to recall affected units. If you have a TS 55 REQ Plunge Cut Track Saw, please discontinue use immediately and call Festool directly at 1-855-784-9727.
